Shape mapping (Read 937 times)

Shape mapping
Oct 1st, 2009, 4:58am  
Hi, I am new to this... sorry if I'm using the wrong terminology...
I'm trying to map artwork on letters (thinks of a letter covered in ivy).
Is there a ready made solution to this?

I am thinking about an algorithm checking whether the center of the ornament falls within the boundaries of the letter, but it gets tricky when you have a compound shape like the letter O for example. Any advice greatly appreciated.

you can use get() http://processing.org/reference/get_.html
to check for the color at a specific point. Lets say youve got an image like this : http://is.gd/3Qouh
you do something like:  if(get(x,y)==0) then draw ivy, or whatever you want. I have used this method in the past to grow some stuff on text :

You might want to draw the letters one by one by adjusting the position of the pattern, but that's a start.
