i get a example to roam about in the scene. but it only support move left/right/forward/backward by keyboard and rotate by mouse.
my client is familiar with 2D gis software,so he want to zoom in/out by mouse like what he does in a 2D scene. he wants to drag a rectangle box in the screen and then the software zoom In the view to that area. and for zoom out,he also wants to drag a rectangle box, and then the view will be zoom out as the ratio of the size of rectangle box divided the size of the view(window). i am a beginner in 3D and OSG so that i am not sure whether it is possible . if possible,how can i do it? hope i have explain what i want. AHa appreciate for any comments! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8211#8211 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
