Archicad的三角剖分的api用起来还是比较麻烦的。主要是API文档有问题，没有案例。

这里给出一个样例：

一下一个五角形，注意起点和终点是同一个点。最后打印的是顶点的索引。

const double px[6] = { 0,1,3,4,2,0 };const double py[6] = { 1,0,0,1,2,1 };const double pz[6] = { 0,0,0,0,0,0 };bool result;const short mask[6] = {0,0,0,0,0,-1};Int32 ncoord = 6;const double meshLevelx[1] = {2};const double meshLevely[1] = {1};const double meshLevelz[1] = { 0 };Int32 numMeshLevelPts = 1;const Int32	 subLineEnds=0;Int32 numSubLineEnds = 0;Geometry::DelaunayTriangulation delaunayTriangulation(px, py,pz,mask, ncoord,meshLevelx,meshLevely,meshLevelz,numMeshLevelPts,&subLineEnds, numSubLineEnds);GS::Array<Geometry::TDTri> tris;result=delaunayTriangulation.TDTriangulate(tris);if (result){DBPrintf("meshes number is %d", tris.GetSize());for(Int32 i=0;i < tris.GetSize();i++){Geometry::TDTri tri;tri=tris.Get(i);DBPrintf("v1: %d,v2:%d,v3:%d \n", tri.v1.index, tri.v2.index, tri.v3.index);}}
