Hi Wangjian; If you have looked at the osgParticle nodekit, you should know about emitter. I think you want to create a bubble effect on the top of your bottle, so you know related coordinates, at this point you can change the emitter position as you expected. That's all.
Ps : I recommend you to use Delta3D Particle Editor which can create particle effects and save in osg format as a simple bubble effect file and then you can read this file in your application and add as a child to any MatrixTrasform and as a result you can control your effect easily. Hope this helps. 2009/5/1 Wangjian <[email protected]> > Hi, > I want to realize the bubble effect at one position.For example,if I know > the coordinate of the top of the bottle,I want to create some bubble at the > top of the bubble.Can you tell me? > ... > > Thank you. > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=11181#11181 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > -- Ümit Uzun
