The Viewport
*cMThe Project Designer viewport is the main viewport for the display of project
*2Presources in a view.  It is scalable in size from a maximum of 640x480 pixels to
*2Ga minimum of 256x192 pixels.  As you  resize the viewport the resources
*20displayed in the viewport are resized as well.
*AJThe viewport display can be toggled from the camera view (the view that is
*2Frendered) and 3 orthographic views which show not only the location of
*2Lobjects, but also that of lights and the camera.  In addition, when the Move
*2QToolbox is displayed, the viewport can be divided into quadrants so that all four
*2#views are displayed simultaneously.
*APThe view that is displayed in the viewport is referred to as the "current" view,
*2Obecause it is the view that will be rendered.  To make a view current, drag the
*2Idesired view resource icon and drop it into the View Well on the Resource
*2PManager, or drop it directly over the viewport itself.  All the object and light
*2Jresources that are in the current view now have their names highlighted in
yellow.
*AKThe viewport has two display modes: wireframe and rendered.  You can toggle
*=$among these display modes using the
 button on the Command Bar.
tHHowever, Renderize Live EZ changes display modes automatically depending
*2Lon what you are doing, so you usually shouldn't need to change display modes
*2Gmanually.  For example, when you drop a resource into the Move Well (to
*2Mactivate that resource for spatial manipulation in the viewport), the display
*2,mode will automatically change to wireframe.
The Resource Manager
*cKLocated to the left of the viewport, the Resource Manager displays lists of
*2Bproject resources, as well as two Command Wells that determine the
*2 manipulation of those resources.
The View Well
*PJThe View Well is the "doorway" to the Project Designer viewport.  Use this
*2MWell to combine resources into a view, and display that view in the viewport.
*2NWhen a view resource is dropped into this Well, it becomes the current project
*2Jview: any objects and lights in this view are displayed in the viewport as
*2Nwireframe models.  The way the view appears in the viewport is a factor of the
*2-camera focal length that is set for the view.
*AOIn addition to view resources, object, light and image resources can be dropped
*2Linto the View Well, but only if a view already exists in the Well.  When you
*2Idrop an object or light resource into the View Well after a view has been
The Project Designer
Times New Roman
Gdropped in, that resource is added to the view.  When you drop an image
*2>resource into the View Well, it becomes the view background.
The Move Well
*PMThe Move Well is used to reposition resources in 3D space.  The resource that
*2Ois dropped into this Well can be re-oriented independently in the current view,
*2'assuming that it exists in that view.
*ANLight, object and view resources can be repositioned in 3D space.  When one of
*2Nthese resources is dropped into the Move Well, the viewport display changes to
*2Mwireframe mode and the Move Toolbox is displayed so that the current resource
*2Pcan be manipulated in 3D space.  In addition, the wireframe of the resource that
*2Iis being repositioned is displayed in yellow.  Objects and cameras can be
*2Omanipulated in any of the viewport displays, but lights can only be manipulated
*2;in one of the orthographic displays (Side, Front or Top).
*AIIn addition, when an object is displayed in the Move Well, you can drop a
*2Mmaterial resource over the object in that Well to assign that material to the
object.
The Edit Well
*PKThe Edit Well is the "doorway" to the Resource Designer Windows.  There are
*2Kdifferent Resource Designer windows for each of the five project resources:
*2Iviews, objects, lights, materials and images.  There is also an Animation
*2HDesigner window used to define animations; however, this designer Window
*2Gcan only be accessed by selection from the Edit pop-down command on the
*2    Menu Bar.
*AKWhen you drop a resource into the Edit Well, the Resource Designer for that
*2Iresource type is opened, and that resource is dropped into the window for
*2Pmanipulation.  For example, if you drop an object resource in the Edit Well, the
*2OObject Designer appears, loaded with the object that you dropped into the Well.
*AKIn addition to opening Resource Designer windows by dropping the icons into
*2Othe Edit Well, you can also select on the desired resource with the right mouse
*2Bbutton and choose the Edit option from the icon menu that appears.
The Resource Palettes
*PKThe Resource Palettes list the resources that are available for the current
*2Kproject. A separate Resource Palette exists for each resource type, and the
*2QResource Palette that is currently displayed is determined by the resource button
*2(that is pressed on the Resource Manager:
+BS0 This button displays the View Resource Palette;
*S2 This button displays the Object Resource Palette;
The Project Designer
Times New Roman
1 This button displays the Light Resource Palette;
*N4 This button displays the Material Resource Palette;
*X1 This button displays the Image Resource Palette.
tOEach resource is displayed as a "postage stamp" icon in its respective Resource
*2PPalette.  Each resource icon visually displays the attributes of the resource it
*2Lrepresents.  If there are more resources than can be displayed in one of the
*2NResource Palettes, the slider bars on the left of each Resource Palette may be
*2Bmoved to scroll the icons and show a different set of resources.
*AMA button above each Resource Palette is marked with the name of that resource
*2Ctype.  This button is used to enable or disable resources globally.
*AETo employ or process a resource, the resource icon may be dragged and
*2Ldropped into one of the Command Wells (described above), or you can point to
*2Othe desired resource icon and press the right mouse button to display a menu of
*2Ooptions.  The use of resource icons is described in the Introduction to Project
*2*Resources section earlier in this chapter.
#Rendering Views: The Render Toolbox
*cJThe Render Toolbox controls the functions necessary to perform renderings,
*2Oboth into the Project Designer viewport and directly to high resolution file on
*2Ldisk.  The Toolbox contains three distinct areas: Render to Screen, Options,
and Render to File.
*S0The Render Toolbox is displayed by pressing the
 button on the Command
tKBar, or by selection from the Toolbox pop-down on the Menu Bar.  The Render
*2KToolbox also appears automatically as soon as you load a view into the View
Well.
The Render to Screen Buttons
*PNNormally, views are rendered in the viewport until they appear as desired, and
*2Konly then are they rendered to disk file.  This is because rendering to the
*2Oviewport is faster and more conducive to iterative work than rendering to disk.
*ALRemember that the viewport display may only be 8 bits (256 colors), but that
*2Pthe image is output to 24 bits (16.7 million colors) when it is rendered to disk
*2Mfile.  In addition, the maximum viewport size is only 640x480 pixels, but the
*2.rendered file can be output to any resolution.
+Br2 High Quality Renderings: The Render Image Button
tKThis button renders the current view into the viewport, using the same high
*2Nquality rendering method that will be used when the final image is rendered to
The Project Designer
Times New Roman
Hdisk.  The resolution quality of the rendered view is determined by the
Npop-down menu, described below.  In addition to resolution quality, the way in
*2Hwhich a rendering appears depends on the Options that are enabled on the
*27Render Toolbox; these options are also discussed below.
*AGThe resolution at which the view is rendered depends on the size of the
*2Iviewport.  The default viewport size is its maximum size, 640x480 pixels.
*2OReducing the size of the viewport will speed rendering time, but at the expense
of quality.
*P2After an image is rendered into the viewport, the
 button can be used to
K"quick-save" the rendering as an image resource.  This command is described
in full below.
*d>Setting the Viewport Render Resolution: The Test Pop-Down Menu
)MC pop-down determines the resolution quality of the rendering, where
R"1" is full quality.  The higher the value set here, the clearer the rendered view
*2=will appear, but the longer it will take to render that view.
*AISelect on this pop-down, and a list of rendering quality choices appears.
*2NHighlight the desired value on the list and release the mouse button to select
this value.
+Bk5 Rendering a Part of the View: The Render Area Button
IThe Render Area button performs a high quality rendering at "Test:1" in a
*2Nspecified area in the viewport.  Use this command to "spot-render" those areas
*2Rof the view that have been changed; it is faster than rerendering the entire view.
*2JIf no area has been defined in the viewport, this command will not work.
*AGTo define an area to render, first make sure that the Render Toolbox is
*2Ldisplayed.  Move the pointer into the viewport, then click and hold down the
*2Rleft mouse button at a point that represents a corner of the area that you wish to
*2Jrender.  Now as you drag the pointer, a rectangle expands with your cursor
*2Pmovements.  When the desired area is enclosed by the rectangle, release the left
*2Nmouse button to complete the area definition and select this command to render
the defined area.
*AJThe area you define is remembered and used each time you select the Render
*2*Area command, until you define a new area.
+Bq- Iterative Rendering: The Render Quick Button
IThis button performs a "quick-render" for the current view.  The rendered
*2Mimage is of lower quality, but the rendering speed is a bit faster.  Use this
*2Hcommand to perform "quick and dirty" renderings when you are involved in
*2Giterative processes such as color studies.  When a quick-rendered image
approaches your goal, use the
, button to perform a viewport rendering that
The Project Designer
Times New Roman
tLmore accurately approximates the quality you can expect of the image when it
is rendered to disk.
*AOThe speed that this option offers comes at a price: a quick-rendered image does
*2Nnot display shadows or reflection maps.  Spot lights and attenuated lights are
*2Ktreated as normal point lights.  Anti-aliasing, texture mipping and texture
*2Msampling are disabled.  In addition, texture maps may not appear as expected,
*2@depending on the position of objects in relation to the camera.
+Bj, Saving Viewport Renderings: The Save Button
tPPress this button to save the rendering that appears in the viewport as an image
*2Oresource.  This provides a convenient method for saving iterative renderings of
*2Fa view for comparison purposes, such as during light or color studies.
*AKWhen you press this button, an image resource is created out of the current
*2Mcontents of the viewport, and given the name "Test1".  This image now appears
*2Eas a postage stamp icon in the Image Resource Palette on the Resource
*2IManager.  If an image resource named "Test1" already exists, this command
*20will automatically name the new image "Test2".
*APNote that these images are not automatically saved to disk.  If you wish to save
*2Qa test image to disk file, drop that image into the Image Designer and select the
*2DSave Image command from the File pop-down menu.  In any case, if you
*2Hattempt to exit Renderize Live EZ without saving these images to disk, a
warning message will appear.
The Options Buttons
*PNThe rendering options affect the quality of the rendered view in different and
*2Nsignificant ways.  The position of these buttons are taken into account during
renderings generated with the
  and
 commands.
tKEach of these buttons affects rendering speed, and therefore should be used
*2Iselectively.  For example, if you are rendering to review texture mapping
*2Ichanges, you may not need to cast shadows.  If you don't need to see your
*2Ntexture maps at their highest quality, you may not need to Mip and Sample your
*2    textures.
 The Compute Shadows Button
tNGlobally toggles shadows off and on.  When this button is disabled, no shadows
*2Nwill appear when the model is rendered, even if shadows are enabled for lights
*2I(in the Light Designer) and objects (in the Object Designer).  To compute
*2<shadows into the rendered view, this button must be enabled.
The Project Designer
Times New Roman
 The Anti-Alias Button
KToggles anti-aliasing off and on.  Anti-aliasing is the graduation of color
*2Qbetween contrasting areas used to avoid the "stairstep" effect of angled lines in
*2Ka digital image.  This toggle allows test renderings to be made without the
*2+time-consuming computation of anti-aliases.
*O&When you select Anti-Alias, a related
 button appears.
 The Mip Textures Button
NThis button improves the texture quality of a rendered texture, but does so at
*2Ethe expense of rendering speed and memory usage.  When this button is
*2Kenabled, the system generates additional texture maps for each of the image
*2Otextures when the view is rendered.  These additional maps are used to create a
*2Kmore accurate representation of a texture as that texture is mapped onto an
*2Tobject.  Specifically, if the texture size is reduced, either through the scaling of
*2Mthe texture (in the Object Designer), or because the texture recedes from the
*2Kcamera in a rendered image, enabling this button may improve the appearance
of that texture.
*B)Note: Mip Textures must be enabled for a
 command (defined in the
*Object Designer window) to have an effect.
 The Sample Textures Button
QThis button improves the resolution quality of a rendered texture, but does so at
*2Othe expense of rendering speed.  When this button is enabled, texture maps will
*2/appear less pixelated as their scale increases.
 The Refine Textures Button
LSelect this button to enable anti-aliasing of the image textures as they are
*2Kmapped onto objects.  This option maximizes the quality of a texture during
*2Nvery high resolution renderings, but does so at the expense of system speed.
The Render To File Commands
*PQGenerally, a view is rendered to file only after that view appears correctly in a
*2Jviewport rendering.  This is because a view rendered to disk file is often
*2Arendered in high resolution, which is a time-consuming process.
*BFThe resolution at which the view is rendered to disk is set using the
X Res
Y Res
)kH type-ins located in the Render To File area of the Render Toolbox.  You
Kcan render to a maximum of 640x480 pixels. The aspect ratio of the rendered
view is determined using the
Aspect
)y& pop-down menu, located directly above
Dthe X Res and Y Res type-ins.  These commands are described below.
The Project Designer
Times New Roman
tOFinal renderings are generated in full color (24 bit); the color depth at which
*2Pthe image is saved depends on the file type and color depth selected in the File
*2MBrowser.  These file types are discussed in full in the Image Designer Window
chapter.
*APWhen a final render is executed, an image file is created and sent to disk.  The
*2Mway a view is rendered here (displaying shadows, anti-aliasing, etc), and the
*3<speed with which the view is rendered, is determined by the
p    Rendering
Options
 buttons.
 The Render Final Button
tOWhen you select  this button, a File Browser appears, and you can define a file
*2Otype, color depth, path and filename for the final rendering that you are about
*2Gto perform.  The view can be saved out to one of a number of image file
formats.
The Aspect Pop-Down Menu
Aspect
)yA pop-down menu is used to determine the aspect ratio of the image
tQthat is rendered out to disk file. The selection in this menu affects the numbers
that are entered into the
X Res
 and
Y Res
 type-ins.
tRThe default selection for aspect ratio is "4x3", which is the same aspect ratio as
*2Sthe viewport on the Project Designer.  If the aspect ratio is set to anything other
*2Mthan "4x3", the size of the viewport changes to represent the selected aspect
*2Sratio.  Using the slider bars located directly below or directly to the left of the
*2Gviewport (depending on the selected aspect ratio), you can position the
*2Nrectangle over the desired area of the view.  The area that is enclosed in the
*2Rrectangle is the area of the current view that will be rendered to file.  In other
*2Mwords, changing the aspect ratio may force you to "crop" your view to fit the
*2+desired aspect ratio in the rendered image.
The X Res and Y Res Type-ins
*PRThese type-ins allow you to select the output resolution of the file that contains
*2Hthe final-rendered view.  The values here determine the number of pixels
*2Ihorizontally (X Res) and vertically (Y Res).   Renderize Live EZ supports
*2Crendering output up to 640x480 pixels (320x240 pixels for animation
sequences).
*ANIf "Any" is the aspect ratio that was selected from the Final Aspect pop-down,
*2Pthen the X Res and  Y Res of the rendered image can be set to any value.  If one
*2Qof the other aspect ratios is chosen, then typing in the desired resolution for X
*2LRes will automatically set the correct Y Res value according to the selected
aspect ratio, and vice versa.
The Project Designer
Times New Roman
Rendering Multiple Views
*PIIf you have created several views in the current project, and you wish to
*2Qfinal-render all of these views to disk, it may be desirable to perform a "batch"
*2Krender so that you can define the rendering parameters for all of the views
*2Pindividually, then render them all as a group.  If your projects are complicated
*2Mor you are rendering to high resolution file, the final render process can be
*2Mquite time-consuming.  Batch rendering allows you to perform the final render
*2Gin an unattended mode so that it can be done at a more convenient time.
*B%Batch Rendering is selected from the
Options
 pop-down menu.
/Orienting Project Resources in a View: The Move
Toolbox
*cEThe Move Toolbox provides for orientation of camera, object and light
*=Jresources in the viewport.  The Move Toolbox is displayed by pressing the
wpwwpw
wwpww
wwpwwp
Kbutton on the Command Bar, or by selection from the Toolbox pop-down on the
*2JMenu Bar.  The Move Toolbox also appears automatically as soon as you drop
*24a view, object or light resource into the Move Well.
*AJThe specific movement and rotation buttons that appear on the Move Toolbox
*2Idepend on the resource that is currently loaded inthe Move Well.  Lights,
*2Mobjects, views and animations each have a unique set of movement and rotation
buttons.
 The Center Position Button
RPress this button to center resources in the camera view.  If the current resource
*2Qin the Move Well is an object, that object is repositioned so that it now appears
*2Hin the camera view.  If the current resource in the Move Well is a view,
*2Npressing this button repositions the camera so that all of the geometry in the
*2Oview appears within the camera's field of view.  If the current resource in the
*2RMove Well is a light, that light is repositioned at the camera.This button is very
*2:useful if you can't locate an object or light in 3D space.
 The Save Position Button
RPress this button to save the current position, rotation and scale information for
*2Othe resource that is currently displayed in the Move Well.  If after saving the
*2Lresource's position you re-orient that resource and wish to return it to its

t;Manipulating Resources in the Viewport: Mouse Functionality
*POTo manipulate a camera, object or light in the viewport, first load the desired
*2Kresource into the Move Well.  Then select a button on the Move Toolbox that
*2Pindicates the kind of action that you wish to perform.  Then move the pointer to
*2Othe viewport and drag the left mouse button to perform that action.  As soon as
*2Lyou position your pointer in the viewport, a message in the Title Bar of the
*29viewport indicates the action that is currently selected.
*AJThe Move Toolbox contains a different set of command selections, depending
*2Non whether a view, object or light is currently loaded into the viewport.  The
*2Hfollowing sections detail the commands available for each resource type.
*AINote that the Move Toolbox can be configured in the Preferences window so
*2Sthat instead of displaying a set of buttons that determine the functionality of the
*2Gleft mouse button, you can display a Mouse Command Bar, a pop-down menu

t.Defining Material-to-Object Relationships: The
Select Toolbox
*cNThe manner in which materials are assigned to an object when it is loaded into
*2LRenderize Live EZ depends on the kind of object that was loaded, and the way
*2Fthat object was loaded.  In some cases an object has only one material
*2Kassociated with it.  In other cases a single object can have many different
materials associated with it.
*AHThe Select Toolbox enables you to view and change the object-to-material
*2Hrelationships.  The commands in this Toolbox are used to see where on an
*2Kobject each material is assigned, and to change those definitions, break an
*2Qobject up into different material areas, or assign a single material to what used
*2#to be two separate material areas.
*AKNote that an object that has multiple material assignments can be broken up
*2Ointo multiple objects according to those material assignments.  This feature is
*2)discussed in the Object Designer Chapter.
Press the
; button on the Command Bar to open the Select Toolbox.  The
tFcommands in this Toolbox allow you to determine which material you are
*2Pworking with, then to define the objects or polygons that you wish to assign the
*2Ematerial to.  You can even move objects or the camera to get a better
*22perspective on the polygons that you wish to pick.
*AGWhen the Select Toolbox is displayed, the words TEMP MODE appear at the
*2Ibottom of the Project Designer viewport.  This means that any changes you
*2Rmake to the position of objects in the viewport will not affect their position for

*24necessary to view and edit the material assignments.
*d<Viewing Material-to-Object Relationships: The Materials Area
*PRUse the Materials area on the left side of the Toolbox to select the material that
*2Hyou wish to work with.  You can select a material by dropping a material
*2Nresource into the Current Resource Well on the Select Toolbox, or by selecting
*2?the material name from the pop-down list in the Materials area.
*AIWhen you select a material, all of the polygons to which that material is
*2Eassigned are highlighted with yellow polygons and green facets.  This
*2Mhighlighted area indicates the parts of the object that will take the current
*2&material definition during rendering.
*AOIf you wish to create a new material while in the Select Toolbox, you can do so
*@Gby typing in a new material name in the pop-down list and pressing the
tKbutton: a new material by that name is created, and loaded into the Current
Material Well.

;Picking Polygons to Add and Remove Polygons from a Material
Definition
*PNTo change a material area definition, first highlight the name of the material
*2Lyou want to change in the Materials area.  The polygons associated with that
*2Mmaterial are now highlighted in the viewport.  Now you can select polygons to
*2Obe added or subtracted from the current material definition.  To do so, use the
*2OPolygon Selection buttons on the right side of the Toolbox.  Select the desired
*2Hbuttons as described below, then draw a bounding box around the polygons
*2Iwhose material assignment you wish to alter.  After you have selected the
*@&desired polygons, you must select the
e"  button on the Change area of the
 Toolbox to effect those changes.
*S$Before picking polygons, select the
A# Mode button to display the Polygon
KSelection commands on the Toolbox.  Then, choose whether you wish to add or
*2,subtract polygons from the current material:
+BP: Clears all polygons from the current material definition.
*T& Add polygons to the current material.
*T+ Remove polygons from the current material.
@Then choose how polygons are to be selected in the bounding box:
+BOH Select all polygons that are surrounded or clipped by the bounding box.
*QJ Select only those polygons that are completely surrounded by the bounding

LOnce you have selected the desired buttons on the Polygons Selection area of
*2Jthe Toolbox, move the pointer into the viewport and depress the left mouse
*2Hbutton to drag a bounding box.  The polygons defined by the bounding box
*2I(either wholly contained in the area, or partially contained in the area,
depending on whether the
){' button is enabled) will be added to or
wwyww
wwyww
Dremoved from the current material definition, depending whether the
 button is enabled.

tOAnother way to add to or remove polygons from a material definition is to point
*2Kto the face that you wish to remove or include, then select and immediately
*2Orelease the left mouse button.  If the face that you selected on was previously
*2Rpart of the material, it is now removed; if it wasn't part of the material, now it
*L2After executing your changes, you must select the
 on the Change area of
t#the Toolbox, to execute the change.
*AOEach polygon and facet in an object can only belong to one material definition.
*2KTherefore, including a polygon in one material definition means removing it
*2<from the definition with which it was previously associated.
*d0Selecting Front-facing and Back-facing Polygons.
*f@What you see in the viewport is what you are selecting.  If the
tIbuttons are both enabled on the Command Bar, you are selecting backfacing
polygons and frontfacing ones.
*AMIf you remove polygons from a material definition and Apply the change, these
*2Nmaterials are assigned to the "default" material definition until such time as
*22they are added to a different material definition.
Applying Your Changes
*PMNone of your work assigning polygons to materials is recorded until you press
G button in the Change area of the Select Toolbox to apply your changes.
t7Changing the Viewport Display During the Select Process
*PMIf you are working on a large or sophisticated wireframe model, it may not be
*2Oeasy to isolate polygons for selection.  Therefore, Renderize Live EZ gives you
*2Qthe ability to move and rotate objects or the camera so that the desired polygons
*2(can be isolated in the viewport display.
*AJNote that the words TEMP MODE appear in the viewport at all times when the
*2LSelect Toolbox is enabled.  This means that any changes that are made to the
*2Oviewport display (moving, rotating or zooming in the viewport display) are only
*2Qtemporary.  As soon as you exit the Select Toolbox the display will return to the
*2&state it was in before you entered it.
*ALBefore you move an object or the camera, the desired resource must be loaded
*=Ginto the Move Well on the Resource Manager.  Next, you must select the
wpwwpw
wwpww
wwpwwp
tKMode button on the Select Toolbox to display the Viewport Control commands.
*AMTo move a resource in the viewport, first select the desired Viewport Control
*2Gcommand, the move the pointer into the viewport and drag the left mouse
*2Obutton to manipulate the resource.  The button definitions here are the same as
*2Kdescribed for object and camera movement in the Move Toolbox section above.

NIn addition to moving resources, it can be useful to zoom the viewport display
*2Kin order to more easily distinguish individual polygons for selection.  The
*28zooming buttons on the Command Bar can be used for this.
*AOFinally, note that the polygons selection process is greatly facilitated as the
*2Lnumber of objects in the viewport display is reduced.  Therefore, use of the
*2Rability to turn objects off  (this capability is described in the Resource Manager
*2Psection above) so that only those objects whose material definitions you wish to
*20edit are displayed during the selection process.
"Defining Colors: The Color Toolbox
*cMThere are many cases in which a color needs to be defined.  Renderize Live EZ
*2Rallows for the definition of a background color for the view, a fog color, a light
*2Tcolor, and colors for the matte, shiny and reflect properties of a material.  In all
*29cases, colors are defined using the same set of commands.
*T'To access the Color Toolbox select the
|  button on the Command Bar.  The
IColor Toolbox is also opened automatically whenever you select in a Color
*2EWell with the left mouse button.  When you do this, the Color Well is
*2Mdynamically linked to the Color Toolbox so that any changes made in the Color
*2FToolbox are immediately reflected in the Color Well that you selected.
*AKThe Color Toolbox can also be configured to appear as an independent window
*2Mthat "floats" above the Project Designer, thereby reducing the need to toggle
*2Abetween Toolboxes.  To make the Color Command Deck an independent
*2Fwindow, enable the Free Color Window button in the Preferences Window.
*AKThe Color Well on the left side of the Color Toolbox displays the "current"
*2Qcolor definition.  The central area of the Toolbox displays colors.  Selecting in
*2Nthis area changes the current color definition.  The way a color definition is
*3Gchanged depends on the selected color mode, and there are three modes:
 and
image
)k@.  Finally, there is a black color box and a white color box, so
.that these two colors can be selected quickly.
*APThe numeric values of the current color are displayed in both rgb and hsv at the
bottom of the Color Toolbox.
Defining a Color in RGB Mode
*PIRGB, which stands for Red-Green-Blue, is an additive color method.  Using
*2Dvarying amounts of red, green and blue, any color may be produced.
*AOThe central portion of the Toolbox displays three color bars, one each for red,
*2Pgreen and blue.  By selecting on the slider bar and moving it left or right, you
*2Pare subtracting or adding a color to the color definition.  The changes you make
*2Iare reflected dynamically in the sample color box on the left side of the
command area.
The Project Designer

Defining a Color in HSV Mode
*PHHSV, which stands for Hue-Saturation-Value, is an alternative method for
*2Ndefining a color.  Hue defines the shade or color of the equation.  Saturation
*2Qdefines the amount, or purity, of the color.  Value defines the brightness of the
*2=color from black, no brightness, to white, 100% brightness.
*AOThe central portion of the Toolbox displays three color bars, one each for hue,
*2Rsaturation and value.  By selecting on the slider bar and moving it left or right,
*2Nyou are decreasing or increasing the hue, saturation or value: the changes you
*2Nmake are reflected dynamically in the sample color box on the left side of the
command area.
Defining a Color in Image Mode
*POIn this mode, six scrollable images of the color space are available from which
*2Sto pick colors.  Scroll bars are available to look at additional areas of the color
maps.
