Rendering 3 planes from jit.noise resluts in a geometry matrix that looks like a cube. What I want to do is change that cube into a cylinder. I am multiplying Z plane with oval (oval is white, surrounding is black) and it doesn't work. If I scale the Z plane with scalar, scaling works. If I scale Z plane with any matrix that has constant value in all the cells it works too.
In case you decide to check the patch, try different options from yellow umenu. You will see that "oval" option doesn't work.
