Mesh generation is a field in itself, which is treated much more fully on some other Web pages. Robert Schneiders mesh generation page, in particular, has links to free and commercial software. There is a nice (although clearly incomplete) survey of three dimensional mesh generators at from NASA.
There are a bunch of other triangulation programs on these pages (triangulations are also known as unstructured meshes), some of which produce high-quality triangulations suitable for finite element methods.

For a longer description and links to the software itself, go to the Web page . The code is also available via ftp.
Meshing code by
Paul Chew, of Cornell University.
Here's more info and a pointer to the code.
A MATLAB implementation of a circle-packing based 2-D mesh generator, with interactive input only, is in another ftp directory.
