WebGL - TED DXML importer with armatures; animations needed

Yet another update. Now you can mess with the bones of whatever you imported, albeit unoptimized and rather slow, in comparison to the identical C++ program.

Next up is probably cleaning or testing animations. It is obvious that speed optimization is needed badly, but the math does not really change much; Javascript seems to be missing access to SSE type data. As well as mouse input not based on pixels, and joysticks, and a audio API, ect...

In a less complete sense, I modified the matrix conversion function to be smaller; though it's not computationally faster. The object with matrix animation/ armature animation is as follows:

Parent Armature Space Matrix * Default From Parent Matrix * Current Local Transform = Current Armature Space Matrix

Parent Armature Space Matrix => The transform of the parent, as calculated with current animation data.
Default From Parent Matrix => Upon loading an armature, calculate this by Parent^-1 * Current. This represents the initial rotational and positional offset from the initial bone positions to eachother, which allows your animation local data to be relative to that starting point.
Current Local Transform => The offsets, like position, rotation, scale. Depending on how you want to apply scale this can be tricky.
Current Armature Space Matrix => The final transformed position; send t his to the 'convertforshader' algorithm.

And, in effect, animating is only changing the set of local deformations over time, and possibly adjusting them with things like IK or mouselooks. And all that is best done with SSE operators.

I bent up this Chameleon Boss from Metroid: Other M.
