Micropolygon Ray Tracing With Defocus and Motion Blur
A micropolygon ray tracing algorithm that is capable of efficiently rendering high-quality defocus and motion-blur effects.
Real-Time Lens Blur Effects and Focus Control
This novel rendering system for focus control and lens-blur effects supports physically based rendering and outperforms previous approaches by involving a novel GPU-based tracing method. The method is more general and can integrate advanced simulations, such as simple geometric lens models, lens aberrations, and various artistic effects.
OptiX: A General Purpose Ray Tracing Engine
This paper presents the design and implementation of the OptiX engine, a programmable architecture for interactive parallel ray tracing. By exposing a small set of programmable operations for ray generation, material shading, object intersection, and scene traversal, OptiX enables a diverse set of rendering and non-rendering algorithms.
Reducing Shading on GPUs using Quad-Fragment Merging
Modification of the GPU pipeline to merge fragments generated by rasterization into a single fragment for shading. This optimization significantly decreases the amount of shading work performed when rendering high-quality surfaces represented using micropolygons.
