Here’s a Fenisoft 3D raytracer, a sister product with the Fenisoft 3D scanline renderer. The difference here being, of course, that instead of using a scanline approach with a zbuffer, I “project” rays out to determine intersections.

My teacher made the comment that most people show off their raytracers by showing some spheres hovering over a checkerboard. Of course, I have seen this in my days with POV, so I couldn’t resist. Here it is, in all its glory: balls over a checkerboard (with a nice polygon – no meaning implied by using a triangle)
