GPU Rendering of Secondary Effects
In this paper we present an efficient data structure and algorithms for GPU ray tracing of secondary effects like reflections, refractions and shadows. Our method extends previo...

Entropy-based Adaptive Sampling
Ray tracing techniques need supersampling to reduce aliasing and/or noise in the final image. Since not all the pixels in the image require the same number of rays, supersampling...

Dynamic Acceleration Structures for Interactive Ray Tracing
Acceleration structures used for ray tracing have been designed and optimized for efficient traversal of static scenes. As it becomes feasible to do interactive ray tracing of movi...

Interactive Rendering using the Render Cache
Interactive rendering requires rapid visual feedback. The render cache is a new method for achieving this when using high-quality pixel-oriented renderers such as ray tracing that...

Four-dimensional non-linear ray tracing as a visualization tool for gravitational physics
In this paper, general relativistic ray tracing is presented as a tool for gravitational physics. It is shown how standard three-dimensional ray tracing can be extended to allow f...

Path Differentials and Applications
Abstract. Photo-realistic rendering algorithms such as Monte Carlo ray tracing sample individual paths to compute images. Noise and aliasing artefacts are usually reduced by supers...

Interactive ray tracing of free-form surfaces
Even though the speed of software ray tracing has recently been increased to interactive performance even on standard PCs, these systems usually only supported triangles as geomet...

Arbitrary 3D Resolution Discrete Ray Tracing of Implicit Surfaces
A new approach to ray tracing implicit surfaces based on recursive space subdivision is presented in this paper. Interval arithmetic, already used to calculate intersections in ray...
