    Hello everyone!

    I’m having an issue as I am attempting to calibrate the projector. After a complete cycle of taking measurements of the CD I get the following error: “Some tie points have negative projection weights. Please start from scratch.”

    If anyone has any advice for the likely cause of this error I would love to hear it. I suspect it may be because I took careless measurements and I need to be less hasty. I didn’t take any measurements under the sand via calibration so maybe this is a problem as well.

    Any thoughts are appreciated. Thanks!

    I have fixed this problem. I rotated my projector 180 degrees about the axis orthogonal to the sand surface and for some reason I did not get this error and the calibration was an apparent success. (I did have to run the program as as superuser (sudo) in order to write the file after one round of calibration).

    Also see the march 8 2017 post of Oliver. Stability in the recording of the points is required – ideally have two people do it. It took me 5-6 tries over more than a few hours.
