===Fields===

{| class="wikitable sortable" border=1
! 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.
|-

===Functions===

{| class="wikitable sortable" border=1
! Return Type !! Function Name !! Parameters !! Description
|-
| float || GetElement || uint64 alIdx, <br />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, <br />float, <br />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.

<syntaxhighlight lang="c++">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);</syntaxhighlight>
