This lab makes it easy to see the difference between the scene's global coordinate system (X-Y-Z) and a local coordinate system (fwd-up). The local coordinate system may apply to objects at any location in a hierarchy of WTGroups. In this case, it applies to the WTGroup that holds the model of your choice.
Drag the mouse around the scene to pivot the model about the global X- and Y- axes. Right-button-drag to rotate the model about the global Z-axis. Press - or + to scale the model. Use the arrow keys to pan the camera around the scene. Press the button to reorient the model into the default orientation. This is the orientation of a model when it is first placed in the scene if no other orientation is specified.
