Based on https://github.com/NCCA/PBR and https://github.com/NCCA/QtNGL
This is an implementation of Interactive Indirect Illumination Using Voxel Cone Tracing [Crassin et al. 2011], created for my NCCA Masterclass assignment. Some aspects are heavily inspired by Cheng-Tso Lin's SparseVoxelOctree, and José Villegas' VCTRenderer.
