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 263 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 289 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.

Definition at line 284 of file qgspointcloudattributebyramprenderer.cpp.
