Hello all. I’ve been searching around the web for some existing code on generating a rock like texture, maybe something like [this or [URL=“http://www.photoshop-dragon.com/Tutorials/Textures/Images/photorealistic\_rock/step6.jpg”]this](http://www.texturise.com/wp-content/uploads/2009/02/texturise_rock_texture_0021.jpg) and haven’t had any luck yet.  
I know it has to be possible, as I found something similar with a [marble texture generator](http://www.connectedpixel.com/blog/texture/marble) but I would need something that has more depth…like a shadow/emboss applied to it.  
I’m thinking you would need to use perlinNoise and convolution filter but am not sure how to do it.

Anyway, I figured it couldn’t hurt to ask if anyone knows of a function or something like that while I continue to search the nets. Thanks!
