Member Function Documentation

void Vector::Set	(	float	x,
		float	y,
		float	z
	)

Set the x, y and z components of the vector to the given values.

Parameters:

x	vector x-axis value
y	vector y-axis value
z	vector z-axis value

float Vector::LengthSquared

(

)

Returns the squared Euclidean length of the vector.

This is faster than Length() since the square root is not computed.
