Good morning everyone, I hope everyone of you had a nice and enjoyable weekend? Here in Germany it was brilliant weather, in addition, yesterday was mother's day so we had a very enjoyable time with the family - hope the same for you! :)
Anyways - first off, thank you all very much for your answers. Torben, I did read into your code on Friday and, from a first glance at it, it seems like a possible solution for the problem. I think the perfect way to create that matrix would be by using a camera and creating the distortion pixel map by analysing the offset dynamically via the camera image. It's a quite complex way to do it, but the result should be quite good - however, if I can't find a student to write his bachelor thesis on that, I fear there won't be resources available to do it ;) Shayne, thank you very much - the links you offered perfectly describe the issues I'm dealing with. If I understand you right, I am already tweaking the frustum to calibrate the viewing area by using setProjectionMatrixAsFrustum(left, right, bottom, top, near, far); . The problem with this method is that by using each of those parameters I can only move an entire border of the projection area - so the entire left, right, bottom or top border of the frustum. This allows me to adjust the frustum such that it does fit into the projection screen; however, it does not help at all against the distortion in the image. To do so, I had to be able to move the corners of the frustum individually, and that's something I don't quite know how to do it. I'll read into the paper more deeply and will let you know if it could help me any further. Have a great start in the new week! -Alex ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39189#39189 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
