# Module rs_pbrt::accelerators

source · [−]## Expand description

Acceleration structures are one of the components at the heart of any ray tracer. Without algorithms to reduce the number of unnecessary ray intersection tests, tracing a single ray through a scene would take time linear in the number of primitives in the scene, since the ray would need to be tested against each primitive in turn to find the closest intersection.
