Since the control room was close to the stage, the Designer version was used to provide wireless control of the 4x4pros. “I could take the laptop which had Designer on it and calibrate the projectors on the stage, which was so efficient,” says Wang Tao, the operator from Redline.
He notes that QuickCal’s “line up points function played a significant role in speeding up calibration. It was a big challenge for us to create such massive mapping on the floor, whose size was up to 8,000 square meters. In addition, a combination of bad weather and having projectors on trusses which swing around in the stadium, a small shift that far away means the image on the stage get misaligned a lot, so we needed to calibrate the projectors once a day. The line up points function was so powerful that when I created 90 marks on both the stage floor. In Designer it only took three hours to get all 98 projectors done. If we had been using other servers, it would have taken at least three days to finish the calibration.”
