Playing around with HTML 5's Canvas

Just played around with HTML 5's Canvas a bit. Won't work with IE (click one of the buttons to start):



Too bad JavaScript isn't a bit faster :/
Update: Wow, this is quite slow on FireFox. Opera rules. :)

sixteen comments, already:

You should try Chrome, fastest javascript afaik.

I tried it in ff, chrome and opera. ff was the fastest, chrome close second and opera was waaaay slower. Why are opera fans always wrong? O_o

Screw JavaScript, use Java and let GWT do the dirty work for you. You can use GWT canvas then: http://code.google.com/p/gwt-canvas/

Same as Matthias. Opera 10 was three times slower than FF 3.5.4.

My speed tests related with JS/AJAX image rendering give me this sequence:
FFox 3.5, Safary 4, Chrome, Opera 10, Explorer 8. FFox just fly.
It’s strange but IE7 was many time faster toward IE8.
Opera is the most JS/Ajax unfriendly browser for me. Seems Opera team have own point of view about this :)

Firefox 3.5 working wonderfully for me; Chrome a close runner-up. Opera, however, is the slow one. One of the main reasons I don’t use Opera is its javascript engine; my own experiences with Opera have tended to lag and/or result in errors with javascript-intensive websites.

Wow, really cool.
Shame about the obfuscation, is that a new irrfuscator thing you’re playing with, or is a Mandelbrot set renderer top secret proprietary code?

No, it’s because I couldn’t include multiline javascript code into a blog post, the software would include br’s :)

Ah, okay. Looks like really good fun, I might have to try this canvas stuff! :D
