<div class="RenoIncludeDIV"><div class="RenoAutoDIV"><h3>boost/qvm/quat_traits_array.hpp</h3>
</div>
<p>This header introduces specializations of the <i><span class="RenoLink"><a href="quat_traits.html">quat_traits</a></span></i>, <i><span class="RenoLink"><a href="deduce_quat.html">deduce_quat</a></span></i> and <i><span class="RenoLink"><a href="deduce_quat2.html">deduce_quat2</a></span></i> templates that make it possible to pass C arrays of size 4 to any Boost QVM function that takes a quaternion.</p>
<p>For example, after <i>#include &lt;<span class="RenoLink">boost/qvm/quat_traits_array.hpp</span>&gt;</i>, to compute the dot product of two float C arrays of size 4 interpreted as quaternions, you could use:</p>
<pre>float a[4], b[4];
float dp = <span class="RenoLink"><a href="dot_quat_quat_.html">dot</a></span>(a,b);</pre>
<p>To use Boost QVM operator overloads, at least one of the arguments must not be of a built-in type; for example you can't multiply a C array quaternion by a scalar by using <i><span class="RenoLink"><a href="operator_mul_eq_quat_scalar_.html">operator*=</a></span></i> directly. Use <i><span class="RenoLink"><a href="qref.html">qref</a></span></i> to work around this issue:</p>
<pre>float a[4];
<span class="RenoLink"><a href="qref.html">qref</a></span>(a) <span class="RenoLink"><a href="operator_mul_eq_quat_scalar_.html">*=</a></span> 42;</pre>
