Managing Textures
QuickDraw 3D provides routines that you can use to get information about the characteristics of a texture. You can get the dimensions of a texture, as well as the number of channels and the number of bits per channel. You cannot, however, reset any of these texture characteristics (they are determined at the time you create a texture object). You can also get the current alpha and RGB channels of a texture. You can reset these characteristics to achieve special effects.
- Note
- To create a texture object, you need to create an instance of some subclass of the texture class. For example, you can create a pixmap texture object by calling
Q3PixmapTexture_New. See "Managing Pixmap Textures" on page 14-29 for information on creating and manipulating pixmap textures.
