The iFaceVertexMesh abstract interface class is key to PathEngine's
content processing functionality.
Classes derived from this interface are built by application developers to wrap application and platform specific geometry representations and to enable PathEngine's content processing to operate directly on these content representations.
Face/vertex representations do not generally provide a way to directly specify connectivity between
edges in pairs of faces.
This will be determined by PathEngine's content processing functionality based on vertex shared between faces - edges that share the same two vertices (but in reverse order) are assumed to be connected.
An example face vertex mesh wrapper class can be found here.
