Retro Ray Tracer

I recently completed University of Waterloo’s Introduction to Computer Graphics Course. For the final project, I created a ray tracer that can approximate any scene with small cubes to create an old-school raster graphics video game aesthetic.

A detailed demonstration of the ray tracer is available on Medium.

Soft shadows via distribution ray tracing of shadow rays on area lights

Stencil mode. Edge-detection is used to draw outlines around 3D shapes.

Voxel mode. Here, geometric primitives are approximated with little cubes.

Stencil mode and depth of field
