QgsPreparedPointCloudRendererData::~QgsPreparedPointCloudRendererData ( )

virtualdefault

virtual QColor QgsPreparedPointCloudRendererData::pointColor	(	const QgsPointCloudBlock *	block,
		int	i,
		double	z
	)

pure virtual

An optimised method of retrieving the color of a point from a point cloud block.

Before calling this method prepareBlock() must be called for each incoming point cloud block.

virtual bool QgsPreparedPointCloudRendererData::prepareBlock ( const QgsPointCloudBlock * block )

pure virtual

Prepares the renderer for using the specified block.

Returns false if preparation failed.

virtual QSet< QString > QgsPreparedPointCloudRendererData::usedAttributes ( ) const

pure virtual

Returns the set of attributes used by the prepared point cloud renderer.
