Skin Animation with Vertex Shaders

Alex · 2003-07-09T12:13:42

Can someone explain to me how you would implement skin animation in a vertex shader? Most tutorials I have been reading on skin animation have suggested either transforming the vertices of the skin mesh manually, placing them in a dynamic buffer for rendering, or to use a vertex shader to perform the entire operation. However, they don''t give code examples or even algorithm layout, and since my vertex shader skills are still very limited, I don''t know where to begin. Thanks in advance for any response!

rather then storing a 4x3 matrix you can store a point and a quaterion that reduces it to only 2 constant registors, its a little more complex operation but theres an example in the nvidia sdk, only you can''t do any scaling in it, well you could put a single scale value in the .w part of the point''s registor
