3Dperception has a unique approach to the alignment of multi-projector systems that it calls Northstar. The solution embeds LEDs into the screen that are invisible until turned on. Then, a precision 3D scanner and camera capture the pattern very accurately to determine the exact geometry of the screen to create a warp mesh for the 3Dperception-certified projectors. This is all handled by an external processor box called nBox.
At I/ITSEC 2014, the company announced a new product called WarpLite. This takes some of the functionality in the nBox, mainly warp and blend functions and ports the processing to software so it can reside on the customer’s IG. The product was developed in co-operation with RPA Electronics. Warplite allows 3Dperception to enter a lower cost segment of the simulation market but will still integrate with other 3Dperception products. WarpLite is controlled by 3Dperception’s nControl software which allows a multitude of image adjustments.
At I/ITSEC, the company had built a 150 x 50 degree FOV curved screen composed of 20 screen modules with the built-in LEDs. The surface was sanded smooth and painted with white paint (from a local Home Depot store). It was illuminated with 6 Barco F50 projectors each offering 2560 x 1600 resolution.
