class QgsTessellator
{
%Docstring
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.

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

%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.

.. versionadded:: 3.10
%End

    void addPolygon( const QgsPolygon &polygon, float extrusionHeight );
%Docstring
Tessellates a triangle and adds its vertex entries to the output data array
%End

    QVector<float> data() const;
%Docstring
Returns array of triangle vertex data

Vertice coordinates are stored as (x, z, -y)
%End

    int dataVerticesCount() const;
%Docstring
Returns the number of vertices stored in the output data array
%End

    int stride() const;
%Docstring
Returns size of one vertex entry in bytes
%End


    float zMinimum() const;
%Docstring
Returns minimal Z value of the data (in world coordinates)

.. versionadded:: 3.12
%End

    float zMaximum() const;
%Docstring
Returns maximal Z value of the data (in world coordinates)
