Different random seed for polycon "randomness"?

Postby RobA » Fri Jul 30, 2010 1:09 am

I was trying to use polygons with some randomness to represent trees on a map. They look great, but I discovered that every object seems to use the same seed (i.e. if you have two 4 sided polygons, both with a random of 0.4 they are identical).

Is there anyway to have each object use its own seed?

Unless there a way to write a script or something, I guess you'd just have to change to randomness value for each object. However, I was just trying it out (what the heck, might learn something :mrgreen: ), and I don't see each object looking identical. They ARE generally similar, but not identical at all. I tried it with both the polygon and star modes.

Oh wait, I see. If I create one star/polygon and duplicate it many times, then apply the randomness and rounding to them all at once, yes, they are all absolutely identical. Interesting -- at first, I was just drawing them one at a time, and tried to use the same mouse stroke. But no matter how hard I tried, each always looked different! But I can see that duplicating (or especially cloning) is the culprit.

Would you be able to create them one at a time, or are there just too many? Maybe you could create a small group of them (not Group necessarily), say 5 or 10, whatever is appropriate, doing them by hand so that they are really different. Then duplicate this group, maybe rotate, skew or whatever, as you place them where you want? Oh, or especially if you overlapped the little groups, that should make them look appropriately random. And also, the higher random and rounding values, the more...scribbley they look (so that even if they are identical, overlapping them would disguise it.

That's a great way to depict foliage, btw. I really like it....might have to use it sometime!

OH! Last thought -- maybe there's an LPE you could use???
