By myself ive figured out a way to do dynamic animation of meshes without vertex weights.

But now I plan on animating a brute rendering 1 million vert mesh and itll be a humanoid, and I need to get it to walk and act.

With a low poly mesh, you dont need weights as much because the triangles themselves stretch between the limbs, but because this is a hipoly mesh theres no stretching area so I need to graduate the arm from the body and keep the shoulder there just bending a little when the arm moves.

This needs to be in a shader, and im not sure how to go about it, but I think it is possible because I saw a microsoft skinning demo and it had vertex weights.

Can anyone shed some light on the issue for me? - thanks.

No takers hey, well all I can think of is a keep 2 bone ids and 2 matrix weights per vert, because in most cases its 2 bones that merge together.
That could work, but is there another way??

I think most skinning systems go up to 4 bone influences per vert. 2 is probably enough for the limbs, but maybe not for the torso/hips, depending on how complicated your spine is.

Anyway, there should be plenty of google refs on skeletal animation and skinning out there, so do a bit of searching.

That's near the spot where I decided I'd drop Opengl and start using an engine.

Oh so, I was nearly on the mark anyway... ok thankyou.
