COLLADA has been a
COLLAborative
Design
Activity for establishing an open standard Digital Asset schema for interactive 3D applications. COLLADA, since its 1.4.0 release, is a standard of
The Khronos Group where the consortium members continue to promote COLLADA to be the center piece of Digital Asset toolchains used by the 3D interactive industry.
COLLADA™ defines an XML-based schema to make it easy to transport 3D assets between applications - enabling diverse DCC and 3D processing tools be combined into a production pipeline. The interchange format provides comprehensive encoding of visual scenes Including shaders and physics, and even multiple versions of the same asset.
COLLADA FX enables shaders to be authored and packaged using OpenGL Shading Language so that leading 3D authoring tools can work effectively together to create OpenGL / OpenGL ES applications and assets.
