Hey guys,
I followed the discussion with interest. I just checked the lwjdlfx-approach. It looked promising in the first place but it has still major performance issues. It is based on the snapshot functionality in the Node base class. This is actually a similar approach we've seen in the JFXPanel which indeed has horrible performance. From my point of view it is not the way to go. What I really like to see is a way to get a textureID directly into the JavaFX opengl context wraped with an Image object. I know it's pretty hard to do this cross-platform and cross-implementation (DirectX, OpenGl) but otherwise JFX can't be mixed with Third-Party applications. Okay, using JFX on top of a OpenGL game just as a replacement of the UI-framework like Ogre-UI etc. might still be a good point since there is no high performance need. In our case we need both high performance UI and high performance additional OpenGL drawings. As of today I could only use JavaFX with a SwingPanel that encapsulates a JOGL context... just my 2 cents Matthias Am 07.04.2014 um 18:47 schrieb Stephen F Northover <steve.x.northo...@oracle.com>: > The lwjglfx solution. > > Steve > > On 2014-04-07 12:45 PM, Exo Verse wrote: >> @ Steve >> Which approach are you referring too ?
