Fields

Field Name Type Description
x float The x value of the vector.
y float The y value of the vector.
z float The z value of the vector.
w float The w value of the vector.

Functions

Return Type Function Name Parameters Description
float GetElement uint64 alIdx,
const
Gets the value at the given index. (Indices 0, 1, 2, and 3 are equal to x, y, z, and w respectively.)
void SetElement uint64 alIdx,
float,
const
Sets the value at the given index to the given value. (Indices 0, 1, 2, and 3 are equal to x, y, z, and w respectively.)
float SqrLength const Returns the length-squared of this vector.
float Length const Returns the length of this vector.
float Normalize Returns the normalization factor for this vector. (See Remarks.)

Remarks

A normalized vector is a vector whose length is equal to one, otherwise known as a unit vector. To convert a vector into a unit vector, get the normalization factor by calling the Normalize function, then divide each of the vector's x, y, z, and w coordinates by that factor.

cVector4f vBaseVector(2.0, 5.0, 3.0, 4.0);
float fNormFactor = vBaseVector.Normalize();
cVector3f vNormalizedVector(vBaseVector.x / fNormFactor, 
                            vBaseVector.y / fNormFactor, 
                            vBaseVector.z / fNormFactor,
                            vBaseVector.w / fNormFactor);
