Thank you for the quick reply! You are right. I fixed the input and now it is evident that the difference is in the windowMatrix: Code: WindowMatrix 3.4.0: [0] {960.00000000000000, 0.00000000000000000, 0.00000000000000000, 0.00000000000000000} [1] {0.00000000000000000, 443.00000000000000, 0.00000000000000000, 0.00000000000000000} [2] {0.00000000000000000, 0.00000000000000000, 0.50000000000000000, 0.00000000000000000} [3] {960.00000000000000, 581.00000000000000, 0.50000000000000000, 1.0000000000000000} 3.2.1 [0] {960.00000000000000, 0.00000000000000000, 0.00000000000000000, 0.00000000000000000} [1] {0.00000000000000000, 443.00000000000000, 0.00000000000000000, 0.00000000000000000} [2] {0.00000000000000000, 0.00000000000000000, 0.50000000000000000, 0.00000000000000000} [3] {960.00000000000000, 443.00000000000000, 0.50000000000000000, 1.0000000000000000} Is seems like the difference in value [3][1] is what gives the vertical offset on the screen of 138 pixels (between the cursor and the object I normally display on the cursor position). Do you have any suggestion of how I could solve this? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=66811#66811 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
