The screenshots below are from a debugging session on a shadow ray-tracing program.
The program uses a
BSP tree data structure1.
Geometry representing the BSP tree was written out by debugging code and then viewed interactively in maya.
Each box represents a terminal node of the tree.
The colors of the boxes indicate the number of primitives contained in each one, with green having the most
and white the fewest.
1More precisely a kd-trie.
