Hi G. Congrats... please keep me informed for your release....<br>What Beamers are you using ??<br><br>Regards<br>Frank<br><br><div class="gmail_quote">2012/2/1 Wayne Ledzian <span dir="ltr"><<a href="mailto:wledzian1@comcast.net">wledzian1@comcast.net</a>></span><br>

To fully correct an image with lenses alone would require specialized (read "$$$$") optics. A simple mirror would, however, get you fairly close, the main benefit being fewer wasted pixels. You'd still need the warping software to get the rest of the way.<br>
<br>
There are focus issues with our setup if you're specifically looking for them, but they're fairly minor. They're primarily in the form of a slight misalignment between the RGB channels towards the edges, and a small amount of focal blur, generally less than 1 pixel worth. It's really not noticeable once everything is aligned and blended. This was a consideration when choosing our projectors; in order to have minimum skew at the joints, we wanted a long-throw projector. In order to have maximum depth of field (distance at which focus is acceptable), we wanted a small lens.<br>
<br>
If we had used short-throw projectors, we'd have had to mount them much closer to the screen, with the result of more severe focal issues and strong skew at the edges.<br>
