RayTracer

Summary

A Raytracer that receives a scene defined in lua, and produces an image output.

Getting Started

Compilation follows the standard process defined by the UWaterloo CS488 sample projects.

We use premake4 as our cross-platform build system. First you will need to build all the static libraries that the projects depend on. To build the libraries, open up a terminal, and cd to the top level of the CS488 project directory and then run the following:

premake4 gmake
make

This will build the following static libraries, and place them in the top level lib folder of your cs488 project directory.

• libcs488-framework.a
• libglfw3.a
• libimgui.a

NOTE: As the following is only the relevant Raytracer files, the build system/dependencies and premake4.lua definition files are all missing. The files in this project are provided as-is.

Dependencies

• OpenGL 3.2+
• GLFW

Notes

Objectives were completed as defined by the assignment.

The sample.lua scene that is defined is based on the simple.lua, and uses a compositions of items from the sample lua files.

Features:

• Uses a multi-threaded design to increase performance (number of threads can be specified at compile-time)
• Mirror reflections was the supported offical feature that was added to the project

Standing Issues:

• Currently there is an issue with the Mesh models. As it stands they only partially render (certain values do)
• This likely has to do with an issue with the algorithm that was being used
• Originally used an angle based algorithm (described here) but it did not render the objects
