- tinyobjloader for OBJ loading
Text References, listed in order or relevancy. Much of the code can be found in [1], while the theory is can be found largely covered in [2]. Implementation details are assisted by volppm (above), and [3]4 and [4] are used as reference for Photon Mapping. [5] Contains the approach taken, where a global radius is set across all pixel points similar to the approach taken by volppm. [6], [7], and [8] provide more reference on photon mapping and volumetric rendering theory.
