16th Eurographics Symposium on Rendering Techniques, EGSR 2005
作者: Li, Hongsong Pellacini, Fabio Torrance, Kenneth Program of Computer Graphics Rhodes Hall Cornell University IthacaNY14853 United States
Subsurface scattering is a fundamental aspect of surface appearance responsible for the characteristic look of many materials. Monte Carlo path tracing techniques can be employed with high accuracy to simulate the sca... 详细信息

15th Eurographics Workshop on Rendering Techniques, EGSR 2004
作者: Ramanarayanan, G. Bala, K. Walter, B. Department of Computer Science Cornell University IthacaNY United States Program of Computer Graphics Cornell University IthacaNY United States
This paper introduces feature-based textures, a new image representation that combines features and samples for high-quality texture mapping. Features identify boundaries within an image where samples change discontin... 详细信息

21st Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1994
作者: Arvo, James Program of Computer Graphics Cornell University 580 Engineering and Theory Center Building IthacaNY14853 United States
The irradiance at a point on a surface due to a polyhedral source of uniform brightness is given by a well-known analytic formula. In this paper we derive the corresponding analytic expression for the irradiance Jacob... 详细信息

24th Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1997
作者: Ferwerda, James A. Shirley, Peter Pattanaik, Sumanta N. Greenberg, Donald P. Program of Computer Graphics Cornell University 580 Rhodes Hall Ithaca United States University of Utah United States
In this paper we develop a computational model of visual masking based on psychophysical data. The model predicts how the presence of one visual pattern aects the detectability of another. The model allows us to choos... 详细信息

21st Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1994
作者: Arvo, James Torrance, Kenneth Smits, Brian Program of Computer Graphics Cornell University 580 Engineering and Theory Center Building IthacaNY14853 United States
In this paper we identify sources of error in global illumination algorithms and derive bounds for each distinct category. Errors arise from three sources: inaccuracies in the boundary data, discretization, and comput... 详细信息

Effects of structural imperfections on constant-feedback-gain control of a spatial structure
收藏 引用
Computing Systems in Engineering 1990年 第2-4期1卷 601-606页
作者: Aubert, B.H. Abel, J.F. Lu, J. Thorp, J.S. School of Civil and Environmental Engineering Program of Computer Graphics Cornell University Ithaca NY 14853 United States School of Electrical Engineering Cornell University Ithaca NY 14853 United States
The numerical sensitivity of a constant-feedback-gains controller to random structural imperfections is examined using the results of a series of finite element analyses. The basic finite element model, which uses lin...

23rd Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1996
作者: Ferwerda, James A. Pattanaik, Sumanta N. Shirley, Peter Greenberg, Donald P. Program of Computer Graphics 580 Frank H. T. Rhodes Hall Cornell University IthacaNY14853 United States
In this paper we develop a computational model of visual adaptation for realistic image synthesis based on psychophysical experiments. The model captures the changes in threshold visibility, color appearance, visual a... 详细信息

8th Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1981
作者: Cook, Robert L. Torrance, Kenneth E. Program of Computer Graphics Cornell University IthacaNY14853 United States Sibley School of Mechanical and Aerospace Engineering Cornell University IthacaNY14853 United States
This paper presents a new reflectance model for rendering computer synthesized images. The model accounts for the relative brightness of different materials and light sources in the same scene. It describes the direct... 详细信息

Frontiers of Massively Parallel Computation
作者: P. Kochevar Program of Computer Graphics Cornell University USA
A computer graphics algorithm for simulating the propagation of light and its interaction with matter on a massively parallel computer is presented. This algorithm, called the tagged shooting method, is designed for a... 详细信息
