Improving Chen & Han's Algorithm on the Discrete Geodesic Problem
This paper discusses the “single source, any vertex" shortest-path problem. The main aim of this research is to show how to filter out useless windows using current estimates of the distances to the vertices and to explore another technique, involving maintaining a priority queue.
Feature-Preserving Triangular Geometry Images for Level-of-Detail Representation of Static and Skinned Meshes
This paper introduces triangular-chart geometry images as the GPU-side representation for view-dependent level-of-detail rendering of skinned dynamic meshes, with support for feature preservation. It results in a 10-fold improvement in fidelity compared to quad-chart geometry images.
Controllable Conformal Maps for Shape Deformation and Interpolation
A novel 2D shape-deformation system that generates conformal maps, yet provides the user with a large degree of control over the result. For example, it allows singularities at user-specified boundary points, so true "bends” can be introduced into the deformation.
Accurate Multidimensional Poisson-Disk Sampling
This paper presents an accurate and efficient sampling method in n-dimensional space based on a Poisson-disk distribution. The method is accurate because it obeys the statistical properties of the dart-throwing algorithm. It is efficient because it employs a spatial subdivision structure to signal regions of empty space.
Multi-Class Blue Noise Sampling
An extension of traditional single-class algorithms in which each class and their unions exhibit blue-noise properties. The paper presents two flavors of methods that offer explicit controls for sample count or spacing, based on the notion of hard/soft disks.
