Abstract
According to one implementation, a system for rendering a volume includes a computing platform having a hardware processor, and a system memory storing a volume rendering software code. The hardware processor is configured to execute the volume rendering software code to receive data characterizing a volume to be rendered and to decompose the volume into a first volume portion and a second volume portion. The hardware processor is further configured to execute the volume rendering software code to perform a first tracking of a light ray in the first volume portion to determine a first interaction distance of the light ray in the first volume portion, perform a second tracking of the light ray in the second volume portion to determine a second interaction distance of the light ray in the second volume portion, and render the volume based on the shorter of the first and second interaction distances.
