Hello, I am seriously confused about the role of the /etc/primesense/GlobalDefaults.ini file in the ros openni_camera driver. In this thread [1], I was told by Suat that the driver does not in fact use that file. However, I get different behavior from the openni driver when I change parameters in the file, leading me to empirically believe that the driver does in fact use it, or at least parts of it. The real confusion sets in when I attempt to change parameters that the Kinect device is supposed to support. For example, changing the WhiteBalance and Gain currently has no effect. I find this really weird, since I do remember being able at one point to turn off auto white balance by modifying the file. I also recently obtained a Axus Xtion Live Pro device. I was under the impression the device should provide hardware sync and registration capabilities - I have not been able to get either so far. I was told in the openni googlegroups [2] that both should be available using the openni API. Is this being handled properly by the ros driver? I might be compounding different problems here, but any help would be appreciated in resolving these conflicting opinions and results that I am getting.
