QgsMeshDataSourceInterface class
Interface for mesh data sources.
Contents
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
Derived classes
- class QgsMeshDataProvider
- Base class for providing data for QgsMeshLayer.
Constructors, destructors, conversion operators
- ~QgsMeshDataSourceInterface() defaulted virtual
- Dtor.
Public functions
- auto faceCount() const -> int pure virtual
- Returns number of faces in the native mesh.
- void populateMesh(QgsMesh* mesh) const pure virtual
- Populates the mesh vertices and faces.
- auto vertexCount() const -> int pure virtual
- Returns number of vertices in the native mesh.
