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.
If you are using processing 1.5.1 this might be what you want link, funnily enough I've just updated advice to cope with changes in processing-2.0a7. Advice is tailored for 64 bit linux but I'm sure you can adjust.
wow, cool, it works now! :) http://img685.imageshack.us/img685/5967/processingalpha2opengl.png but I'm not sure if it's the alpha stadium, but I get two areas with the "stop" sign (image, bottom left as usual, but also upper left but without the stop letters on that image). and is it right that there is just the canvas area displayed? because with 1.5.1 the complete screen is black and then there is the canvas on it.
