Full Version: A way to rotate an object where you just input the # of rotations...

Hi,

It's an old long lost AM'er... me again. I once saw how to rotate a wheel in an old SIGGRAPH video where all you did was enter the number of rotations (at least that's how I remember it... how fast... don't know??). Anyone remember something like this? It's very cool and if I find out again I'm going to document it so I don't forget it again!

Cheers,
Rusty

The Mufoof stuff is also on one of the Extra's DVD's. I think in the tutorial section somewhere.

Great stuff by the way. It is a really good "go to" for airplane props/ etc.


ALSO....for wheels on the ground, there is a formula to calculate the rotation to distance ratio. A long time
ago there was a tutorial on this also but I'm not sure where that one is.

stride length = circumference of wheel

Very interesting thread! Not what I'm looking for but wow, I can definitely use this stuff!

Rusty....

You may be thinking of the channel switch.... The rotation channel must be switched to Euler so that when you go beyond 100% it doesn't go back to 01, 02, 03, etc.
Instead, when in the Euler mode the digits keep moving up 100, 101, 102,.........302.......4,500..... etc. This extends the rotation range beyond 1 single loop.

BTW, I'm rotating 'asteroids'... my bad in saying a wheel (I don't need stride length).

Hi Rusty ....
the simplest way is to use an expression.. I tried demonstrate this method in the tutorial below

Did you get it turning right, Rusty?

Totally F'ing AWESOME!! Xtaz, thank you so much for the trouble you went to. If I new more about the random function (I'm sure such a fuction exists) I could get all the asteroids spinning at different speeds... even in a flock I think.

I have to check out all your tuts.

Cheers,
Rusty

Thanks for asking! Funny... I posted exactly what I was doing... with pictures and a video but... not there???? Anyway, no... but the expression suggested should fix it up. I'm about to self publish my book and while it's getting yet another proof I decided to put together a short trailer. That's what this is all about.

BTW, I totally planned to upgrade now that it seems Netrender is back (I'm still on V14 so I can use the unlimited Netrender we had back then with all the damn PCs I bought) but... my daughter's returned to college which means... we are suddenly like so broke until next year. :-(
