Reorder Buffer: An Energy-Efficient Multithreading Architecture for Hardware MIMD Ray Traversal
(ACM Siggraph, 2015)
In this paper, we present an energy- and area-efficient multithreading architecture for Multiple Instruction, Multiple Data (MIMD) ray tracing hardware targeted at low-power devices. Recent ray tracing hardware has ...
Efficient Ray Tracing of Subdivision Surfaces using Tessellation Caching
(ACM Siggraph, 2015)
A common way to ray trace subdivision surfaces is by constructing and traversing spatial hierarchies on top of tessellated input primitives. Unfortunately, tessellating surfaces requires a substantial amount of memory ...
