GLCanvas creation w/ GL3.3 core sample?

Hi, guys -

Are there any official code samples illustrating the creation of a GLCanvas with a desktop GL3.3 core context? I have found some samples of GL3 JOGL code online, but I'm not sure they really indicate best practices. I'd really like to see something that I knew illustrated the proper intended usage.

Thanks as always -

Hi

elect has some samples using OpenGL 3 and 4 but some of them rely on his third party libraries:
https://github.com/elect86/jogl-samples

https://github.com/elect86/modern-jogl-examples

https://github.com/elect86/helloTriangle

Thanks for the links - this should give me what I'm looking for. This is one of the sets of examples I'd seen before posting the question (having investigated your links re: GLM substitutes in Java). Good to know it has the stamp of approval.  (I don't anticipate any trouble porting the new GL app code itself, it was just the JOGL set-up/context creation I was uncertain about.)

Thanks again for your time.

There are some minor issues with this code, it doesn't respect all good practices and I personally reject the use of third party libraries duplicating more or less what could or should be done by JOGL but elect has done an excellent job in porting tons of modern examples to JOGL.

You know, this kind of goes back to my question about the math libraries. Does JOGL itself have matrix/vector math functionality similar to GLM? (That isn't deprecated from the forward-compatible contexts?) I'd just as soon use built-in capability, if possible, but I would like to stick to forward compatible stuff exclusively.

And thanks for the continued help.

You can look at the classes in the package "com.jogamp.opengl.math". The classes of this package are less complete than the third party libraries JGLM and JOML but we'll probably reduce the gap in the future. These libraries are tiny, I really think that JOGL should provide similar features without becoming "bloated".
