Description

This slide shows the latest result of a new multiresolution isosurface extraction algorithm known as Adaptive Skeleton Climbing. It directly extracts isosurfaces in multiresolution from the volume data without going through any postprocessing mesh reduction. The coarser mesh is generated in a time comparable to the time marching cubes used to generate the finest resolution mesh. This slide demonstrates the extracted isosurfaces of a mathematical knot in four resolutions. The mesh coarseness increases in the following order: top left, top right, bottom left and finally bottom right. Note how the algorithm fits large triangles to smooth regions and small triangles to regions with complex geometry in order to preserve the details.

Hardware: Any UNIX platform.
Software: Adaptive Skeleton Climbing isosurface extraction package
