I'm interested in a way of plotting a solid defined by
0 <= z <= f[x,y], g[x,y] <= 0,
that's better than what I've been doing, which is to fake it using
ClipFill and PlotRange something like this:
f[x_, y_] := (-x + 1)*(y^2 + 1)
Plot3D[ If[x^2 + y^2 <= 1, f[x, y], -1],
{x, -1.1, 1.1}, {y, -1.1, 1.1}, PlotRange -> {0, 3},
ClipFill -> None, PlotPoints -> 100, Mesh -> False,
BoxRatios -> {1, 1, 1}]
Any ideas?
