Detailed Description

A QGeometryRenderer holds all the information necessary to draw a QGeometry . A QGeometry holds the coordinates of the geometry data - QGeometryRenderer specifies how to interpret that data.

class PySide2.Qt3DRender.Qt3DRender.QGeometryRenderer([parent=None])

param parent

QNode

Constructs a new QGeometryRenderer with parent .
