What Format for 3d Models for Stage 3d

In an As3 project is there yet a ‘standard’ or ‘recognised’, format for storing of 3d models within worlds.

Orininally I was parsing obj,3ds,dxf and fbx files within my projects including associated bitmaps and other info to recreate the models in my world. But this seemed incredibly messy, slow and with near unlimited steps to go wrong.

My solution has been to turn individual models into Flash Swfs, that contain a variety of info, such as xyz,uv, normals, textures. However all this data is what I call “Compressed Buffer Ready”

This means I can use the models in my projects like a library and switch them from one app
to another with ease.

Next question, how are other kirupa users handling this ?
