CGTalk - Fast-motion Grass

Hi, I'm having this exercise for college, making a teaser for a book. I choosed an old botanic book. Now, I'm making a plant growing, like shooted in fast motion, but has a sketch look, and in fact it's 3D. The plant starts as a bulb under the ground, and I used hair for making the grass. I want to make it blow by the wind, but I can't figure out how to config the parameters right. I gave 0 to gravity, put wind, put noise to the strength (because I can't figure out how to use the trubulence), the frequency was 0.5 or 2 and yet, the hair flows only to one direction - and that's the better case :hmm:

How can I animate the grass right, so it blows very fast, like in fast motion?

Please, someone, I need to finish this project in the following 2 or 3 weeks (and it's not my only project for college), and I need to show something in the following monday, for the lesson. Can anyone help me?

Not sure how to do it with hair but if you collapsed it to geometry (or made a geometry grass stalk and scattered it) then Michael B Comet's old script "Blowgrass" is useful for this kind of thing. It animates an object with a bend modifier randomly swaying in the wind. You'll find it on http://www.comet-cartoons.com/maxscript.php or click here (http://www.comet-cartoons.com/3dfiles/blowGrass.ms)

pudgerboy, thanks, yet:

A friend adviced me to use 2 wind objects, and give them noise in the strength. And here something new i didn't know: pressing Ctrl+M in the strength parameter in the Curve Editor gives me a multiplies, so I can give -1 to one of them, so when one is strong, the other is week and vise versa, and this one, plus tweaking right the grass gave me a fine effect - not exactly what I wished for, yet, it's good enough for me (ofter all, i'm learning visual design and not 3d).

Ah, max finished rendering a preivew, and it looks even better then i expected. I wounder how the render animation will be! wiiee!

I'm proud to announce that I've finished the project. The typographic is my Achilles' heel, and I'm aware of its being lumpy...

So here's the link: Botanic (http://adi-abinun.roxr.com/Botanic.html)

Hope it'll work for you, 'cause it doesn't work for everyone. By the way, QuickTime 7 is required, and be aware, some told me it crashes their IE! so use firefox or atleast, don't keep important open sites while trying this (at home) :p

Really good job! I like that style alot.

The overall movement and shakiness of objects gave just
the right feeling how "fragile" and light they are.

I agree that this doesn't work for everyone. Well, it's not
giant metallic scifi babe. :) For me, it was really nice
to see this stylish animation for a while. Thanks.

So where are you showing/putting this animation?

Lol, when saying "doesn't work for anyone" i actually meant "i have some problems with the server", but you're right too, and I'm aware to it, and in fact, I prefer the "doesn't work for anyone" style than the common style that goes here :p

Anyway, I've showed it to my class last Monday, and they liked it. They had some small comments about the typographic, which in the paragraphs, shouldn't appear in the same time, but should show the important words before, to help the audience understand anything which is written there (or to write it smaller). Well, in a way, I fell like the texts are too big, it started small and fine, and somehow, like zooming, which while working I thought it has sense, it gets bigger, and bigger, but now I just think it's too clumsy.

The teacher tries to show our works somewhere else, but only once. It's not going to perform for a whole week or something, and I wonder if they'll be more people there then just the class. Unfortunately, our college doesn't put much effort to show our works in publid :hmm:

Anyway, I decided to pass it to the finished animation section (http://forums.cgsociety.org/showthread.php?t=317459)
