Detailed Description

A concept that checks whether a class has (inherits from) an Face class.

The concept is satisfied when T is a class that instantiates or derives from a Face class having any ParentMesh type and any Component types. The concept checks also that the Face has:

• a BitFlags component;
• VertexPointers or VertexIndices components
• the number of vertices is less than 0 (dynamic size) or at least 3 (static size);
• if the Face has the TriangleBitFlags component, the number of vertices must be 3 (static size);
• all the components tied to the vertex number of the Face are consistent with the number of vertices;

Template Parameters

T	The type to be tested for conformity to the EdgeConcept.
