I have had a 16:9 flat pannel for some time. For the first time in several months, I built fgfs for osg from fresh svn and fresh cvs. What I noticed right away that has changed is that osg fgfs does not handle the --geometry=1680x1050 correctly anymore. The height of the image is too small for the width. The gages are not round. The plib branch still handles this correctly. Are you seeing what I am seeing or have I missed a patch? When I adjusted the width of the window until round objects are round and then measure the aspect ratio of the adjusted window, the aspect ratio is 4/3. Here is what comparing the plib to the osg response to changing the value of /sim/current-view/aspect-ratio-multiplier tells me: In plib, it adjusts the displayed aspect ratio. I can get the same distortion in plib fgfs as in osg fgfs by changing this value to ~1.2 instead of 1. But if I try to "fix" the view in osg fgfs by adjusting this value from 1 to 0.83333333, all it does is scale the distorted image. i.e. it is adjusting the effective fov, not the aspect ratio. - Dave Perry ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
