JEP-412 & OpenGL

[Martin Pernollet]

Hi,

I actively maintain Jzy3D [1], a framework for drawing 3D charts in Java. It uses JOGL which access native OpenGL with the help of GlueGen, a tool to generate JNI bindings. Jzy3D has an additional OpenGL pure Java CPU renderer [2] to circumvent compatibility limitations of JOGL, mainly for MacOS.

Will JEP-412 close the doors to bindings relying on JNI? In other word will JOGL be able to continue working with GlueGen and JNI?

Are there known plans in OpenJDK for enabling OpenGL (+Metal?) consistently across OS and hardwares via a unified API? II have seen an OpenGL example based on JEP-412 here [3]. I would be interested to assist on that topic and may help making Jzy3D compatible to such API. Jzy3D indeed offers a IPainter interface [4] that allows pluging multiple implementations of OpenGL for Java, hence helping to compare JOGL, EmulGL or any other OpenGL java API.

Thanks in advance,

Martin
