I was just wondering, how would you go converting a 3D function into a 2D function....

for example.....if I want to convert Perlin 3D to 2D....how would I do that??....
"His blood-terragen level is 99.99%...he is definitely drunk on Terragen!"


Do you mean that instead of having 3D perlin blobs you have 2D ones that then extend forever up and down when put in the 3D context?  If that's the case, using a Transform shader with y-scale set to a billion trillion would be close enough to what you're looking for.

Depends on what you're trying to achieve. You could take a slice of a perlin by feeding it into a flat terain and then extracting the colours.
