render

wherein I build 3D rendering tools in Carp, based on this book.

Raytracer

I built a simple software raytracer with

• ambient, point, and positional light,
• spheres as shapes (which is lame, I know),
• shadows,
• reflection, and
• varying opacity (without refraction for now).

It’s very simple and just about 150 lines of Carp, including the final dumping into a PPM file (I was using SDL at first, but rendering in SDL based on points is extremely slow).

Here’s an unexciting example picture:
