Notes
Pan and Tilt Home Positions can be defined by the user.
A virtual model of the
Camball
can be downloaded from Cast Software. This can be used
directly with the
BlackTrax
There is a little backlash in the pan & tilt axes. This may be noticeable on very tight lens angles
when moving to a position from different directions. The VR versions use the shaft encoders so
this effect is not apparent.
