Recursive Trees

Friday, July 31st, 2009

I spent the better part of this past week trying my hand at creating a decent-looking recursive tree, in between all the sweating this heat wave is causing.


Maybe it’s the heat but I think I’m ready to throw in the towel. I got the recursion working reasonably well, but the branch curves look terrible, and most of the logical adjustments I wanted to make ended up in division by zero for some reason I couldn’t track down.

Like, a for loop starting from zero and incrementing i on each iteration; I get that for the first iteration i = 0 so you’d think this equation should work, right?

    variation = multiplier / (i + 1);

But no such luck. “Division by zero” error. My actual code is more complicated of course, but that’s the essence of it; the loop is just not behaving as I’d have expected.

So I think for now it’s time to put this sketch to bed and move on to something else. Shame, I had some interesting things I wanted to do with the trees eventually.

Bezier Stalks

Friday, July 24th, 2009

So after yesterday’s Bezier celebration I thought I’d try a more structured approach and see if I couldn’t capture some interesting movement. Reducing the number of objects down to 3600 and plotting them along a grid as a start, I got the end points and curves moving along Perlin-assisted paths in kind of a wind-blown look.

Still all in 3D space of course, so I saved out a quick capture with some viewpoint shifts and generated palettes. (With the latter you can pretty clearly see that not everything that’s generated is usable since I have to cycle through a few different palettes before I get something decent).
