Simulate broken glass
Jan 16th, 2009, 8:17pm  
Hello all

i am trying to generate broken / shattered glass (fractions) on the screen. It should look different every time.

Examples:
http://www.bigtrapeze.com/images/iphone_crack.jpg
http://iphone.macworld.com/images/2007/08/shatterediphone-large.jpg

What's the best approach for it? I already tried some L-System and noise code without good results.

Thanks for your help,

elsys

sounds like you need some subdivision.
i'd recommend starting with a voronoidiagram.
you can get that running quickly by using the mesh-library from http://leebyron.com/else/mesh/
by tweaking the right distribution of nodes you input, you should be able to achieve a look like broken glass.
maybe noise works, maybe you'll need some attractors too...
then you'll have a geometric clean subdivision. you could get at the points and edges you get back from the voronoi and make further tricks to add distortion and features you'd expect from broken glass.

Interesting, Lenny. I wonder why this library isn't in the Libraries page, it seems useful. I will play a bit with it.
