class QgsTessellator
|
|
{
|
|
%Docstring(signature="appended")
|
|
Class that takes care of tessellation of 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.

Creates tessellator with a specified origin point of the world (in map coordinates)

|
|
%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.
