[osg-users] Get the camera axis (X,Y,Z)
Hi, I'm trying to get my camera axis because I want to rotate an node according to these axis. I have a camera controlled by a joystick and a node, sometime I move the camera around and sometimes I need the node to rotate relatively to my camera also using the joystick, so I'll be able to rotate the node left/right up/down relatively to my camera current position I hope I explained my self fair enough.

[osg-users] I need your opinion in 3d lighting techniques
Hi, We (www.jct.ac.il) are making a 3d viewer for non-continuous functions in n-dimentions (well there 3d projection to be precise). What will be the best techniques to make the model look good. by good I mean colors,texture,shadows techniques,lighting techniques.. I know it;s a general question it's just we never dealt with such issues, until now it was all hi-math.

Re: [osg-users] I need your opinion in 3d lighting techniques
Well, basically we have an Mathlab solution that do all the math and generate many .STL files per function. I load the files with our custom .stl file reader into a scene, base on some math calculations I switch the onscreen object/node/.stl data with another object/node/.stl data. For now I'm using basic color per vertex to paint my function and the color change on the up/down axis. I find the result to be lame and I'd like to see the scene much more. I dont know the word in english, to be more live or something like that. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=9324#9324 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] How to count polygons in view
Hello again, I tried your suggestions and got no where, we are to present our work at CERME6 (http://cerme6.univ-lyon1.fr/) due to Jan.,28th - Feb.,1 , 2009, we are working pretty intensive in developing our uniques math alograthim, again we are using OSG as our graphic engine. I really need more specific info about finding the number of polygon on screen on each frame. We are using this number with other data as an approximation of the distance of the camera (using the current heading, not the global distance. I mean my camera can point somewhere with the distance of 300, but the camera is really 2 meters from the surface behind )from the surface, well we have some really cool functions with crazy presentation. sorry to bother you, If you know of any OSG in Israel that will be coll. thank you ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] How to count polygons in view
Hello all,I'm a new around here. So far I've managed to get around but I'm stuck on a simple task. How many polygon do I have on screen right now. I saw the post http://groups.google.com/group/osg-users/browse_thread/thread/6e2894a28daa2f68/435314f8a1ffafc3?hl=enlnk=gstq=number+polygon#435314f8a1ffafc3 But I just can't make it work. I did some thing like that: osg::viewer viewer; . . . . . RenderStage *rs = new RenderStage; rs-setCamera(viewer.getCamera()); but nothing updates any 1??? thank YoU. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
