QGeometryRenderer

PyQt5.Qt3DRender.QGeometryRenderer

Inherits from QComponent.

Inherited by QConeMesh, QCuboidMesh, QCylinderMesh, QExtrudedTextMesh, QMesh, QPlaneMesh, QSphereMesh, QTorusMesh.

Description

Encapsulates geometry rendering.

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.

Enums

PrimitiveType

The type of the primitive.
