various spline algorithms computed on the GPU HLSL shader which take parameters via texture maps and create spline meshes interpolating 3d positions with various algorithms. for usage with vvvv (vvvv.org) version 0.1: ribbon phong directional shading * linear interpolation * cosine interpolation * cubic interpolation * b-spline (third degree) * tcb-spline (hermite interpolation with tension continuity and bias control * bezier (cubic) * piecewise bezier (cubic)
