Detailed Description

Interface for mesh data sources.

Mesh is a collection of vertices and faces in 2D or 3D space

Base on the underlying data provider/format, whole mesh is either stored in memory or read on demand

Note
The API is considered EXPERIMENTAL and can be changed without a notice
Since
QGIS 3.2
