In parallel implementations the technique can be used to create coherent intersection tasks, allowing demand-driven scheduling with low communication overheads.

Basically, it works as follows: for each point in an screen (a pixel), it constructs a ray starting from the eye and passing through that point. This ray, ...

Spatial subdivision techniques have greatly improved the efficiency of ray tracing but further optimizations in that direction will be difficult to achieve.
