sumTriangleAreasPerpendicularToUpVector MethodStatic
Sum areas of triangles from points[0] to each far edge, as viewed with upVector pointing up.
- Consider triangles from points[0] to each edge.
- Sum the areas perpendicular to the upVector.
- If the upVector is near-zero length, a simple z vector is used.
