Troubleshooting FPE
Accuracy
There are several ways to calculate the positions and rotations of the fixtures in your show.
There are several factors that can also impact the accuracy of this estimation, including:
Fixture profile inaccuracy
Poor FPEpoint selection
FPEpoint measurement error
Slack in automated fixture belts
Asymmetry about the tilt axis
Fixture-to-fixture pan / tilt variations
FPE accuracy is dependent on profile information and user-supplied data. If the data is
inaccurate, the computation will either fail or give poor results. Adequate care should be taken
to ensure that profiles do not have errors and that the positions of FPEpoints are accurately
measured.
Best Practices
There are many ways to select FPEPoint positions. The preferred method is to use at least 4
points close to the bounds of your space, as in the example above. Larger angles between
points reduces the possibility of redundant information being used in the calculation. It may
help to think of the points as outlining the base of a 3Dshape that should cover as much of
your space as possible.
