Detailed Description

MeshViz Abstract interface to write unstructured surface mesh topology.

This interface is used by the existing tessellator instances (see MiTessellator) to write the topology of the tessellated surface meshes. It is designed to allow the application to implement its own tessellator class.

Member Function Documentation

◆ addPolygon()

virtual void MeWSurfaceTopologyExplicitI::addPolygon ( size_t  numNodes,
const size_t *  nodeIds 
)
pure virtual

Add a new tessellated surface cell in the topology.

For instance if the tessellator builds the tessellated mesh using always triangles, this method is called by giving the 3 node ids for each triangle of the tessellation.

Parameters
[in]numNodesNumber of nodes in the tessellated surface cell.
[in]nodeIdsList of nodes id in the tessellated surface cell.
