Hey all,
it's great to have a new thread like this. Robert exactly pointed out what we actually need. I have seen an approach to integrate JFX in JOGL and vice versa. This approach is always been a copying of the pixel buffers between those two frameworks. From my perspective this is not a real good approach because of obvious performance issues. Yesterday, I had a better idea. my idea: I know it is very hard to have JFX exposing a real GLCanvas/Context. I used JOGL for quite some time and I know the JFX rendering pipeline a bit. Please correct me if I am wrong. The most applications need some point to draw. The best pointer would be an exposed FBO from Prism that can be used by Jogl/LWJGL. Additionally we would need a possibility to share the JFX OGL-Context with another one, so we could reuse this FBO in a second window. Okay, this wouldn't needed if I could share textures over scenes. I know there is one major limitation. In windows Prism is using DirectX by default, so there won't be a possible interaction with Jogl. I am sure some DirectX guys really like to have there hands on the surface-layer as well ;) Well, to used the Jogl way above we would also need a stable OGL implementation of Prism for Windows. Last time I tried it it was not even comparable. I am not sure why, but OGL on Mac and Linux works pretty good.
