WebFeb 17, 2024 · Play with the algebra and you'll see that the height of the polyhedron above the horizontal plane doesn't matter. The plane can be above the polyhedron, or pass through it, and the result will still be correct. So what we need is (1) a way to calculate the area of the base, and (2) a way to tell an "upper" face from a "lower" one. WebThe final generated polyhedra always has a maximum radius of 1 metre. This may mean that some extrusions cause the apparent base polyhedron to shrink in size relative to the external projections, but this is intended behaviour.
