The COLLADA DOM patch 3, COLLADA RT, and COLLADA FX Loader have all been made available at the COLLADA DOM sourceforge site.
The COLLADA RT is sample code that reads in a COLLADA document via the DOM and converts the structures into renderable data. It has two flavors, 1. A viewer application so you can quickly view your data, and 2. static libraries so you can use the COLLADA RT as an import API.
The COLLADA FX Loader is a library that reads COLLADA documents via the DOM and creates the effects in the CG 1.5 runtime. These effects can then be applied to geometry in your scene via the cg runtime.
