If you''ve got access to vertex data and functions to load up a file then you could do it but scripting languages are designed for high level constructs not things like skeletal animation, it''d probably run rather slowly.

The fastest way would be to write your animation code in whatever your main language is rather than the scripting language. If you want animation object orientated then just have your animation functions operate on vertex streams with some sort of mechanism to pass vertex data from a mesh object to one of your animation functions before rendering it. If you still want to use a scripting language the fastest way to do it depends on what scripting language you are using.

It should be straightforward to implement animation from a scripting system as long as you leverage the actual playback code from within a compiled language. What kind of animation are you talking about? Vertex animation, skeletal animation or simply transform-based animation?

If you are doing vertex animation of a model, normally you have a collection of vertex data that represents multiple frames of animation. You could name these collections of frames something meaningful - "walk" or "run" or what have you. From your scripting language, call a function that plays the named animation on a mesh object.

Likewise, if you are implmenting transform or skeletal animation, you''ll want to do all of you animating in native code, but call the correct animation or the mesh from your script.

Starting out with an object oriented approach certainly can help with script interface design. What about having a "AnimationController" object that can be assigned an animation and pointed at a mesh object. In your code, you can do all the checks to make sure the vertex count matches, or the hierarchies are the same, and if so start playing the animation. The script can interface with the animation controller and perform whatever tasks it needs - IsAnimationFinished(), GetAnimationTime(), StopAnimation(), SetAnimationSpeed(), or what have you. If you use an AnimationController as a base class, and extend it to support vertex, transform and skeletal animation, then the script system can be made to look like all animation is handled the same, regardless of type.

Without further information I''m afraid I can''t really help more!
