quadArea¶

pyvsim.Utils.quadArea(p1, p2, p3, p4)[source]¶

Returns the area of a quadrilateral defined by its edge points. The following assumptions are made:

• All points lie in the same plane
• The quadrilateral is convex

Parameters :	p1, p2, p3, p4 : numpy.ndarray \((N,3)\) Points or list of points defining quadrilaterals
Returns :	result : numpy.ndarray \((N)\) The area of the quadrilaterals

Examples

>>> pts    = np.array([[0,0,0], 
...                    [0,1,0], 
...                    [0,1,1], 
...                    [0,0,1]])
>>> quadArea(pts[0], pts[1], pts[2], pts[3])
