Triangle String Codes

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

"p"triangulate a planar straight line graph (PLC)
"q"quality mesh generation with no angles smaller than 20 degrees; an alternate minimum angle may be specified after the "q"
"a"impose a maximum triangle area constraint; a fixed area constraint (that applies to every triangle) may be specified after the "a"
"A"assign a regional attribute to each triangle that identifies what segment-bounded region it belongs to
"c"enclose the convex hull with segments
"D"conforming Delaunay: if all triangles in the mesh are to be Delaunay, not just constrained Delaunay, or if you want to ensure that all Voronoi vertices lie within the triangulation
"r"refine a previously generated mesh
"Y"prohibit the insertion of Steiner points on the mesh boundary; if specified twice ("YY"), it prohibits the insertion of Steiner points on any segment, including internal segments
"S"specify the maximum number of added Steiner points
"o2"generate second-order subparametric elements with six nodes each
"C"check the consistency of the final mesh
"Q"quiet: no terminal output except error
