We examine a rendering system that interactively ray traces n image on a conventional multiprocessor. The implementation i s “brute force” in that it explicitly traces rays through every scree n pixel, yet pays careful attention to system resources for acceleratio n. The design of the system is described, along with issues related to ma erial models, lighting and shadows, and frameless rendering. The syst m is demonstrated for several different types of input scenes . CR Categories: I.3.0… Expand

Interactive Raytraced Caustics

Ray Tracing Animated Scenes using Motion Decomposition

Ray tracing animated scenes using coherent grid traversal
TLDR
By incrementally computing the overlap of the frustum with a slice of grid cells, this work speeds up grid traversal, and achieves ray tracing performance competitive with the fastest known packet-based kd-tree ray tracers. Expand
Interactive Rendering with Coherent Ray Tracing
TLDR
For almost two decades researchers have argued that ray tracing will eventually become faster than the rasterization technique that completely dominates todays graphics hardware, but there is hardly any scientific analysis that supports this claim. Expand
The ray engine
TLDR
This GPU ray-intersection implementation reconfigures the geometry engine into a ray engine that efficiently intersects caches of rays for a wide variety of host-based rendering tasks, including ray tracing, path tracing, form factor computation, photon mapping, subsurface scattering and general visibility processing.
