<hr><a name="_details"></a><h2>Detailed Description</h2>
DrawStuff is a library for rendering simple 3D objects in a virtual environment, for the purposes of demonstrating the features of ODE. It is provided for demonstration purposes and is not intended for production use.<h2><a class="anchor" name="Notes">
Notes</a></h2>
In the virtual world, the z axis is "up" and z=0 is the floor.<p>
The user is able to click+drag in the main window to move the camera: left button - pan and tilt. right button - forward and sideways. left + right button (or middle button) - sideways and up. <hr><h2>Function Documentation</h2>
