Detailed Description

Rule-based 3D renderer.

Similar to rule-based 2D renderer and rule-based labeling, it allows specification of rules for 3D symbols.

Warning

This is not considered stable API, and may change in future QGIS releases. It is exposed to the Python bindings as a tech preview only.

Since

QGIS 3.6
