RaylibRaytracer

a weekend raytracing project written using the raylib library and glsl

Details

• Utilizes SSBO to store mesh data on the GPU
• Performs all raytracing calculations within a fullscreen-quad fragment shader
• Utilizes a BVH acceleration structure for fast ray-scene traversal
• Utilizes cosin weighted hemisphere sampling for roughness scattering

Lessons Learned

• Future raytracing implementations need a more efficient way to store data in GPU memory
• Use compute shaders for future implementations
• Vulkan is far more optimal for raytracing, but OpenGL can get the job done for smaller-scale projects

Tip

After creating this project, I was requested to write about it in the ForAll Math magazine associated with Saint Louis University. If you are interested, you can read my article here
