The COLLADA RT Loader is a sample that was developed to load COLLADA document scene files, and render them using CG 1.5. It provides scene heirarchy, cameras, animation, and skinning support as well as basic COLLADA_FX rendering with the assistance of the COLLADA_FX lib.
The COLLADA FX Loader project is a sample that was developed to load a basic COLLADA FX document, and to make all of the calls to the Cg / CgGL runtime to create and initialize the materials and effects defined in COLLADA. It also provides an API to apply those effects through calls to set and reset the pass state of an effect.
The sample projects complement the open source COLLADA DOM, an API that provides a C++ object representation of a COLLADA XML instance document.
