Using QuickDraw 3D RAVE

This section illustrates how to use QuickDraw 3D RAVE. In particular, it provides source code examples that show how you can

• specify a virtual device
• determine which drawing engines are available and what features they have
• create and configure a draw context
• draw objects in a draw context
• use a draw context as an image cache
• use a texture map's alpha channel for transparency or as a blend matte
• render with antialiasing

These are examples of operations that an application might need to perform. To learn how to write and register a new drawing engine, see the section "Writing a Drawing Engine" .

The code examples shown in this section provide only very rudimentary error handling.
