Think 3D !
Sometimes in programming, the current loop statements such as for...next or do...while can't help us and we need more.
This is a simple and funny program that shows you how a function can refer to itself and make a loop.
I use this function to make a tree, because I like trees, but you can use it for making virus growth simulation!, if you like.
This program may help beginners learn more about graphics, mathematical algorithms, fractals, API, recursive functions, sounds and some VB controls.
I'd like to hear from you, so please leave me a note.

This is pretty cool. Dunno what you're on about with your statement about the for..next or do..while can't help us.
There's hardly any code in this and it works well. 5/5 *****

There is a similar fractal tree at CodeId=23556 but yours is a nicer implementation. Other tree/bush shapes, in case your interested, at CodeId=36449. 5/5

Very nice. I get however "strange" results when setting more than 20 steps.

thanks for all of your comments .
for higher steps you must activate "Brocken Branchs", this make your Tree faster and real,
and also I add 2 new controls to program, see it again ! and please vote for me :D

Very nice indeed. An excellent learning tool for beginners.
T Jackson: I think Mohammad is talking about recursive functions, and how they solve the problems that normal, iterative, routines cause. Although it's perfectly possible to code a routine like this iteratively, a recuerive implementation is much easier to code and understand.

Really nice, try adding "* (Rnd * 10 / 8)" to the end of the mySize line in the next branch function. It makes it look even more realistic. I always look forward to code like this, simple straight forward but produces complex, nice effects.

recall own function...interesting. but this might lead to overflow. as long as the input is controlled well this is good as well.

Brian : thanks. Yes, overflows are everywhere, but we must control them.
