Research:
IMR 2006 On Asymptotically Optimal Meshes by Coordinate Transformation 15th International Meshing Roundtable 2006.


We begin by providing simpler proofs of previously known results in the approximation of functions w.r.t. gradient error and show constructively that a closed-form solution exists for them. We then show that the transformational method for obtaining meshes, as is, cannot produce asymptotically optimal meshes for general inputs. We discuss possible variations of the problem that may allow for some forms of optimality to be proved.
IMR 2006 Surface Remeshing in Arbitrary Codimensions [ pdf | slides ] Pacific Graphics 2006.


We remesh in three simple stages. First the input surface is mapped to a (possibly high-dimensional) space; then it is uniformly remeshed in that space; and finally brought back to the original space. The resulting mesh derives its properties from the mapping, and can be computed efficiently.
