Hi, In the Docs directory, the write up on multi-screens regards seperate windows states:
"The displays are arranged in a shallow arc with the left and right displays at a 45.3 degree angle to the center display because, at the assumed screen dimensions, the horizontal field of view of one display is 45.3 degrees." OK, makes sense, but what are the assumed screen dimensions, where are they specified, and how was the value of 45.3 degrees for the HOV calculated?? would like to create a frustrum that subtends an arc of 62 degrees ( + or - a few tenths )in the HOV, given a screen size of 1024x768 or 1280x1024 how would one come up with frustrum numbers for the OTW. working on the intial piece of image distortion code that Tim wrote. Have a decent system for building a cylindrical display ( see http://local.wasp.uwa.edu.au/~pbourke/miscellaneous for related topics ) but need to handle the edge blending problem. One issue is how to adjust FOVs for projector misalignments. One can get close with mechanical adjustments and the newer projectors can also make limited adjustments but the fine grain adjustment need to be done in software to create a seamless picture.
