Elastic Surface News Today

For the sake of concreteness, let us suppose that we have approximated our potential field by sampling it onto a cubical grid at some fixed resolution.  To get intermediate values, we’ll just interpolate between grid points using the standard trilinear interpolation.  This is like a generalization of Minecraft-style voxel surfaces.  Our goal in this article is to figure out how to extract a mesh of the implicit surface (or zero-crossings of ).  In particular, we’re going to look at...
