WebDU 2010 talk. Comparison of various web technologies at their bitmap manipulation speeds. Flash, HTML5 javascript canvas, silverlight, java applets, webgl e.t.c Interesting experiment and interesting results none the less.

1. Need For Speed Every car has a lot of speed in it. The trick is getting the speed out of it. – A J Foyt.

2. RocketBoots

3. Speed Its Addictive DISCLAIMER:We acknowledge that wikipedia makes it sound so cool but don’t try drugs.

4. Speed is awesome Apps feel lightweight. Brings the web to awhole new experience. Faster Pixel Math e.g. Computer Vision.

5. And it can be deadly too Premature optimization is the root of all evil - Donald Knuth. Design first, optimize later.

7. Code Tricks & Best Practices

8. Better Compiler Optimisations

9. Bytecode Manipulation

11. Contestants, start your engines

12. Who can push most pixels ? JavaScript (HTML5) Java (Applet) ActionScript 2.0 ActionScript 3.0 Silverlight 3.0 Alchemy v0.5a / + Pixel Bender Haxe 2.05 with memory API Objective-C / + GCD WebGL OpenGL Pixel

14. Draw the pixel cloud on the screen every frame.

15. Reduce/increase particles until frame rate is close to 20 FPS.

17. The Algorithm initBitmap(); createParticles(); //every framerenderParticles(); Adjust particles until frameRate ~= 20FPS.

18. Performance Comparisons Show each demo. (The fun stuff) Briefly explain code. Measure number of particles when they become stable. Plot in Excel Chart.

19. Java Applet

20. Action Script 2

21. Action Script 3

22. Alchemy v0.5a

23. Alchemy v0.5a with Pixel Bender

24. HAXE 2.05 with memory API

25. HTML 5.0 + JavaScript Safari Crashed Internet Explorer 8 Doesn’t support it yet

26. Silverlight 3.0

28. To Infinity and Beyond Nightly Builds of May 6 2010 Chromium – Chrome Minefield - Firefox Webkit - Safari

29. Redemption (Nightly Builds) Internet Explorer 9 preview went blank

30. WebGL – Hardware Acceleration

32. The Natives Thought we’d try to make native apps to see the difference. Objective C (Cocoa) Open GL + GLUT

33. Objective C (Cocoa)

34. OpenGL – The God of Particles
