This is an OpenGL based, real-time ray tracer for visualizing 3D polygon meshes loaded from OBJ files.
- C++
- OpenGL and GLSL shading language
- GLEW, GLFW libraries
- Assimp library for loading OBJ files
- Shader storage buffers
The performance was optimized with bounding volume hierachies (BVH-tree), meaning that the bounding boxes are divided along the longest axis. The longest axis is always placed on the average centroid of the polygons. The whole tree is stored in a plain array and sent to a shader storage buffer in the fragment shader. The traversal is taken place in the fragment shader and the contstruction of BVH-tree is on the CPU side.
