QD3D 70 - Finding The Center Of A Model (11-July-97)

Q How can I find the center of a model, so I can position the camera to completely display the model (much like the 'home' camera position in the Simple Viewer)?

A Use the Q3View_StartBoundingBox and Q3View_EndBoundingBox routines to compute an object's bounding box. Next, use the data in the TQ3BoundingBox structure returned by Q3View_EndBoundingBox to compute the center of the object.
