- Texture Mapping
-
- To Apply a Texture Map to an object:
- Access the Attributes window (Ô£ø-2); select Textures from the pull-down menu;
- choose the PICT image you want to apply as a texture, then drag its icon to the
- Attributes bin in the object’s Cell Info dialog. The icon expands to an
- Attributes Icon.
-
- Double-click an icon in the Attributes-Textures window (Ô£ø-2) to display the
- PICT full-size.
-
- About PICTs --
- To use a PICT as a Texture it must be 72 dpi resolution.
-
- If the PICT will show in the rendering close to the camera, then it should be
- large in dimension (640 x 480 pixels or higher) in order to avoid pixelization of
- the PICT image.
-
- For the PICT icon to show in the Attributes window (Ô£ø-2), it must be in the
- Presenter Plug-ins folder before you launch Presenter. To avoid having an
- excessive number of PICTs in the Plug-ins folder, store the PICTs in a separate
- folder, then put an alias of that folder into the Plug-ins folder. This is a handy
- way to keep PICTs for different projects organized as well.
-
-
-
- All settings for PICTs may be used in the same way for QuickTime movies.
-
-
-
- Expanded Attributes Icon (six buttons; Velocity/Time curve button)
- Double-click on the icon to access the Mapping Method dialog box.
- Click on a button to toggle it on/off.
-
- Apply To (far-left three buttons)
- Top button (check box icon) to apply the Attribute to the item whose Cell Info
- Attributes bin the icon is residing.
- Middle button (folder icon) to apply the Attribute to the folder (and its children
- (folders and objects)) whose Cell Info Attributes bin the icon is residing.
- Lower button (pencil icon) to apply the Attribute to the individual objects in the
- folder (does not include folders) whose Cell Info Attributes bin the icon
- is residing.
-
- Apply to ND Cells (left three buttons)
- Applies the Attribute to any ND Cells in the Script window that are colored the
- same as the button.
-
- The Collision Detection Animator - Attributes Icon has one extra button at the
- top-right. This button determines the color of ND Cell that will be generated by
- the Animator.
-
- Mapping Method dialog box
- Note there are four display-only windows (Top, Front,Ride side views)
- showing a wireframe preview of the object being mapped and the PICT
- image (distorted to fit the display).
-
- Except for polygonal meshes, and 3D Primitives, a red positioning mesh will
- show in the display-only windows. The red positioning mesh corresponds to
- the size/position of the PICT in relation to the object.
-
- For all but Projection, the large Grid window displays a solid-line box
- corresponding to the PICT image on the grid corresponding to the entire
- surface of the object. Drag the solid-line box around to position the PICT
- image on the object surface, while observing the red positioning mesh.
-
- When Projection is selected the Grid window displays a wireframe preview of
- the object, and the solid-line box corresponding to the PICT image. Drag in
- the Grid window to position the projection of the PICT image on the object
- (the object appears to rotate about its center point -- however, the object in
- the scene is unaffected by this rotation.)
-
- Mapping Method (pull-down menu)
- Choose the manner in which you wish to map the PICT to the object:
- Wrap -- red positioning mesh adheres to the surface of the object.
- Projection -- red positioning mesh shows as flat 2D.
- Cylindrical/Spherical/Cubical
- These three methods can be used for mapping onto objects that
- are similar in shape to a Cylinder (or Sphere or Cube). These mapping
- methods employ a combination of Wrap and Projection. The image is
- projected from its position on the Cylinder (or Sphere or Cube) onto
- the object.
- Cylindrical -- red positioning mesh adheres to a “cylinder” closely
- surrounding the object.
- Spherical -- red positioning mesh adheres to a “sphere” closely
- surrounding the object.
- Cubical -- red positioning mesh adheres to a “cube” closely
- surrounding the object.
-
- Apply Texture To (pull-down menu)
- Choose to apply the map in a particular manner.
-
- Color -- applies the PICT image so that the color of the map replaces the
- color of the object where it is applied.
-
- Stenciled Color -- applies the PICT image so that the color of the map
- replaces the color of the object where it is applied; BUT uses the 4th
- Channel (Alpha Channel) on the PICT image file to knock-out parts of the
- image, showing the object color. The Alpha Channel parts to be knocked-
- out must be black.
- The PICT image must have the 4th Channel and be saved as 32-bit PICT
- to use this setting.
-
- Bump -- applies a gray-scale (internally computed for color PICT) image of
- the PICT to emboss the object (no actual change to the geometry or object
- color). Make an entry in the z-scale data field to determine the depth/height
- of the emboss (use a negative number to reverse the direction of the bump.
-
- Custom... -- access expert texture mapping functions. See Texture Mapping
- folder for detailed explanation of use of the expert texture mapping functions.
-
- Center x, y, z (three data fields)
- Make entries (number) to precisely position the center of the solid-line box
- (PICT image) in the Grid window. Use for minor adjustments to the position
- of the image not possible by the intuitive dragging of the solid-line box.
-
- Scale x, y, z (three data fields)
- Make entries (number > 0) to precisely enlarge reduce the solid-line box
- (PICT image). The solid-line box is pre-scaled so that one of the dimensions
- has a scale value of 1 (wrap method); corresponding to the entire length of
- the surface in that dimension. So, changing the Mapping Method will
- require you to re-scale the solid-line box to get the proper sizing of the
- image on the object.
-
- Use only the x-scale and y-scale for scaling the solid-line box; the z-scale is
- reserved for Bump mapping. If the image maps as a mirror image, use a
- negative number for the appropriate dimension (x or y) to flip it back.
-
- Orientation x, y, z (three data fields)
- Used only when employing Projection Mapping Method. Make entries to
- precisely set the rotation of the wireframe preview in the Grid window. Use
- for minor adjustments to the position of the image not possible by the
- intuitive dragging of the solid-line box.
-
- Movie Parms... (button)
- Only available when mapping a QuickTime movie as a texture. Click to
- access the Movie Parameters dialog box. See the Tmap doc.pdf file for
- more detailed information about this dialog box.
