In Autodesk Softimage, you can precisely control every part of the 2D texturing pipeline using texture projections and texture supports. Each time you apply a 2D texture to an object, you must define a texture projection.
Once you define the projection, its texture support appears around the object. You can also create projections and supports before you apply any textures.
• The texture support is a graphic representation of how the texture is projected on the object. It defines the type of projection and applies textures to your 3D objects using that definition. By default, an object’s texture support is constrained to the object; otherwise, animated objects would move through space without their projection.
• Texture projections exist on the support and record the correspondence between pixels in the texture and points on the object’s surface—in other words they define where the texture is projected on the object.
You can transform a texture projection to define the part of the object to which the texture is applied. You can then add any number of projections, adjacent or overlapping, to the support.
The important thing to note is that the texture support actually applies textures to the object based on coordinates defined by the projection.
The texturing process works similarly to a slide projector. In this analogy:
• The texture image is the slide.
• The texture support is the slide projector.
• The texture projection is the area where the slide actually appears on the screen.
• The object, or its material node, is the screen itself.
Now imagine a slide projector that can project multiple slides simultaneously and precisely control where each one appears on the screen. That’s how texturing works in Softimage.
