A class containing utility functions for shapes.
Note that these are all linear functions so it is neccessary to calculate separately for x, y (and z, w if present) components of a vector.
contour -- 2D polygon. An array of v3d.Vector2()
Calculate area of a (2D) contour polygon.
pts -- points defining a 2D polygon
Note that this is a linear function so it is neccessary to calculate separately for x, y components of a polygon.
Used internally by Path, ExtrudeGeometry and ShapeGeometry.
contour -- 2D polygon.
holes -- array of holes
Used internally by ExtrudeGeometry and ShapeGeometry to calculate faces in shapes with holes.
