Shader Output

Please help me.
how can i create an output in shader containing a float4X4

mm…shaders cannot have output pins. they operate on the GPU. the only way of getting information back out of the shader is rendering something and using Pipet (EX9.Texture) to retreive individual pixels color values.

Is that a definitive answer? Otherwise is there any other way to “program” at the pixel level without using shaders (e.g. like the draw function in processing)? Pixel per pixel functions make things like shape recognition for example difficult

yep. shaders still can’t have outputs. for now the only other way to work at pixel-level is using FreeFrame.

also it would be interesting if someone could have a look into writing a processing wrapper as a vvvv plugin
