geos.GEOSDelaunayTriangulation ⇒ number ⏏
Computes a Delaunay triangulation of the vertices of the given geometry.
Kind: Exported member
Returns: number - A pointer to the geometry representing the Delaunay triangulation. Returns NULL on exception.
| Param | Type | Description |
|---|---|---|
| g | number | The geometry pointer whose vertices to triangulate. |
| tolerance | number | The snapping tolerance to use for improved robustness. A tolerance of 0.0 specifies that no snapping will take place. |
| onlyEdges | number | If non-zero, only the edges of the triangulation will be returned, forming a multilinestring. If zero, the triangles will be returned as a collection of polygons. |
