\class QGLTeapot
\brief The QGLTeapot class represents a 3D teapot object.
\since 4.8
\ingroup qt3d
\ingroup qt3d::geometry
The classic 3D "Utah Teapot" was originally drawn by Martin Newell
in 1975. The vertex data was made publicly available by him and
it has been a standard 3D test object ever since.
For more information on the history of the "Utah Teapot", see
Wikipedia, http://en.wikipedia.org/wiki/Utah_teapot.
The following example code uses QGLTeapot to draw a teapot of size
0.5 at the origin:
\code
QGLBuilder builder;
builder << QGLTeapot();
teapot = builder.finalizedSceneNode();
painter.modelViewMatrix().scale(0.5f);
teapot->draw(painter);
\endcode
The QGLTeapot object contains a lot of vertex data once it has
been subdivided into triangles. It is recommended that instances
of this class be created at startup, added to a QGLBuilder,
and then the finalized scene node can be reused over and over.
