Abstract

Mirroring the development of rendering algorithms for polygonal models, z-buffer style rendering for point-based models has given way recently to more advanced methods. A fast raycasting based approach [Wald and Seidel 2005] shows shadows, but does not demonstrate reflective effects. The more general raytracing approach [Linsen et al. 2007] is substantially slower.

We advance the state of the art by ray tracing point models in real time. Our system relies on an efficient way of storing and accessing point data structures on the GPU. We hope that this leads the way for future work towards more realistic global illumination effects including soft shadows, simultaneous reflection & refraction, and caustics.

Ray tracing-based interactive diffuse indirect illumination

Despite great efforts in recent years to accelerate global illumination computation, the real-time ray tracing of fully dynamic scenes to support photorealistic indirect illumination effects has yet to be achieved in computer graphics. In this paper, we ...
Real-Time Volume Caustics with Image-Based Photon Tracing
CADGRAPHICS '11: Proceedings of the 2011 12th International Conference on Computer-Aided Design and Computer Graphics

Rendering of volume caustics in participating media is often expensive, even with different acceleration approaches. Basic volume photon tracing is used to render such effects, but rather slow due to its massive quantity of photons to be traced. In this ...
Real-time volume caustics with adaptive beam tracing
I3D '11: Symposium on Interactive 3D Graphics and Games

Caustics are detailed patterns of light reflected or refracted on specular surfaces into participating media or onto surfaces. In this paper we present a novel adaptive and scalable algorithm for rendering surface and volume caustics in single-...
