Ray tracing deformable scenes using dynamic bounding volume hierarchies

I. Wald, S. Boulos, P. Shirley
Mathematics, Computer Science
TOGS
2007

The most significant deficiency of most of today's interactive ray tracers is that they are restricted to static walkthroughs. Expand

An Anisotropic Phong BRDF Model

M. Ashikhmin, P. Shirley
Computer Science
J. Graphics, GPU, & Game Tools
1 January 2000

We present a BRDF model that combines several advantages of the various empirical models currently in use. Expand

A microfacet-based BRDF generator

M. Ashikhmin, Simon Premoze, P. Shirley
Computer Science
SIGGRAPH
1 July 2000

A method is presented that takes as an input a 2D microfacet orientation distribution and produces a 4D bidirectional reflectance distribution function (BRDF). Expand

A polygonal approximation to direct scalar volume rendering

P. Shirley, A. Tuchman
Computer Science
SIGGRAPH
1 November 1990

A method is presented that approximates tetrahedral volume cells with hardware renderable transparent triangles. Expand

A practical analytic model for daylight

A. J. Preetham, P. Shirley, B. Smits
Computer Science
SIGGRAPH '99
1 July 1999

We present an inexpensive analytic model that approximates full spectrum daylight and skylight for various atmospheric conditions. Expand

A model of visual adaptation for realistic image synthesis

J. Ferwerda, S. Pattanaik, P. Shirley, D. P. Greenberg
Computer Science
SIGGRAPH
1 August 1996

We develop a model that includes the effects of adaptation on threshold visibility, color appearance, visual acuity, and changes in visual sensitivity over time. Expand

Spatially Nonuniform Scaling Functions for High Contrast Images

K. Chiu, M. Herf, P. Shirley, S. Swamy, C. Wang, Kurt J. Zimmerman
Mathematics
1993

An algorithm is presented that scales the pixel intensities of a computer generated greyscale image so that they are all displayable on a standard CRT. This scaling is spatially nonuniform over the… Expand
