Does anyone know where I can find the most recent techniques and algorithms for vertex blending in skeletal animations? Derivations of blending matrices would also be a great help.
Have you looked at www.nvidia.com/developer ?
Also try www.darwin3d.com for Jeff Lander’s Game Developer article and source.
For a hardware based solution, try nvidia, for software try darwin3d.
The hardware versions have limits, like where do you get the shadow geometry from if the deformation is done in hardware? (although I’ve heard rumors that a pixel shader can figure it out via nvidia, but I’m not sure.)
Some nice extensions which could help here too…
