Plane normalization

[AlexanderDalshov]

Hello,

From my point of view plane normalization contains a bug

Plane is defined with normal and distance.
That means, we should find some plane point just by multiplication:

P = N * D

if plane was defined like:
plane1(Vector3f(0.0f, 2.0f, 0.0f), 3.0f);
means, that P = (0, 6, 0)

after plane normalization with current implementation we will have:
plane1Norm (Vec3(0, 1, 0), 1.5);

as a result P1 = Vec3(0, 1, 0) * 1.5 = (0, 1.5, 0)
instead of (0, 6, 0)

I think in normalized method distance should be multiplied by magnitude instead of division.

Plane Plane::Normalized() const
{
	float magnitude = m_normal.Length();

	//Dividing the normal by it's length performs vector normalization.
	//Distance however, must also be divided by the normal's length in
	//order to create an equivalent plane.
-	return Plane(m_normal/magnitude, m_distance/magnitude);
+	return Plane(m_normal/magnitude, m_distance*magnitude);
}
