Greeting, wise ones!
I am trying to make a generator for pictures like this one. My idea is to make 2 patterns (vertical lines and horizontal lines). After that, I need to make vertical lines only appear "within" the letter but go a bit beyound if they don't intersect a horizontal line. Same for horizontal line, just for being "outside" the letter.
To perform this I need to know, which pixels are "within" letters of the text() object and which are not. This is the only thing, that I can't get my head around. Any ideas on how to implement this?
(If you have a simpler idea of how to make this generator, I'll happily read about them as well, I'm not too sure that mine is the best)
TL;DR: solution
So, initially, I was doing it in Java Processing and was thinking in terms of points and "if" conditions. I couldn't get any meaningful help and abandoned the problem, doing the thing by hand.
However, later I encountered a problem with detecting if a point is within a polygon in Unity and found a solution that includes the concept of raycasting. It's easily implemented in Unity but will require some extra work in something like Java Processing. In any case, this is an excellent answer to my question. I hope it helps anyone who encounters a similar problem.
