The C Real Time Raymarcher running on the GPU

Some nice new pictures of crtrm, the C Real-Time Ray Marcher, running on the GPU. This was something I have been putting off for a long time for various reasons, partially because I have a more limited toolkit in GLSL, and partially because I didn't want to complicate an already complicated render engine. In fact, I had to duplicate the render engine, and now I have to maintain parallel versions. But the pictures I am getting suggest it is worth the time and effort.

I really like this sketchy effect I'm getting due to Moire interference, so a future project will be emulating it in a shader.
