Notes on Adaptive Quadrature on the Hemisphere

This report discusses several issues that arise when integrating field radiance functions on the hemisphere. Rather than representing new work, it is an expression of what issues underly our current research strategy for scenes that contain specular surfaces. It outlines several basic practical concerns, and identifies problems in adaptive sampling strategy that remain unresolved. It also provi...

Parallel Globally Adaptive Quadrature on the KSR

New algorithms for parallel one-dimensional globally adaptive quadrature are developed. The algorithms are implemented on a Kendall Square Research KSR-1 parallel computer and numerical results are presented. The most successful algorithm gives signiicant speedups on a range of hard problems, including ones with singular integrands.

On-the-Fly Adaptive Subdivision Terrain

In this paper we present a method to achieve interactive rendering of smooth terrain based on coarse data. Therefore we use adaptive subdivision surfaces which are calculated on the fly by using information from the directed edge based mesh of the previously rendered frame and throwing away triangles not used any longer. This way we are able to gain fast, high quality meshes which are refined d...
