Wireless InertiaCube3 with Vizard

The wireless IC3 is supported from Vizard version 2.51 on/

Here a couple of tricks:

A) IServer: The IServer application (version 1.40) that comes with the IC3 seems to be stable and functional and we recommend to use it. If several InertiaCubes are connected, the IServer application shows separate tabs for each.

B) Device Tool: The Device tool that comes with the IC3 is well documented. It allows configuration of wireless InertiaCube3 sender / receiver combinations.

C) Vizard: different InertiaCubes can be added one by one by using the commands:

tracker = viz.add('intersense.dls')
tracker2 = viz.add('intersense.dls')
etc.

If you want to specify which port is connected with which IC3, use

PORT_INTERSENSE = 13
tracker = viz.add('intersense.dls')

PORT_INTERSENSE = 14
tracker2 = viz.add('intersense.dls')

etc.

D) if the IC3 is not detected in Vizard or the IServer application, try unplugging senders (battery) and receivers (USB port), quit IServer or the Vizard application. Then plug back in and restart IServer or the Vizard application.

E) example for using two IC3-s for manipulating a simple envirnment:

import viz
viz.go()
#Add a ground plane and hedra
viz.add('tut_ground.wrl')
hedra = viz.add('tut_hedra.wrl')

#add Intersense tracker
tracker = viz.add('intersense.dls')
tracker2 = viz.add('intersense.dls')

# The timer function that will grab the
# tracker data and update the orientation
def mytimer(num):

#Get the data from the tracker
data = tracker.get()

#Only rotate the yaw of the body orientation
viz.reset(viz.BODY_ORI)
viz.rotate(viz.BODY_ORI,data[3],0,0)

hedra.rotate(tracker2.get()[3:6])

def mykeyboard(key):

#If the R key is pressed, reset the tracker
if key in ['R','r']:
tracker.reset()

#Create the keyboard and timer callbacks
viz.callback(viz.TIMER_EVENT,mytimer)
viz.callback(viz.KEYBOARD_EVENT,mykeyboard)

#Start the timer
viz.starttimer(0,0.01,-1)
