SurfacePolygonTriangulatorInitializer#
- class ansys.stk.core.graphics.SurfacePolygonTriangulatorInitializer#
Triangulates a polygon, with an optional hole, on a central body, into a triangle mesh and a surrounding boundary. The mesh is commonly visualized with the triangle mesh primitive or surface mesh primitive…
Overview#
Compute the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions. This is equivalent to calling Compute with an altitude of 0, a granularity of 1 degree, and a positionsWindingOrder of compute. |
|
For convenience. Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified cartographic positions. This is equivalent to converting each position in positions to cartesian and calling Compute. |
