Visualize Surface by Delaunay Triangulator eryar@163.com Abstract. Delaunay Triangulation is the core algorithm for mesh generation. By Delaunay Triangulator you can make a general method to visualize geometry surfaces, so does OpenCascade. The paper
Over the years, I have collected, modified, adapted, adopted or created a number of software packages in FORTRAN. You might be able to use one of these libraries, or a routine or two from a library. The packages are at different levels of completion.
