i really appreciate you making this change, but i'm pretty sure that it's the same multiplier (exactly 2) for both wx and wy.

if i understand correctly, the multiplier would only be different if the image was stretched from 1280x1024 down to 640x480, creating a non 1:1 pixel aspect ratio. but what's actually happening is that the sensor is being cropped. you can see this in the fact that squares are still square on the IR+depth images.

i could go through the process of capturing a point cloud with libfreenect and openni and do a comparison so you can see that libfreenect's is vertically stretched. let me know if that would help!
