Member Function Documentation

pointColor()

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

overridevirtual

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.

Since

QGIS 3.26

Implements QgsPreparedPointCloudRendererData.

Definition at line 282 of file qgspointcloudattributebyramprenderer.cpp.

prepareBlock()

bool QgsPointCloudAttributeByRampRendererPreparedData::prepareBlock ( const QgsPointCloudBlock *  block )

overridevirtual

Prepares the renderer for using the specified block.

Returns false if preparation failed.

Implements QgsPreparedPointCloudRendererData.

Definition at line 308 of file qgspointcloudattributebyramprenderer.cpp.

usedAttributes()

QSet< QString > QgsPointCloudAttributeByRampRendererPreparedData::usedAttributes ( ) const

overridevirtual

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

Implements QgsPreparedPointCloudRendererData.
