Drawing with cellular automata (Read 2515 times)

metaphorical YaBB Newbies Offline Posts: 8	Drawing with cellular automata Jun 18^th, 2005, 2:07pm This is from a shockwave sketch I made about 4 years ago. The idea is to treat each vertex on the line as a cell, and each vertex will move according to the states of the neighboring cells... using dodgy algorithm + rule 30! Quite fun to draw rough outlines and watch how it develops http://www.metaphorical.net/form/winding.html

I think you've developed a really neat drawing tool. The effects are varied and strange, unpredictable and interesting.

The difference between slow and fast movements make a huge difference, I like that feature.

It would be nice to see the line as you draw it, before it begins iterating new lines... also I think it would be nice to draw several separate lines and have them iterate in their own time. At the moment, if you draw a line and then draw another, the previous one stops iterating - making it difficult to draw over and over.

You could also have a setting where you draw all your lines, and then press a button to iterate them - you could watch the drawing grow, after penciling it out.

I think I noticed a bug. When you click and drag, the point where you first clicked is sometimes ignored. I presume you're only tracking mouseDragged(), perhaps you should track the x,y on mousePressed() for the first instance of a new line?

The lines iteratng by their own time is a great idea... I shall overcome my fear (and laziness) over multiple arrays and counters Thanks for the feedbacks and ideas!
