Initializing Tree Graphics

To load the textures and initialize the vertex and index buffers of a CTree object, call CTreeRI::InitGfx(). Note the hierarchy of the tree classes:

“CCore” is defined in the Core library.

“CTree” is used as an alias for CCore in Forest.h.

“CTreeRI” is a templated class in need of platform-specific rendering policies.

“Render Policies” represents the render policies (textures, shaders, vertex buffers, etc) for any of the supported SpeedTree platforms.

“CTreeRender” is defined in each of the platform's renderer header files (e.g. OpenGLRenderer.h, 360Renderer.h) and is a CTreeRI object with the appropriate render policies passed in as template parameters.

The typical order for initializing a tree object is:

Load an SRT file or memory block into a CTreeRI object using CTreeRI ::LoadTree() (CTreeRI is derived from CCore).
Call CTreeRI::InitGfx() with that tree object so that it will be ready to render using the Render Interface library.

Note: The source files MyPopulate.cpp/h give an example of how to load trees and initialize their graphics. Specifically, see CMyPopulate::LoadBaseTree() and CMyPopulate::InitBaseTreeGraphics().
