I'm struggling with something simple I think (didn't check "advanced" for this thread at all!)

displacement maps are very easy with jit.gen

but I'd like to figure out how to use them in polar coordinates "without so much cpu stuff"

basically, even if my case is a bit more complex, imagine a sphere.

And here I'd like to use a very basic one (one plane) to alter altitude of points on my sphere (only normals alteration)

hi there,

I love to generate texture with jit.bfg.

Not sure if i understand correctly, see patch to see if i did and i definitely love to know how to do this in a shader too...
