I solved the problem. If you want to do the same like me or something similar here are two important notes:
If you want to move the zFar and zNear clipping plane by yourself you first have to call camera->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); before camera->setProjectionMatrixAs... The secound hint I can give is that the depth information you get in the range of 0 and 1 are not so simple as they look like. To compute the depth in camera/world coordinate unit you can't just interpolate linear. Here are the formulars to compute from depthbuffer values to z in world/camera coordinates and the other way round:http://www.cs.unc.edu/~geom/HOFF/techrep/openglz.html Regards, jojo ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=11336#11336 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
