- Mapbox is an animated stand-in external process that generates a
- box and regularly tiles a planar projection of a single texture
- (and/or opacity) map on each of its six sides. It also has the
- ability to "slide" the texture map across the surface of the box
- during an animation.
-
- The common use of Mapbox would be to:
-
- 1. Make a cube in the 3D Editor (a non-cubic box can be used,
- but the texture will be stretched along the non-square sides if
- the box isn't a regular cube).
-
- 2. Apply any material with a texture map (and/or opacity map).
-
- 3. Assign any arbitrary mapping coordinates to the cube. It
- doesn't matter what kind of projection you use, since these
- mapping coordinates won't actually be used. (they're going to be
- replaced by parametric coordinates generated by mapbox.axp)
-
- 4. With the Modify/Attributes command, assign mapbox.axp to the
- cube. Set the tiling value for each of the sides with the
- slider, and then set the DeltaU (animated change in the texture's
- x-direction) and DeltaV (animated change in the texture's y-
- direction) to something other than zero if you want the texture
- to slide over the surface during an animation. The recommended
- values are in the 0-1 range, and values of 0.01-0.1 provide
- very smooth animation.
-
- Note: The aspect ratio of the texture map should optimally match
- the aspect ratio of the sides of the box. Therefore, if you're
- using a cube, a square texture is optimal.
