DemoFX

Performance test platform for JavaFX. Effects can be layered and scheduled on a timeline.

Videos of the demo effects:

• Part I : https://www.youtube.com/watch?v=N1rihYA8c2M
• Part II: https://www.youtube.com/watch?v=WZf0j4GUFYM
• Part III: https://www.youtube.com/watch?v=9jztG_l8qrk
• Christmas Demo 2017: https://youtu.be/npxfaHAAjBQ

Used to discover the best techniques for optimising JavaFX performance on the Raspberry Pi and Desktop.

# DemoFX Part III scripted demo:
./run.sh -s true -f true -w 1280 -h 720

# Christmas DemoFX scripted demo:
./run.sh -s xmas -f true -w 1280 -h 720

#More Moiré scripted demo
./run.sh -s moire -f true -w 1280 -h 720

In order to run in another java version, like java 9. JAVA_HOME should be set. In MAC:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
./run.sh

If the frame rate is not vsynced on Ubuntu then run:

export _JAVA_OPTIONS="-Dquantum.multithreaded=false"
