To convert a vector into a unit vector, get the normalization factor by calling the <code>Normalize</code> function, then divide each of the vector's x, y, z, and w coordinates by that factor. </p> <pre class="code =c++">cVector4f vBaseVector<span class="br0">(</span><span class="nu16">2.0</span><span class="sy0">,</span> <span class="nu16">5.0</span><span class="sy0">,</span> <span class="nu16">3.0</span><span class="sy0">,</span> <span class="nu16">4.0</span><span class="br0">)</span><span class="sy0">;</span> <span class="kw4">float</span> fNormFactor <span class="sy0">=</span> vBaseVector.<span class="me1">Normalize</span><span class="br0">(</span><span class="br0">)</span><span class="sy0">;</span> cVector3f vNormalizedVector<span class="br0">(</span>vBaseVector.<span class="me1">x</span> <span class="sy0">/</span> fNormFactor<span class="sy0">,</span> vBaseVector.<span class="me1">y</span> <span class="sy0">/</span> fNormFactor<span class="sy0">,</span> vBaseVector.<span class="me1">z</span> <span class="sy0">/</span> fNormFactor<span class="sy0">,</span> vBaseVector.<span class="me1">w</span> <span class="sy0">/</span> fNormFactor<span class="br0">)</span><span class="sy0">;</span> </pre><p> </p> </div>
