Hi all, I agree that we need WebGL support in JavaFX. Recently, I made some experiments with integrating the Qt based WebView/WebEngine into JavaFX via synchronized shared memory buffers (see https://www.youtube.com/watch?v=FlIrY1SlNM4 and https://www.youtube.com/watch?v=CQXG77O2MqQ).
what can i do as a lowly developer to help? The implementation is highly experimental and there is a lot of work to do. Any help is highly appreciated! The advantage compared to the JavaFX WebKit project is that it is not necessary to fork WebKit. The downside is that the integration is not as good. Updating to a new versionof Qt WebView/WebEngine, however, is relatively easy since I'm using a QPainter that draws to a shared memory buffer. JavaFX gets access to the buffer via JNI. What concerns me is the limited API to directly draw buffers without performing too much copying. Therefore, *we need a public equivalent of NGExternalNode* (used by SwingNode, integrates Swing into JavaFX). Kevin, do you think this is realistic for JavaFX 9? Anyway, here is a link to the github repo: https://github.com/miho/VFXWebKit Regards, Michael 2015-06-30 14:09 GMT+02:00 Scott Palmer <swpal...@gmail.com>: > > > On Jun 30, 2015, at 7:21 AM, Mike Hearn <m...@plan99.net> wrote: > > > > ... > > With respect to things like "support WebRTC" or "support WebGL" - > > seriously?
