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 |
