Software Renderer

This is a small demo for learning GAMES101, GAMES202 and OpenGL. All rendering operations are completed on the CPU using C++, so it's cross-platform.

glm is used as the math library, and OpenGL is used to show rendered results.

I will improve it if I have spare time:)

Usage

git clone https://github.com/andrewg42/SoftRenderer
cd SoftRenderer
cmake -Bbuild
cmake --build build -j8
build/main
