Introduction to the Render Interface library

Directly dependent on the Forest library, the Render Interface library makes abstract graphics calls to efficiently render the forest, complete with shader loads, state changes, efficient vertex buffer rendering, shadows, lighting, and more. The Render Interface makes calls to empty graphics wrappers, making it a portable library.

The SpeedTree Runtime SDK offers several libraries that implement the rendering interface defined by this library. Each of these, save the OpenGL version, are platform specific.
