Re: DemoFX - JavaFX examples / benchmarking framework
It gave me a big headache, but it's so cool looking at it that I could not stop! :) Thanks for bringing back memories ;) Cheers, Mario 2015-03-09 9:36 GMT+01:00 Benjamin Gudehus : > Hi Chris, > > that's amazing.

Re: DemoFX - JavaFX examples / benchmarking framework
Hi Benjamin, Thanks :) I'll definitely be looking at scene graph when I do some 3D effects.

Re: DemoFX - JavaFX examples / benchmarking framework
Hi Chris, that's amazing. Would it be possible in the future to allow both Canvas and Shapes (in a Scene graph)? --Benjamin On Mon, Mar 9, 2015 at 9:11 AM, Chris Newland wrote: > Hi all, > > I've put together a little framework called DemoFX and a few "demoscene" > graphical effects for measuring JavaFX performance: > > https://github.com/chriswhocodes/DemoFX > > Here's a YouTube video of some of the effects I've developed: > > https://www.youtube.com/watch?v=N1rihYA8c2M (watch in HD if you can) > > There's an abstract base class that takes care of the setup and measures > frame rate and time spent in the render() method so developing new effects > is quite easy.

DemoFX - JavaFX examples / benchmarking framework
Hi all, I've put together a little framework called DemoFX and a few "demoscene" graphical effects for measuring JavaFX performance: https://github.com/chriswhocodes/DemoFX Here's a YouTube video of some of the effects I've developed: https://www.youtube.com/watch?v=N1rihYA8c2M (watch in HD if you can) There's an abstract base class that takes care of the setup and measures frame rate and time spent in the render() method so developing new effects is quite easy. I plan to add some text-based effects and also some 3D stuff. It's all Canvas based and the effects are rendered with calls to GraphicsContext. It seems to run at 60fps on modern hardware with the ES2Pipeline (once it's run enough loops for the JIT compilers to do their thing). I think I've already found one JavaFX performance problem: GraphicsContext's strokePolygon(pointsX, pointsY, count) has about half the performance of the equivalent set of strokeLine(x1, y1, x2, y2) commands. Example (after building DemoFX with ant) ./run.sh -m line vs ./run.sh -m poly Will do a full write-up later. Cheers, Chris @chriswhocodes
