Interface for mesh data sources

Mesh is a collection of vertices and faces in 2D or 3D space - vertex - XY(Z) point (in the mesh’s coordinate reference system) - faces - sets of vertices forming a closed shape - typically triangles or quadrilaterals

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

New in version 3.2: Methods

faceCount Returns number of faces in the native mesh
populateMesh Populates the mesh vertices and faces
vertexCount Returns number of vertices in the native mesh

Signals
