Direct Ray Tracing of Displacement Mapped Triangles
We present an algorithm for ray tracing displacement maps that requires no additional storage over the base model. Displacement maps are rarely used in ray tracing due to the cost...

Convolution surfaces
Smoothly blended articulated models are often difficult to construct using current techniques. Our solution in this paper is to extend the surfaces introduced by Blinn [Blinn 1982...

Free Surface Lattice-Boltzmann fluid simulations with and without level sets
We present two variants of free surface LatticeBoltzmann fluid simulations for the animation of liquids in computer graphics. The LatticeBoltzmann method is an attractive alternat...

Piecewise Linear Approximation of Signed Distance Fields
The signed distance field of a surface can effectively support many geometry processing tasks such as decimation, smoothing, and Boolean operations since it provides efficient a...

Constructing A-spline weight functions for stable WEB-spline finite element methods
Whereas traditional finite element methods use meshes to define domain geometry, weighted extended B-spline finite element methods rely on a weight function. A weight function is ...
