Represents a indexed point cloud node in octree.
Collection of point cloud attributes.
Base class for handling loading QgsPointCloudBlock asynchronously.
QString errorStr()
Returns the error message string of the request.
QgsPointCloudBlockRequest(const IndexedPointCloudNode &node, const QString &Uri, const QString &dataType, const QgsPointCloudAttributeCollection &attributes, const QgsPointCloudAttributeCollection &requestedAttributes, const QgsVector3D &scale, const QgsVector3D &offset)
QgsPointCloudBlockRequest constructor Note: It is the responsablitiy of the caller to delete the bloc...
QgsPointCloudBlock * block()
Returns the requested block.
void finished()
Emitted when the request processing has finished.
Base class for storing raw data from point cloud nodes.
