DelIso software can mesh an Iso-surface from volume data with Delaunay triangles that have bounded aspect ratio. Currently it can handle 256x256x256 volume data on a state of the art PC in 10-15 minutes. It maintains the topology and approximates the geometry of the original surface. It works on the principle of Delaunay refinement that finds points on the given surface till the topology and geometry are recovered and then mesh them with Delaunay triangles restricted to the surface. The assumption about the input is that the actual Isosurface does not have sharp edges and sharp corners. In these cases the algorithm may produce some artifacts.The software is based on recent results described in the paper given below.
Codes are available for Linux, and Windows.
