Re: [JAVA3D] removing childs

[ZACZEK, MARIUSZ P. (MARIO) (JSC-DM) (NASA)]

I would highly recommend NOT REMOVING the spheres if you can avoid it.  The reason is because of the POOR garbage collection by Java3D....this removal and reinsertion will cost you a lot. And I speak from experience because I wrote a program to display a 3D scatterplot using spheres which I would use picking on to remove and then I drew new ones.   Especially since you are using spheres you have no reason to remove them, because you can just change them. You can change their appearance/color and change the size using scaling so you should have no reason to remove the sphere unless you are changing from solid to wireframe or something like that.   SO, instead of removing, I would suggest simply MOVING the sphere to some other place away from the main view....for example, I had a sphere at the center of the screen that was fixed so I just moved all my other spheres inside of it and they were hidden. But trust me, removing and reinserting will really hurt you when you do a lot.      Mario Mariusz Zaczek NASA - Johnson Space Center Automated Vehicles and Orbit Analysis / DM35 Flight Design and Dynamics Division Mission Operations Directorate Bldg: 30A     Room: 3040A Disclaimer: "The opinions, observations and comments expressed in my email              are strictly my own and do not necessarily reflect those of NASA."
