Returns the list of points of the point cloud according to a zoom level
|

defined by ``maxError`` (in layer coordinates), an extent ``geometry`` in the 2D plane

and a range ``extentZRange`` for z values. The function will try to limit

the number of points returned to ``pointsLimit`` points
|

this function does not handle elevation properties and you need to

change elevation coordinates yourself after returning from the function

virtual QgsGeometry polygonBounds() const;
|
|
%Docstring
|
|
Returns the polygon bounds of the layer. The CRS of the returned geometry will match the provider's :py:func:`~QgsPointCloudDataProvider.crs`.
|
|
|
|
This method will return the best approximation for the actual bounds of points contained in the
|
|
dataset available from the provider's metadata. This may match the bounding box rectangle returned
|
|
by :py:func:`~QgsPointCloudDataProvider.extent`, or for some datasets a "convex hull" style polygon representing a more precise bounds
|
|
will be returned.
|
|
|
|
This method will not attempt to calculate the data bounds, rather it will return only whatever precomputed bounds
|
|
are included in the data source's metadata.

virtual QVariantMap originalMetadata() const;
|

%Docstring
|

Returns a representation of the original metadata included in a point cloud dataset.

This is a free-form dictionary of values, the contents and structure of which will vary by provider and
|
|
dataset.
|
|
%End

virtual QgsPointCloudRenderer *createRenderer( const QVariantMap &configuration = QVariantMap() ) const /Factory/;
|
|
%Docstring
|
|
Creates a new 2D point cloud renderer, using provider backend specific information.
|
|
|
|
The ``configuration`` map can be used to pass provider-specific configuration maps to the provider to
|
|
allow customization of the returned renderer. Support and format of ``configuration`` varies by provider.
|
|
|
|
When called with an empty ``configuration`` map the provider's default renderer will be returned.
|
|
|
|
This method returns a new renderer and the caller takes ownership of the returned object.
|
|
|
|
Only providers which report the CreateRenderer capability will return a 2D renderer. Other
|
|
providers will return ``None``.
