TetGen String Codes

This describes the string codes (command switches) needed by TetGenLink to compute various computational geometry tasks.

"p"tetrahedralizes a piecewise linear complex (PLC)
"q"quality mesh generation; a minimum radius-edge ratio may be specified (default 2.0)
"a"applies a maximum tetrahedron volume constraint
"A"assigns attributes to identify tetrahedra in certain regions
"r"reconstructs/refines a previously generated mesh
"Y"suppresses boundary facets/segments splitting
"i"inserts a list of additional points into mesh
"M"does not merge coplanar facets
"T"sets a tolerance for coplanar test (default 10-8)
