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
