Abstract

We present a method for integrating surface and volume caustics in a production path tracer. We combine progressive photon mapping with photon guiding in an on-demand framework that avoids the overhead of general purpose bidirectional algorithms. We turn bias into noise during rendering to improve adaptive image refinement and denoising.

Photon Differential Splatting for Rendering Caustics

We present a photon splatting technique which reduces noise and blur in the rendering of caustics. Blurring of illumination edges is an inherent problem in photon splatting, as each photon is unaware of its neighbours when being splatted. This means ...
Simplified photon mapping for real-time caustics rendering

The objective of this paper is to adapt photon mapping for real-time simulation of caustics. High-performance algorithm adapted for the GPU and implemented on the basis of cross-platform OpenGL and OpenCL APIs is proposed. For effective rendering of ...
Hardware-accelerated global illumination by image space photon mapping
HPG '09: Proceedings of the Conference on High Performance Graphics 2009

We describe an extension to photon mapping that recasts the most expensive steps of the algorithm -- the initial and final photon bounces -- as image-space operations amenable to GPU acceleration. This enables global illumination for real-time ...
