OdDbPolygonMesh Class

Syntax

C++

class OdDbPolygonMesh : public OdDbEntity;

Description

This class represents PolygonMesh entities in an OdDbDatabase instance.

Remarks

A PolygonMesh entity consists of a list of PolygonMeshVertex (coordinate) vertices describing a M x N array of vertices, defining a set of 3D faces.

M is the number vertices in a row, N is the number of vertices in a column. The first N vertices define the first column, the second N, the second column, etc.

The mesh may be closed in the M and/or N directions. A closed mesh is connected from the last row or column to the first.

Never derive from this class.
