creating a binary reflection tree consisting of transmission nodes and reflection nodes for determining whether a transmission is received or a reflection is received; and

pruning nodes in the binary reflection tree that do not contribute to the incidence, wherein the pruning eliminates rays that do not generate a transmission or a reflection on the observation region.

partitioning the source into distinct ray launching regions; and

assigning each section to a different processing engine for parallel processing.
