This paper presents a new method for representing Light Propagation Volumes using an octree data structure; and for allowing light from regular point light sources to be injected into them. The resulting technique uses full octrees with the help of a separate data structure for representing the octree structure. The octree structure enables light propagation to be performed at a lower resolution than the base resolution; resulting in fast propagation and overall faster rendering times. The implementation of the technique is capable of rendering the Sponza scene at 9 frames per second; which is 8% faster than the original LPV technique.
