Automatic Handling of Materials in Nested Volumes

We present a novel and simple algorithm to automatically handle nested volumes and transitions between volumes, enabling push-button rendering functionality. The only requirements are the use of closed, watertight volumes (along with a ray tracing implementation such as NVIDIA RTX that guarantees watertight traversal and intersection) and that neighboring volumes are not intended to intersect each other, except for a small overlap that actually will model the boundary between the volumes.
