Contour plot for non-rectangular domain - General Usage - Julia

There was a previous thread on this, but the use case was too different from mine to be informative. I have a function defined over a triangle and would like to plot it as a contour plot but only in the triangular domain. Is there some way to do this? It’s not hard in mathematica (but seems not to translate to more “normal” plotting software). For a concrete example to aim at, consider f(x,y) = cos(2pi x)*sin(2pi y) over the triangle with vertices (0,0), (1,0), (0,1). I’d like the plot to be b
