name="details" /><hr /><h2>Detailed Description</h2><p>This class can be pickled.</p><p>The QVector3D class represents a vector or vertex in 3D
space.</p>
<p>Vectors are one of the main building blocks of 3D representation
and drawing. They consist of three coordinates, traditionally
called x, y, and z.</p>
<p>The QVector3D class can also be used to represent vertices in 3D
space. We therefore do not need to provide a separate vertex
class.</p>
<p><b>Note:</b> By design values in the QVector3D instance are
stored as <tt>float</tt>. This means that on platforms where the
<tt>qreal</tt> arguments to QVector3D functions are represented by
<tt>double</tt> values, it is possible to lose precision.</p>
