Imperfect Ray-Bundle Tracing for Interactive Multi-Bounce Global Illumination
نویسندگان
چکیده
Introduction A bidirectional sampling method with raybundles [TO12] enables high-quality global illumination, but computation time of ray-bundles depends on the number of sample directions and the number of primitives. This poster proposes an approximate ray-bundle tracing based on imperfect shadow maps (ISMs) [RGK∗08]. ISMs accelerate light path visibility tests using a point-based rendering. In this poster, we accelerate ray-bundle based eye path generation using this point-based technique. Our technique computes multi-bounce global illumination at interactive frame rates.

Cached Multi-bounce Solution and Reconstruction for Voxel-based Global Illumination
We address the main shortcomings of the voxel-based multi-bounce global illumination method of Chatelier and Malgouyres (2006), by introducing an iterated cached method which allows increasing sampling coarseness at each bounce for improved efficiency, and by introducing a ray-tracing based reconstruction process for a better final image quality. The result is a competitive accurate multi-bounc...
متن کاملInstant Global Illumination on the GPU using OptiX
OptiX, a programmable ray tracing engine, has been recently made available by NVidia, relieving rendering researchers from the idiosyncrasies of efficient ray tracing programming and allowing them to concentrate on higher level algorithms, such as interactive global illumination. This paper evaluates the performance of the Instant Global Illumination algorithm on OptiX as well as the impact of ...
متن کاملInteractive Global Illumination using Fast Ray Tracing
Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield high quality renderings but are far too slow for interactive use. We present a new parallel global illumination algorithm that perfectly scales, has minimal preprocessing and com...
متن کاملDIRmaps : Discretized Incident Radiance Maps for High-Quality Global Illumination Walkthroughs in Complex Environments
Realtime ray tracing and interactive global illumination have recently made significant progress, allowing for ray traced rendering quality even in highly complex scenes. Nevertheless, high-quality global illumination is currently still limited to offline computations, as existing interactive techniques are applicable only to simple scenes, BRDFs, and/or lighting conditions. For realistically c...
متن کاملInteractive Global Illumination in Complex and Highly Occluded Environments
Global illumination algorithms have traditionally been very time consuming and were only suitable for off-line computations. Recent research in realtime ray tracing has improved global illumination performance to allow for illumination updates at interactive rates. However, both the traditional off-line and the new interactive systems show significant limitations when dealing with realistically...
