This is a hlsl based node system for creating real-time effects. It very fast; runs at around 200 fps with a few typical filters (edge detect, blur, colorgradients, perlin noise) and I have never seen it go below 60 fps. It does this at HD resolutions. It has a few very nice filters like "time to geometry" : It does a treshold on video and builds geometry around the edges with marching cubes, connecting each frame with the previous one. Build with xna.
