Detailed Description

The low level graphics interface to the engine.

In Torque the GFX layer provides access to abstracted low level graphics concepts. From script you have limited access to graphics rendering as it is usually too slow to do individual draw calls thru the scripting interface. For drawing its usually better to use the higher level gameplay objects.

Note:: Detailed technical descriptions of when to use specific GFXStateBlockData fields, how GFXBlendOp works, or other interfaces of that nature are outside the scope of this manual. Since Torque is based on DirectX and OpenGL any reference documents for those APIs will provide the background needed to learn about rendering.
