The left panel can be accessed by clicking the left panel tab:
Figure 42. Collapsed (left) and expanded (right) state of the left panel
The bottom part of this panel has a camera section. By clicking one of the
position buttons, the camera will be instantly placed at one of the three locations,
where the cameras/webcams recording the event will be placed. In addition to this,
three fly-by tours are available, built upon three different 3D Curves in Virtools, and
usage of the Curve Follow BB in Virtools. One more aspect of camera interaction is
that all of the objects composing the world are placed in a Virtools Group, and as a
child script of the camera, the Object Slider BB is used to check for collision of the
camera (within a given radius) with these objects. As this amounts to quite a few
objects (608 to be exact), this could be potential performance handicap for the
application – still, it allows the sensation that the world is physical, and that the user
“bumps” into objects, which is another thing expected of 3D games (although it can
sometimes result with a geometry problem for the camera, in which the space key is
unavoidable).
These represent the most important aspects of camera interaction and 3D
navigation within the world. The top of the left panel, introduced previously, is related
to projector selection (not yet implemented in this version of the application), which
as a user process is discussed in the next subsection.
