Hierarchical RLE level set: A compact and versatile deformable surface representation
Houston, Ben; Nielsen, Michael B.; Batty, Christopher; Nilsson, Ola; Museth, Ken (Association for Computing Machinery, 2006-01)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 [2004]) and the RLE Sparse Level Set ... -
A simple finite volume method for adaptive viscous liquids
Batty, Christopher; Houston, Ben (Association for Computing Machinery, 2011-08)We present the first spatially adaptive Eulerian fluid animation method to support challenging viscous liquid effects such as folding, coiling, and variable viscosity. We propose a tetrahedral node-based embedded finite ... -
Tetrahedral Embedded Boundary Methods for Accurate and Flexible Adaptive Fluids
Batty, Christopher; Xenos, Stefan; Houston, Ben (Wiley, 2010-05)When simulating fluids, tetrahedral methods provide flexibility and ease of adaptivity that Cartesian grids find difficult to match. However, this approach has so far been limited by two conflicting requirements. First, ...
