Autodesk FBX SDK... Autodesk FBX technology provides a free platform-independent 3D authoring and interchange format that provides access to 3D content from most 3D vendors and platforms. The FBX file format supports all major 3D data elements, as well as 2D, audio and video media elements.
This C++ software development kit (SDK) that lets you import and export scenes in the .fbx file format. Using this SDK, you can create, access or modify various scene elements such as meshes, parametric surfaces, skeletons, lights, cameras and animation data.
Version 2009.3 technology now includes published source code for the FBX and COLLADA readers and writers, enabling developers to extend and adapt the code for use in custom pipelines.
PHOTEK Autodesk's commitment to the fbx format on Mac OSX is great news...
I only wish they could make AutoCad for Mac to help out all the Architects and Designers that are forced to use Windows... and whilst they are at it... it would be nice to have a 64bit version of Maya to match the Win and Linux versions... (Version 2009.1)
