C++ (Cpp) Point2::distance Beispiele

Beispiel #1

{
	double x1 = p1.x;
	double x2 = p2.x;
	double y1 = p1.y;
	double y2 = p2.y;

	double x0 = p.x;
	double y0 = p.y;

	double den = fabs((y2 - y1)*x0 - (x2-x1)*y0 + x2*y1-y2*x1);
	double num = sqrt((y2-y1)*(y2-y1) + (x2-x1)*(x2-x1));


	double linedist = den / num;

	double p1_dist = p1.distance(p);
	double p2_dist = p2.distance(p);

		return std::numeric_limits<double>::infinity();

	if (p2_dist > edge_len)
