Efficient Optimization of Common Base Domains for Cross Parameterization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Tsz-Ho Kwok,Yunbo Zhang,Charlie C.L. Wang
Issue Date:October 2012
pp. 1678-1692
Given a set of corresponding user-specified anchor points on a pair of models having similar features and topologies, the cross parameterization technique can establish a bijective mapping constrained by the anchor points. In this paper, we present an effi...
Approximate Boolean Operations on Large Polyhedral Solids with Partial Mesh Reconstruction
Found in: IEEE Transactions on Visualization and Computer Graphics
By Charlie C.L. Wang
Issue Date:June 2011
pp. 836-849
We present a new approach to compute the approximate Boolean operations of two freeform polygonal mesh solids efficiently with the help of Layered Depth Images (LDIs). After applying the LDI sampling-based membership classification, the most challenging pa...
Interactive Control of Large-Crowd Navigation in Virtual Environments Using Vector Fields
Found in: IEEE Computer Graphics and Applications
By Xiaogang Jin, Jiayi Xu, Charlie C.L. Wang, Shengsheng Huang, Jun Zhang
Issue Date:November 2008
pp. 37-46
Providing interactive control is a hot topic in crowd-navigation research. Here, the authors propose a simple but effective way for authoring a crowd scene. With their governing tool, users can easily drive the flow of crowds by sketching velocities on anc...
Efficient and Stable Simulation of Cloth Undergoing Large Rotations
Found in: Computing in Science and Engineering
By Chuan Zhou, Xiaogang Jin, Charlie C.L. Wang
Issue Date:July 2008
pp. 30-40
The semi-implicit integration scheme is often used to simulate cloth animation because of its high stability and efficiency. However, it gives notable vibrations because of linear approximation in large rotations, which always occur in cloth simulations. H...
A least-norm approach to flattenable mesh surface processing
Found in: Shape Modeling and Applications, International Conference on
By Charlie C.L. Wang
Issue Date:June 2008
pp. 131-138
Following the definition of developable surface in differential geometry, the flattenable mesh surface, a special type of piecewise-linear surface, inherits the good property of developable surface about having an isometric map from its 3D shape to a corre...
Bilateral Recovering of Sharp Edges on Feature-Insensitive Sampled Meshes
Found in: IEEE Transactions on Visualization and Computer Graphics
By Charlie C.L. Wang
Issue Date:July 2006
pp. 629-639
<p><b>Abstract</b>—A variety of computer graphics applications sample surfaces of 3D shapes in a regular grid without making the sampling rate adaptive to the surface curvature or sharp features. Triangular meshes that interpolate or appr...
