 QgsOffscreen3DEngine ()
 
 ~QgsOffscreen3DEngine () override
 
Qt3DRender::QCamera * camera () override
 Returns pointer to the engine's camera entity.
 
Qt3DRender::QRenderSettings * renderSettings () override
 Returns access to the engine's render settings (the frame graph can be accessed from here)
 
void setClearColor (const QColor &color) override
 Sets background color of the scene.
 
void setFrustumCullingEnabled (bool enabled) override

Detailed Description

3

Off-screen 3D engine implementation. It is useful for recording rendered 3D scenes of arbitrary size.

Note
While the on-screen 3D engine also allows capturing of images, its limitation is that the captured images are of the size of the on-screen window.
Not available in Python bindings
Since
QGIS 3.4
