Crashing when I select Tracker option
 
I have a script that runs fine with HMD, Full screen and stereo selections. But when I also select tracker option. I get the following error.

winviz.exe has encountered a problem and needs to close. We are sorry for the inconvenience.

I have about 10 of the pic files loaded in the environment. so I have 10 sets of follwing:

screen1 = viz.add(viz.TEXQUAD)
screen1.translate(0.8, 1.500, -1)
screen1.setEuler(90, 0.0, 0.0)
screen1.scale(0.8, 0.5, 0.5)
image1 = viz.addTexture( 'pot.jpg' )
screen1.texture(image1)

When I remove all or some of them.. the program works with the Tracker option.

Do you know why? Is there something I can do to fix it? is there another way to post pics in the environment?

Thanks.

Can you post the entire script using the [code][/code] tags? Also, is your script connecting to an InterSense device?

The crash is probably related to the InterSense. The drivers provided by InterSense will crash sometimes when searching for a connected device. The solution is to explicitly define which port the InterSense is connected to. For example, if the device is connected on COM port 1, add the following line of code to your script:
Code:

PORT_INTERSENSE = 1

Thanks! It works great now.
