Hardware-Accelerated Ray Tracing for Sci-Vis and Beyond     

Abstract: Using ray tracing for sci-vis is an obvious choice since GPU vendors integrate that technique as first-class citizen in their chip designs. Apart from the obvious approach to use ray tracing cores for first-hit computation, these hardware units are generally useful as they provide access to optimized tree traversal. If developers are able to map their algorithms to compatible problems implementable on that hardware they can exploit those properties and benefit from hardware acceleration. The talk will discuss applications and algorithms from sci-vis and beyond, which, by using hardware ray tracing, can be accelerated significantly. These algorithms include random access to spatial field structures or neighbor queries on scattered data or graphs. The talk will also discuss challenges when mapping such algorithms to the hardware, such as the need for clever combinations of hardware and software traversal in cases where multiple data structures are involved.
