regionSide Class Reference

Determines the 'side' for every face and connected to a singly-connected (through edges) region of faces. Gets set of faces and a list of mesh edges ('fenceEdges') which should not be crossed. Used in splitting a mesh region. More...

Detailed Description

Determines the 'side' for every face and connected to a singly-connected (through edges) region of faces. Gets set of faces and a list of mesh edges ('fenceEdges') which should not be crossed. Used in splitting a mesh region.

Determines:

• For every face on the surface: whether the owner was visited from starting face.
• List of faces using an internal point of the region visitable by edge-face-edge walking from the correct side of the region.
