This snippet is similar to yesterdays post but the visual result is rather different. This one does a little more Matrix3D stuff resulting in a sphere made up entirely of squares. This is obscured by the size of the squares and the fact that they overlap and cut each other up. BitmapData a BlurFilter and a BlendMode give the entire thing a slight glow...
Have a look at the swf here...

That’s beautiful Zevan! I am amazed by your ability to create totally outstanding and different thing every day, how do you do that? It reminds me BIT-101’s calendar with experiments a few years ago.
Thanks Og2t… to answer your question, whenever I have an idea for something I write it down - the result is that I always have a small list of things to try to create. Also, if I find myself coding something interesting during a day of commercial work, I’ll take a few minutes to turn it into a post.
I could actually probably talk about bit-101 for a super long time - I’ve enjoyed that site for years… has always been really inspiring.
That. Is. Brilliant!!! That had to be the prettiest 3D example I’ve seen so far!
Thanks dVyper
yes, too bad bit101 burned out. and too bad I was not aware of actionsnippet.com all this time too
I’m still a big fan of bit-101 even though it is mainly about iphone dev now… If you just discovered actionsnippet there’s lots of stuff for you to mess with, I think I’m nearing the 300th post
ever thought about uploading some of this to wonderfl.net?
yeah, a few people have suggested it … and may just have to start doing that… I started working on a script that would autopost to wonderful, but never finished it… (not even sure its possible actually - never got far enough along with the script)…
open page, paste code, hit save. why would anyone need a script for that.
heh… you forget one important step - convert to document class
I guess your right though, I should probably start posting there…. It bugs me that they don’t have a list of most recently added things independent of rank…
I went back here to let other readers know that bit101 did not burned out completely. I have unsubscribed from his main now iphone-centered blog, but added http://www.artfromcode.com/?feed=rss2 instead.
