SPINNER Beta 1

Hello!  Thank you for purchasing SPINNER, a scene layout tool for assembling VRML worlds in a realtime
rendered environment.  Using SPINNER, you will be able to import 3D objects in several formats and assemble
them into a VRML world. Along the way, youÆll be able to manipulate these models in many ways: scale, move,
rotate, color, duplicate, modify textures, etc.  .  There are thousands of 3d files on the Internet.  Download free
object from our website:  http://www.3dweb.com


No Uninstaller

1. Assuming you installed into: ôc:\SPINNERö, and your windows directory is : ôc:\windowsö, hereÆs how to
uninstall
2. At a DOS prompt enter the following command: deltree c:\SPINNER
3. Answer æyÆ at the prompt
4. At a DOS prompt enter the following command: ôdel c:\windows\igl*.*ö
5. At a DOS prompt enter the following command: ôdel SPINNER.iniö

Conventions

Single menu items and multiple menu selections are represented with brackets as follows, respectively:  [Key1]  or
[Key2] [Key3].  For example, [Object] [New Sphere] means click on the æObjectÆ menu option in the 3D View,
drag the left mouse button to the submenu option æNew SphereÆ then select that option.   Keystrokes that should be
pressed simultaneousely are represented by brackets.  For example, the bracketed items <Control> or  <Select>
indicate that you should hold down the Control key while selecting an object with your left mouse button.  Also if
we say <Control> click, this means hold the Control key while simultaneously clicking on an object with the left
mouse button.

The term æsceneÆ refers to a SPINNER file containing objects.  When you save a scene it is saved as my_scene.3dw.
You can export a scene to a VRML format which becomes my_scene.wrl.  Keep in mind that you must æExportÆ to
VRML format not just save a file as a my_scene.wrl under the [File] [Save] menu.

Whenever we say æclick on an object,Æ we mean, press the left mouse button then let go.  So unless we specify a
particular mouse button, we always mean the left mouse button. Right Mouse Click means to press the right mouse
button.

When we say æDragÆ an object, we represent this action as clicking and holding the left mouse button while moving
the cursor  or an object around.

When we say æRight and Left Mouse ClickÆ we represent this action as simultaneously clicking on the left and right
mous buttons.  Usually we use this action to climb and dive (pitch, roll, yaw for all you 3D buffs).

Words in quotations usually mean to enter them with the keyboard (such as enter, ôLight1ö as the new light
object).  Words in quotations could also imply an action to be performed at dialog boxes.  For example, click on the
ôYö radio button or Click ôApply.ö   All other uses will use the æsingle quotation marks.Æ


Overview Of Windows

The first two windows appear at the top of your monitor.

3D View    From this window, you can view the current scene in a real time 3D solid-filled rendered
window.    modifying the viewpoint (see æFly ModeÆ under Options menu). The user may
also pick objects in the world (see æPick ModeÆ under Options menu) and move objects
around inside the universe (see æObject FlyÆ under options menu). This is also the windows
where you pick individual polygons for editing.

Object Master    This window displays a tree of objects currently in the scene. The user may select different
objects by clicking on the object name. If control is held down and you click on another
object, multiple objects may be selected and modified. This is useful for using the alignment
or moving multiple objects.

The next three windows appear on the bottom of  your monitor.

Ortho Windows:     The bottom set of windows are called Orthogonal or Ortho Views.  These windows are
useful for visualizing your objects in one plane at a time.  You can not pick (select) objects
from these windows (in Beta I) but you can move and rotate preselected objects (objects
highlighted in blue) in any of these windows.  You can only move objects which are
selected.    If you selected multiple objects from the Object Master, you can move them
simultaneously in any of the Ortho Views.

  Top View    A viewpoint looking down the scene (along the Y axis).  This is also called the X-Z plane.

  Front View    A viewpoint looking at the face of the scene in line (along the Z axis).  This is also called
the X-Y plane

  Side View    A viewpoint looking at the side of the scene (along the X axis). This is also called the Y-Z
plane.


Icon Bar

The icon bar at the bottom of the 3D View contains some of the more frequently used options in the File Menu bar.
They are as follows:



Icon    Alternate Key Stroke(s)    Description

New Document    [File][New]     This icon creates a new scene;  you will be asked to
save     your current one.  You can not have more than
one scene loaded in SPINNER.

Open Folder    [File][Open]     Opens a folder.

Disk     [File][Save As]      Saves your current scene as my_scene.3dw

Airplane    [Options][Fly Mode] or <F2>    When this icon is depressed, you are in Fly mode
which means you (the camera) are flying through the
scene.

Pick    [Options][Pick Mode] or <F3>    When this icon is depressed, you are in pick mode
which means you can ôpickö or select objects from
the View window.  When objects are picked, a blue
box (called a bounding box) encompasses the object.
In addition, the objectÆs name in the Object Master
window will be highlighted in red.

Four-way Arrow    [Options][Object Fly] or <F4>        When this icon is depressed, you are in object fly
mode.  This mode allows you to move the object in
space while your viewpoint is stationary.

Magnifying Glass    [Options][Fly Mode] or <F5>        When this icon is depressed, you can zoom in (left
mouse button) and zoom out (right mouse button)
from within the 2D Ortho Views.

Block    [Object][New Block]    Launches a dialog box to create a block in your
scene.  The default is a 2X2X2 cube centered at the
origin (x=0, y-0, z-0) with a default color of gray.

Cylinder    [Object][New Cylinder]    Launches a dialog box for creating a cylinder in your
scene.  The default is a cylinder 2 units high with 8
sides and a radius of 1 unit.  This default cylinder
object is really an octagon which is 2 units high.

Sphere    [Object][New Sphere]    Launches a dialog box for creating a sphere.  The
default is a sphere with five faces in the latitudinal
direction, five faces in the longitudinal direction and
a radius of one unit.

Cone    [Object][New Cone]    Launches a dialog box for creating a cone.  The
default cone is one with a radius of 1 unit, a height
of 2 units and a tessellation (number of sides) of 8
units.

Light Bulb    [Object][New Light]    Launches a dialog box for creating a new light.  The
default light is a white directional light located at the
origin and pointing in the x=0.5, y=0.2,z=1
direction. This default light source is an infinitely
distanced light whose rays are parallel (i.e., the sun).
This light points toward xyz=(0.5, 0.2, 1).  SO, in
effect this light shines over your left shoulder.
Currently once you create a light, you can not edit it.

Letter ôAö    [Object][New Text]    Launches a dialog box for creating 3D text.  The
default text is white lettering centered at the origin.
You must enter text in the white area at the bottom
of the dialog box.

3 Rectangles    [Object][Import]    Imports a 3D model (NFF, 3DS, DXF, etc.)

Open Blue Box    [Object][New Group]    Adds a group node. This is also the node you use for
embedding WWWAnchors links in objects.

Airplane with + sign    [View][New Camera]    Adds a new perspective camera node.

    Backface:     Checking this box makes the terrain visible on both sides. This decreases
framerate in the view window as twice as many faces are calculated
    Visible:     Checking this box makes the terrain immediately visible in the view window

[New Light]    Launches a window with several options used to define the characteristics of a new light.
Right now there only directional lights are viewable in SPINNER.  However,
you can export all three:  directional, point and spot.  In SPINNER, lights
must appear before the objects they intend to illuminate.  For example, you
must have light source at a higher point into he Object Master tree. the
examples below, we will use a house to illustrate the differences between a
point, directional and spot light.

    Name:     Defines the name of the new light in the universe
    Location:     Defines the XYZ location of the new light in the universe
    Direction:     Defines the XYZ tilt, roll and facing of the new light in the universe
    Visible:     Checking this box makes the light immediately visible in the universe
    Intensity:     This slide bar defines the overall brightness of the light- sliding it to left
creates a dimmer light, to the right is brighter.

    Directional:     Checking this circle defines the light as illuminating outward in the direction
set under the æDirectionÆ option.  The default for a  directional light
illuminates from the origin and points toward x,y,z = (0.5,0.2,1).  This is
analogous to a sun hovering over your left shoulder.   The location of the
directional light (the origin) is irrelevant; only the direction matters.  We
include the location coordinates so that you can locate or place it in a
convenient spot.  A direction light straight downward (normal to the roof)
illuminates both the top of the roof (assuming the roof is flat) and the top of
the floor.  This really does not make sense in our world (i.e., a roof on earth
will shade the floor).  To ôcorrectö this behavior

    Point:     Checking this circle defines the light as illuminating outward from all
directions similar to a light bulb.  So if you have a point light in a house, the
floor and ceiling will be illuminated.   The closer objects are to the light
source, the brighter they will appear; but the relationship between brightness
of light and distance from objects depends on the VRML viewer you are using.
The direction of a point light is irrelevant; the location is relevant.

    Spot:     Checking this circle defines the light as shooting a beam outward from the
direction set under the æDirectionÆ option.   Right now, according to the
VRML spec, the cutoff angle in a spot light is 141 degrees.    You will be able
to control the ôconeö of the light source in Beta 2.  The direction and location
of a spot light is relevant.

    Color:     Launches a box allowing the user to set the color of the light; default is
white


The chart below may be helpful in understanding the differences between a point, spot and directional light:


                Location Matter?            Direction Matter?

Point                yes                no

Direction            no                yes

Spot                yes                yes




[New Text]    Launches a window with several options used to define new text in the universe

    Name:     Defines the name of the text in the universe
    Location:     Defines the XYZ location of the text in the universe
    Save as Polygons:
    Visible:     Checking this box makes the text immediately visible in the universe
    Color:     Launches a window allowing the user to define the color of the text in the
universe
    White Box:     Allows the user to input text that will be converted into a 3D object in the
universe


[Deselect All]    Deselects all selected objects in the universe

[Duplicate Selected]     Makes a new exact duplicate of the object(s) selected

[Modify Selected]    Launches a sub menu of several options:

    Color:     Launches a window that allows the user to modify the selected object(s)
color
    Scale:     Launches a window that allows the user to modify the selected object(s)
XYZ scale in the universe
    Name:     Launches a window that allows the user to modify the selected object(s)
name
    Texture:     Launches a window that allows the user to change the selected object(s)
texture
    Location:     Launches a window that allows the user to change the selected object(s)
XYZ location in the universe

[Delete Selected]    Deletes the selected object(s) from the universe

Tools Menu


[Path]    This feature allows you to create a path for a camera or an object for adding animations and motion
to you 3D Scene.  The VRML spec does not currently support this tool, but once it does you will be
able to quickly add object motions (an actual solar system) or animations based on triggers.

    Name:            Name of the path

    Number of Tweens:    Determines how smooth you want the path.  The more tweens, the
smoother the path.

    Type of Interpolation:    Determines the shape of the pat.

    # of Nodes:

    Current Node:

    Reverse

    Oscillate
    Repeat:
    Visible:


[Align]    This feature is useful for aligning objects with each other.  For example, you may want to ôdropö a
lamp EXACTLY on top of a table.  With this tool you can align multiple objects along any axis.
You can also control where the objects are aligned with respect to one another.  For example you can
align two object so that their center points share the same X value or you can align two objects so
that their sides share the same X value.  In the first case one object is inside the other; in the second
case the two objects are side-by-side. Launches a window that of several options used to define the
type of object alignment.  An explanation of each.

    Axis:    Defines which axis the user wants to align the selected objects along
    Center:     Checking this circle makes selected objects align along the center of
the anchor object
    Touch:     Checking this circle makes selected objects touch each other along
the selected axis of the anchor object
    Top:     Checking this circle makes selected objects align along the top of the
selected axis of the anchor object
    Bottom:     Checking this circle makes selected objects align along the bottom of
the selected axis of the anchor object
    Anchor:    Allows the user to define the anchor object from the currently
selected objects
    Apply:    Applies the align routine to the selected objects
    Spacing:    xxx


Speed Menu


[Textures-]    Selecting this item toggles whether or not textures are visible and rendered in the
universe. If off, frame rate increases
[Smooth Shaded]     Selecting this item toggles whether or not smooth shading is applied to all objects in
the universe. If off, frame rate increases
[Wire Frame]     Selecting this item makes all items in the universe defined as wireframe. If on, frame
rate increases
[Wire Fly]    Selecting this item makes all objects in the universe rendered as wireframe only while
the user is flying. As soon as flying stops, the objects are rendered as
solid fill. If this option is on, frame rate increases
[Constraints / Sensitivity]    Launches a window with several options in it:
[Rotational Constraints]    These three boxes may be checked to stop any rotation attempted along
    the X Y or Z axis.
[Linear Constraints]    These three boxes may be checked to stop any æmovementÆ or æflyingÆ     attempted
along the X Y or Z axis.
[Linear Sensitivity]    This bar may be moved to adjust the æstep sizeÆ and æspeedÆ of any movement
    made in the View window.

Options Menu

[Auto Sensitivity]    Selecting this item makes the step size of the viewpoint correspond with any object that
is created or imported

[Auto See All]    Selecting this item relocates the viewpoint everytime a new object is created or
imported, placing the viewpoint in a position where all objects are in view. This option
is useful when importing objects that may ôswallowö your camera (viewpoint).  For
example, if you import an object that is very large, then the new object will surround
your camera.  If this option is enabled (checked), then your active camera will ôback
upö enabling you to automatically  ôsee allö of your scene.  Or if you import an object
which is behind you, your active camera will position itself so that all objects are in
view.

[Fly Mode]    Places the 3D View into fly mode.  When you are in object fly mode, your cursor
appears as an airplane.  There are six degrees-of-freedom when flying  your viewpoint
(modifying the active camera) in SPINNER.  These six degrees-of-freedom are
controlled by positioning and holding down either the left mouse button, the right
mouse button or a combination of both the left and right mouse simultaneously.  The
further away from the crosshairs you place the airplane icon, the faster your viewpoint
changes.

    Forward and Backward     Position the airplane above the crosshairs and hold the
left mouse button to move forward; below the crosshairs
to move backward.

    Rotate Right and Left    Position the airplane to the right of the crosshairs and
hold the left mouse button to rotate right; left of the
crosshairs to rotate left.  This is analogous to a
helicopter rotating about its local axis.

    Up and down    Position the airplane above the crosshairs and hold the
right mouse button to fly up (to raise your viewpoint up
-y units); below the crosshairs to fly down.


    Move right and  left    Position the airplane to the right of the crosshairs and
hold the right mouse button to move (pan); left of the
crosshairs to fly left.

    Rotate clockwise
    and counter clockwise:    Position the airplane to the right of the crosshairs and
simultaneously hold both the right and left mouse
buttons to rotate the viewpoint clockwise (the scene will
appear to rotate counterclockwise); left of the crosshairs
to rotate the viewpoint counterclockwise.

    Climb and Dive    Position the airplane above the crosshairs TO CLIMB,
BELOW

[Pick Mode]     When this is selected, the user may left click on any object in the view window and it
will be selected. Left clicking again will bring up an options box with several options:

    Stretch X    Checking this circle locks the stretching onto the X plane
    Stretch Y    Checking this circle locks the stretching onto the Y plane
    Stretch Z    Checking this circle locks the stretching onto the Z plane
    Scale    Checking this circle locks the stretching onto all planes, allowing the
object to be scaled
    Axis    World-Checking this circle scales and stretches the object around the
center of the universe
    Local     Checking this circle scales and stretches the object around the center
of the selected object(s)
    Slide Bar    Sliding left or clicking the left arrow scales or stretches smaller,
sliding right or clicking the right arrow scales or stretches larger
    Textures    Shaded- checking this box makes the texture darkened or lightened
depending the amount of light hitting it

[Object Fly]    Puts the view window into object fly mode. When the left mouse button is pressed in
the view window the selected object will move along the Z axis and rotate around the Y
axis. When the right button is pressed in the view window the object will fly along the
X and Y axis. If both buttons are pressed in the view window and the mouse is moved,
the object will rotate around the X and Z axis

[Strict VRML]    When this option is selected, the document, when saved to .WRL format, will comply
rigidly to VRML spec 1.0

[Show Statistics]    When this option is selected the framerate and polygon count of the current scene will
be displayed in the status bar of the view window

[Render Always]    When this option is selected the scene will constantly redraw itself even when no object
manipulation or viewpoint movement is occurring. This allows for a constant framerate
to be calculated, but slows down the system considerably.
