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.

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.

6. Sharpening the tools • Faster Algorithms • Code Tricks & Best Practices • Better Compiler Optimisations • Bytecode Manipulation • Thin Runtimes

7. Why its important to us • The only way of discovering the limits of the possible is to venture a little way past them into the impossible. - Arthur Clarke.

8. Contestants, start your engines

9. 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

10. The rules… No Cheating!! • Create a massive amount of points in 3D Pixel Cloud. • Draw the pixel cloud on the screen every frame. • Reduce/increase particles until frame rate is close to 20 FPS. • Language specific optimisations allowed.

11. The Creature • Mac Book Pro 15” • 2.66GHz Core 2 Duo • 4GB Ram • GeForce 9400m(256 MB) • Mac OSX (10.6.3)

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

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

14. Java Applet

15. Action Script 2

16. Action Script 3

17. Alchemy v0.5a

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

21. Silverlight 3.0

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

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

25. WebGL – Hardware Acceleration

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

28. Objective C (Cocoa)

29. OpenGL – The God of Particles
