I need to make a 3D plot of a step function
For example, suppose that I want to plot the function f:[0,1]x[0,1]->[0,1] given by:
f(x,y) = 1 if x < y^2 and f(x,y) = 0 otherwise
I would like to use a LaTeX solution (preferably pstricks, but tikz is fine) instead of importing a figure from Asymptote
I couldn't find a solution using pst-3dplot, is there a package with a pre-build solution to plot his kind of functions?
