Re: [osg-users] Flush event stack
Hi, Lalit You can transform point to screen coordinates by multiplying with correct camera view matrix(if your coords in world space) and camera perspective projection matrix. Cant help much with finding nearest points tho. Cheers, Sergey. 02.05.2011, 14:39, Lalit Manchwari manchwari.la...@gmail.com: Thanks for reply, I have some another question. Using osgUtil::PolytopeIntersector we get the x, y, and z coordinates at current mouse position. Can I do opposite of it, means if I have x, y and z coordinate then, can I calculate the screen coordinate. Actually I have to find points around a given coordinate. Or is there another method to find the nearest points around a given point (range is also given) Thank you!

[osg-users] Flush event stack
Hello friends, I am working on 3-D point data and using osgUtil::PolytopeIntersector to get the x, y, and z coordinates on mouse move event and show it on status bar. But my program becomes very slow. I had make a class: class CMousePickHandle : public osgGA::GUIEventHandler and working on osg version 2.8.2 . Is there any method for flush the event stack? Thank you!

Hi, Lalit You can get event queue from osgViewer viewer or view and use takeEvents method, it leave current queue empty.
