I would like to do this kind of 3d scatter https://forum.processing.org/topic/3d-scatter-plot but inside a java class, because I do calculations in java that I don't want to do in pure processing. But I don't know how to import the missing OPENGL right. I tested other non opengl things and it worked fine http://youtu.be/MqMHmBnos7k . I added all the jar libraries I found in the processing collection. But there is no opengl and I'm not sure which to take and how to import it rightly.
I found processing via google, because I'm looking for an "easy" way to discplay the current (and some previous) 3d coordinates of clestial objects I want to compute with a java programme. Currently I plot those with OO calc but I want to avoid this extra work and I would like to display it "in realtime" and update the position with each new frame. Could you please help me, how to do that? I use netbeans and I found the eclipse example, but I can't update the frame with the new points. And I currently do the simple things with 2d, but I would like to display it in 3d or at least isometric view.
