Another one with imaginary lights reflecting off an invisible surface.

Inspired by topographical maps.

While working on an algorithm to detect the intersection of two objects, some tests were needed. I put together test cases for various simple 2d and 3d objects such as lines, planes, spheres. For a more challenging test case, I created an bumpy terrain and tried to intersect it with a flat rectangle.

The test passed immediately, but I headed off on a tangent to create interesting, surreal landscapes. The results of that foray make up the next few posts.
