On Particle Path Generation Based on Quadrilinear Interpolation and Bernstein-Bézier Polynomials
Particle path computation in unsteady 3D vector fields given in discrete, structured form (i.e., as a hexahedral curvilinear grid) requires the local approximation of the vector field and the path. Quadrilinear interpolation and Bernstein-Bezier ...
Collision Detection for Interactive Graphics Applications
Collision detection and response are important for interactive graphics applications such as vehicle simulators and virtual reality. Unfortunately, previous collision detection algorithms are too slow for interactive use. The paper presents a new ...
Line Art Rendering via a Coverage of Isoparametric Curves
A line art nonphotorealistic rendering scheme of scenes composed of freeform surfaces is presented. A freeform surface coverage is constructed using a set of isoparametric curves. The density of the isoparametric curves is set to be a function of the ...
A Unified Hierarchical Algorithm for Global Illumination with Scattering Volumes and Object Clusters
The paper presents a new radiosity algorithm that allows the simultaneous computation of energy exchanges between surface elements, scattering volume distributions, and groups of surfaces, or object clusters. The new technique is based on a hierarchical ...

Augmented reality entails the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed in such a way that they blend ...
Dynamic Color Quantization of Video Sequences
We present an efficient algorithm for dynamic adaptive color quantization of 24 bit image (video) sequences, important in multimedia applications. Besides producing hi fidelity 8 bit imagery, our algorithm runs with minimal computational cost and the ...
