Examiner Viewer
The “Examiner” viewer allows free movement within three-dimensional space.
The camera can be rotated about any desired axis around a central rotation
point. The method of control is intuitive and matches an observer’s natural
movements. For example, given that a sphere contains the scene and the center
of the sphere is the rotation point. The analogy is that you simply need to place
a hand on the surface of the sphere in order to move it. Any desired viewing
direction is set in this manner.
The Examiner Viewer lets you “walk” through the scene. Figure 2.2 and Figure
2.3 show sample scenes (.

scene in Figure 2.3 also contains “animation” data, causing the Animation slider
to appear.
