9404959 Salesin Global illumination, which simulates the interreflection of light between surfaces, is one of the most fundamental problems in computer graphics, with a wide variety of applications. During the award period, the research will be focused on three critical aspects of the global illumination problem: (1) Controlled-precision methods -- Global illumination algorithms that compute tight bounds on the error simultaneously with the simulation will be developed. These algorithms will be able to direct their computational efforts into regions where the error is largest, resulting in improvements in both speed and accuracy. (2) Improving discontinuity meshing -- Incremental discontinuity-meshing algorithms in which only numerically or visually significant discontinuities are ever computed will be investigated. Discontinuity meshing techniques are planned to be extended to curved surfaces. (3) Smooth wavelet bases for radiosity -- The discontinuity meshing will be combined with the use of smooth wavelet bases in order to provide accurate, yet sparse, representations of the light transport between the surfaces of an environment. ***

9404959销售 全局光照是模拟物体表面间光的相互反射，是计算机图形学中最基本的问题之一，有着广泛的应用。 在获奖期间，研究将集中在全球照明问题的三个关键方面： (1)控制精度的方法-将开发在模拟的同时计算误差严格界限的全局照明算法。 这些算法将能够将其计算工作导向误差最大的区域，从而提高速度和准确性。 (2)改进不连续性网格-增量不连续性网格算法，其中只有数值或视觉上显着的不连续性计算将被调查。 不连续网格技术计划扩展到曲面。 (3)用于辐射度的平滑小波基--不连续网格化将与平滑小波基的使用相结合，以便提供环境表面之间光传输的准确但稀疏的表示。 ***
