Member Function Documentation

◆ pointColor()

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.

Since
QGIS 3.26

Implemented in QgsPointCloudAttributeByRampRendererPreparedData, QgsPointCloudClassifiedRendererPreparedData, and QgsPointCloudRgbRendererPreparedData.

◆ prepareBlock()

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

Prepares the renderer for using the specified block.

Returns false if preparation failed.

Implemented in QgsPointCloudAttributeByRampRendererPreparedData, QgsPointCloudClassifiedRendererPreparedData, and QgsPointCloudRgbRendererPreparedData.

◆ usedAttributes()

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

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

Implemented in QgsPointCloudAttributeByRampRendererPreparedData, QgsPointCloudClassifiedRendererPreparedData, and QgsPointCloudRgbRendererPreparedData.
