Whitted ray-tracing for dynamic scenes using a ray-space hierarchy on the GPU
EGSR'07: Proceedings of the 18th Eurographics conference on Rendering TechniquesIn this paper, we present a new algorithm for interactive rendering of animated scenes with Whitted Ray-Tracing, running on the GPU. We focus our attention on the secondary rays (the rays generated by one or more bounces on specular objects), and use ...
Distributed ray tracing
Ray tracing is one of the most elegant techniques in computer graphics. Many phenomena that are difficult or impossible with other techniques are simple with ray tracing, including shadows, reflections, and refracted light. Ray directions, however, ...
An adaptive acceleration structure for screen-space ray tracing
HPG '15: Proceedings of the 7th Conference on High-Performance GraphicsWe propose an efficient acceleration structure for real-time screen-space ray tracing. The hybrid data structure represents the scene geometry by combining a bounding volume hierarchy with local planar approximations. This enables fast empty space ...
