Flash Bokeh

Sometimes your best efforts to convince clients to originality end up in the trash... but on the other hand there is nothing wrong with it – just shake the dust off and share. This time it's the colourful realtime bokeh effect inspired by this tutorial and programmed for tictoc as a proof-of-concept demo.

Flash AS3 Bokeh

Click the image above to preview. Due to expensive alpha and blending processing it may slow down your browser/computer a bit. I've tried two approaches there:

  1. Adding and removing circles to the display list (with cacheAsBitmap turned on).
  2. Drawing circles onto (transparent and non-transparent) bitmap using draw() method.

Both methods eat similar processor time. Haven't tried using any GPU wmodes, not sure if that would help at all here, I'll leave it to you - the code is very simple and there's a lot of room for improvements and optimisations.

Considering the recent HTML5 vs Flash war, the challenge is to code a similar effect using JS + HTML5's canvas and compare the speed – is anyone up for it?

Grab the source (AS3, Flash CS4 was used to tween the circle shapes but you could entirely use drawing API if needed) and enjoy!
