VXGI demo (WIP) | Voxel Cone Tracing Global Illumination | OpenGL

I recently implemented VXGI in my little rendering engine. The VXGI process is divided into 3 steps: First, the algorithm divides the whole scene into voxels (a concept similar to texel or pixel, but in 3d). Each voxel contains the average albedo and normal information of all inner fragments. Second, the algorithm injects diffuse lighting/radiance, containing shadow, into all the voxels. Besides, it also generates mipmaps for the radiance 3d texture. Last, VXGI computes one-bounce lighting results using voxel cone tracing. This tracing process is similar to ray tracing but saves computation resources because radiance voxel information is leveraged.
