C++ (Cpp) wedgeProduct Exemples

Exemple #1

// Computes area of quads that are possibly non-rectangular. Can be easily extended to polygons.
static inline float quadArea(const FloatQuad& quad)
{
    return fabs(0.5 * (wedgeProduct(quad.p1(), quad.p2()) +
                       wedgeProduct(quad.p2(), quad.p3()) +
                       wedgeProduct(quad.p3(), quad.p4()) +
                       wedgeProduct(quad.p4(), quad.p1())));
}
