|
|
Tessellates polygons into triangles.
|
|
|
|
It is expected that client code will create the tessellator object, then
|
|
repeatedly call :py:func:`~addPolygon` method that will generate
|
|
triangles, and finally call :py:func:`~data` to get final vertex data.
|
|
|
|
Optionally provides extrusion by adding triangles that serve as walls
|
|
when extrusion height is non-zero.

%Docstring
|
|
Creates tessellator with a specified ``bounds`` of input geometry
|
|
coordinates. This constructor allows the tessellator to map input
|
|
coordinates to a desirable range for numerical stability during
|
|
calculations.
|
|
|
|
If ``noZ`` is ``True``, then a 2-dimensional tessellation only will be
|
|
performed and all z coordinates will be ignored.
