C++ (Cpp) Vector2D::lengthSq Examples

Example #1

File: Vector2D.cpp Project: GraphCeppelin/OpenGL-tester

Vector2D	Vector2D :: getRandomVector ( float len )
{
	Vector2D	v;

	for ( ; ; )
	{
		v.x = rnd ();
		v.y = rnd ();

		if ( v.lengthSq () < EPS )
			continue;

		v *= len / v.length ();

		return v;
	}
}

Example #2

File: Vector2D.hpp Project: 7th-Douji/Siv3D-Reference

		constexpr Vector2D projection(const Vector2D& onto) const
		{
			return onto.lengthSq() ? onto * dot(onto) / onto.lengthSq() : Zero;
		}
