The halfway vector disk for BRDF modeling
Jared Johnson, Michael Ashikhmin, Chris Wyman, Solomon Boulos, Michael Stark, Dave Edwards, Peter Shirley
We present a mathematical framework for enforcing energy conservation in a bidirectional reflectance distribution function (BRDF) by specifying halfway vector distributions in simple two-dimensional domains. Energy-conserving BRDFs can produce...
A semi-Lagrangian contouring method for fluid simulation
Adam W. Bargteil, Tolga G. Goktekin, James F. O'Brien, John A. Strain
In this article, we present a semi-Lagrangian surface tracking method for use with fluid simulations. Our method maintains an explicit polygonal mesh that defines the surface, and an octree data structure that provides both a spatial index for the...
A Bayesian method for probable surface reconstruction and decimation
James R. Diebel, Michael Brünig, Sebastian Thrun
We present a Bayesian technique for the reconstruction and subsequent decimation of 3D surface models from noisy sensor data. The method uses oriented probabilistic models of the measurement noise and combines them with feature-enhancing prior...
Glift: Generic, efficient, random-access GPU data structures
Aaron E. Lefohn, Robert Strzodka, John D. Owens, Joe Kniss, Shubhabrata Sengupta
This article presents Glift, an abstraction and generic template library for defining complex, random-access graphics processor (GPU) data structures. Like modern CPU data structure libraries, Glift enables GPU programmers to separate algorithms from...
Rendering biological iridescences with RGB-based renderers
Brilliant iridescent colors occur on many biological objects. Current RGB-based graphics renderers are not sufficient to simulate such phenomena. This is because biological iridescences are caused by interference or diffraction, which requires...
Salient geometric features for partial shape matching and similarity
Ran Gal, Daniel Cohen-Or
This article introduces a method for partial matching of surfaces represented by triangular meshes. Our method matches surface regions that are numerically and topologically dissimilar, but approximately similar regions. We introduce novel local...
Hierarchical RLE level set: A compact and versatile deformable surface representation
Ola Nilsson, Ken Museth, Ben Houston, Christopher Batty, Michael B. Nielsen
This article introduces the Hierarchical Run-Length Encoded (H-RLE) Level Set data structure. This novel data structure combines the best features of the DT-Grid (of Nielsen and Museth ) and the RLE Sparse Level Set (of Houston et al. )...
