Thanks! what do you think about LWJGL?
No, i dont drawing any stroke. The shaders are very simples. Not much of nothing. I discovered that whit less PGRAphics objects performance is a lot better. Exist an alternative way or better way to use multipass shaders wittout PGraphics obj? always read about how processing is not the best way to implement shaders. In that case i`ll investigate about LWJGL. but all my system is in java( is just a particle System, like nature of code style). is possible combine both lenguajes?
