JOGL 3D Rendering broken on macOS >= 10.14

[Spiess]

Feature extractors and exporters using the JOGLOffscreenRenderer crash on macOS >= 10.14 with the error NSWindow drag regions should only be invalidated on the Main Thread! as described in this forum thread.

The issue is fixed in the 2.4.0 version of JOGL, but this version is still in development and not available as release version.

As there appears no clear timeline for the release of this next library version, is there a workaround which could be used in the meantime?

[Spiess]

Maybe jGL could be investigated as an alternative.

[lucaro]

The LGPL license of that library makes it less than ideal.

What about Three.kt?
From what I understand it is built for real time rendering, like Three.js, but it should probably also work for static rendering.

[lucaro]

Interesting. I just checked, it depends on lwjgl for OpenGL which is better maintained than JOGL, offers access to all kinds of things but is heavier. If anything, we could just depend on lwjgl directly.

You are right, using lwjgl makes a lot more sense. It even has macOS aarch64 build artifacts.
