Detailed Description

Loop structure.

Version
2.0

The m_ucOrientationWithSurface member denotes the orientation of the loop "material left" towards the surface normal. The following values are defined for the m_ucOrientationWithSurface member:

  • 0: Opposite orientations between the loop and the surface
  • 1: Same orientation for the loop and the surface
  • 2: Unknown orientation
