Release candidate 3 is out!
It’s now possible to output the raw image from the infrared camera instead of the RGB image. This is the raw data the Kinect uses to estimate depth. This means that by blocking the infrared projector (on the left side of the device) it’s now possible to use the Kinect as an infrared camera. Note, however, that the infrared camera was calibrated to work with the infrared projector and you may find ambient infrared light to be either too dim or too bright to be useable.
Even with RC2, some users reported stalling issues. It appears that stalling occurs under heavy CPU load – although I haven’t verified that this is true in all cases.
