7. If you have a PPT wand connected, then you will need to add the following extra
lines:
#Define PPT Wand-can optionally specify number of wands, defaults to 1
DefineDevice pptwand pptwand-trackd
#Specify PPT Wand address(Device ID, PPT hostname/IP address, PPT Wand
light number)
DeviceOption pptwand address 127.0.0.1
8. The above is written assuming TrackD is installed on the PPT machine. If TrackD is
running elsewhere, then 127.0.0.1 should be replaced with the IP address of the PPT
machine.
9. Start up TrackD using the configuration file just written and test the output.
COMPENSATION FOR MAGNETIC DISTORTION
There may be scenarios where the internal wand orientation sensor is affected by
magnetic interference in your environment. If this is the case, then the PPT Optical
Heading plug-in will help to correct this for you using the two lights on the PPT
Wand.
Before proceeding, verify that your Wand has a unique Marker ID value that does not
interfere with any other markers you plan to use. If you’re using your wand in
conjunction with PPT Eyes, then this is not an issue because the Eyes module uses
passive LEDs which do not transmit ID signals.
For this operation, you need to have 3 Post-Process plug-ins set up and ordered
exactly as you see below. If they are not in the correct order, you can drag and re-
arrange them. The instructions below explain how to properly configure each.
