Watching Intersense Targets

Sometimes, you will want to see how the Intersense is tracking while Previzion is still running. To see if the Intersense is still tracking, you can actually bring up ISDemo32 while Previzion is on and connected to the Intersense. Since sfServer is already running, ISDemo will connect to sfServer. You can then open Tools->Optical Data Display and display the current tracking state while running Previzion.

Warning — the real time display of the tracking targets in ISDemo32 is intensive on the system, and will cause Previzion to drop frames, so we don’t usually recommend it. It’s useful in the verification and testing stage, however.

To lower the impact on the system, you can shrink the window until it is down to about 2″ x 2″; this lets the system operate more normally. When doing real shots, however, the tracking display should be turned off.

You may also notice a weird rendering artifact (a small dark square) in the Previzion video display after running ISDemo32; that’s due to how ISDemo32 renders into the framebuffers. It doesn’t affect the output signal, but if you don’t want it to be there just move over the Previzion screen so that the ISDemo 32 screen does not overlap it.
