0ctobyte/raytracer

A ray tracer implemented in C++ capable of rendering scenes described by a Lua based DSL. Developed as a project for the CS488 course.

Ray Tracer

A ray tracer implemented in C++. It traverses a scene file described by a Lua based DSL. This was written for a project for the CS 488 course at the University of Waterloo.

Check out the site to see some of the images rendered with the ray tracer!

Build & Usage

Run make in the src directory to compile the program.

To run the program (<scene> is the lua scene file):

./rt <scene>.lua

raytracer's Issues

Bump mapping primitives

Bump mapping has not been implemented for all primitives.

Test refraction on all primitives

Need material parameter to enable/disable glossy reflection

Also, use the cosine weighted distribution algorithm to generate perturbed reflection rays rather than the algorithm I am using now

Difference CSG doesn't always work

Doesn't always work see csg2.lua

Implement adaptive anti-aliasing
