Re: [osg-users] [osgPlugins] FBX texture export problem.

Re: [osg-users] problem in changing view from perspective to orthographic

Hi Nitin, There isn't really any proper way to convert between orthographic and perspective projections, the two are essentially incompatible projections. You can try to make best mappings based the eye point, center of rotation and your field of view in perspective, which makes the scene look
