Detailed Description
This is an extension of Triangulator to handle polygons with three- dimensional points.
It assumes all of the points lie in a single plane, and internally projects the supplied points into 2-D for passing to the underlying Triangulator object.

Member Function Documentation
◆ add_vertex() [1/2]
| int Triangulator3::add_vertex | ( | const LPoint3d & | point | ) |
Adds a new vertex to the vertex pool.
Returns the vertex index number.
Definition at line 39 of file triangulator3.cxx.
Referenced by add_vertex().
◆ add_vertex() [2/2]
|
inline |
Adds a new vertex to the vertex pool.
Returns the vertex index number.
Definition at line 18 of file triangulator3.I.
References add_vertex().
◆ clear()
| void Triangulator3::clear | ( | ) |
Removes all vertices and polygon specifications from the Triangulator, and prepares it to start over.
Definition at line 29 of file triangulator3.cxx.
References Triangulator::clear().
◆ triangulate()
| void Triangulator3::triangulate | ( | ) |
Does the work of triangulating the specified polygon.
After this call, you may retrieve the new triangles one at a time by iterating through get_triangle_v0/1/2().
Definition at line 51 of file triangulator3.cxx.
Member Data Documentation
◆ get_num_vertices
|
inline |
Returns the number of vertices in the pool.
Note that the Triangulator might append new vertices, in addition to those added by the user, if any of the polygon is self-intersecting, or if any of the holes intersect some part of the polygon edges.
Definition at line 38 of file triangulator3.h.
◆ get_plane
|
inline |
Returns the plane of the polygon.
This is only available after calling triangulate().
Definition at line 44 of file triangulator3.h.
◆ get_vertex
|
inline |
Returns the nth vertex.
Definition at line 38 of file triangulator3.h.
