3×3 Matrix filter for the GPU in Nuke! Yay!<\/p>\n


\nThere’s two hidden <\/span>nodes in Nuke, GpuOp and GpuFileShader, both are nodes that can run GLSL <\/span>shaders realtime in the Nuke viewers.<\/p>\n

I had a quick look at it eariler this year, one of the things that came out of it was a 3×3 matrix filter. Pretty much identical to the built in matrix in Nuke. But realtime on the gpu. While this nodes is pretty awesome for prototyping effects and creating interesting LUTs, it has all the limitations of any GPU shader. Some of them are :<\/p>\n
