[Tut] Spinning Object Tutorial

[BlackHawk]

(I didn't know where to put this, so I think Creative Concepts is fine?)

Well, yesterday in the "What's the first word..." thread Mtank asked how I got a fluid motion out of my spinning fan in my sig. And I said I'd make a tut on how to spin things, since that's what the fan does, and what he wanted to know how to do. [link (http://www.warboards.org/showthread.php?t=37&page=82&pp=10)].

So after spending about 2-3 hours in photoshop, I have completed my first tut. After spending those 2-3 hours I realized photoshop needs to have a more text friendly thing, because it took forever to format this text (probably 40 mins was spent formatting it so it's all nice and evenish).

Without further adieu, the tut:

Or.

You could just have the image in a second frame, rotate it by doing Edit > Transform > Rotate in such a way that only one blade has moved over. For instance, when you rotate it, it should look exactly like it was... then in the animation pallete click the arrow and use the tween tool. Tween it 4-5 frames and voila. The fan spins.

What does NOT work, however, is using only 2 frames when trying to make it spin. That makes it look like it's skipping back and forth.

those 2 hours were well spent....soon i will begin a rotating siggy. (i different kind, though)

[Dark_Soul74]

Fluid motion my a.......nevermind.

I might make one. Don't know why.

[Duddits]

Now that you point it out, you're fan does seem to skip backwards slightly during one of it's fames. Not that it's any biggie, as I didn't notice it till I studied it for awhile.

why do you guys even have photoshop? I mean is this all you do with it or do you use it of rr other purposes other than making signatures. I really don't see the point of buying an $800 software just to make signatures. Did you guys get photoshop cheap or something? HOw do you afford to buy a cd for $800.

buy? BAHAHAHAHAHA NEWBIE.

ok. sorry. but really. what hobbyist would actually buy pshop? NONE.

I got it from my father, who works at HP.

[Duddits]

I will not spam P2P charing programs around here, but let's say that most of us didn't exactly "buy" Photoshop.

[Dark_Soul74]

Your dad works at HP ZDS? As in, the computer company? As in, the one that makes computers and such? As in, could get me a deal on a computer that could beat the crap out of a higher priced Dell?

If you rotate it all in IR then no, because what you do on the first frame, it does it to all frames.

Yes, that's because I rotated each time by a certain number (I forgot which), but that number didn't divide evenly into 180 degrees, therefore the last rotate isn't long enough, so it looks a bit skippy, but unless you're really looking for it, it doesn't really show up.

None of us bought it, we're just kids trying it out (*cough* Kazaa *cough*). Though if I ever did graphic design as a profession in the future, I would buy a full version, but for now free free free! :)

I got it from my cousin, 'cause my dad doesn't want me to download illegal stuff (against IBM policy, and they pay for our internet). So my cousin had downloaded it for himself, so he just burnt it for me :D.

[Battlecruiser]

OHHHHHHHHHHHHHH man I never knew that. Thanks for answering, I was thinking all of you guys bought it. So are there any errors if you get it from k@zaa? or does it work perfectly?

[Duddits]

I'm assuming it works perfectly. The version I have isn't corrupted and works fine. I don't know if there is a difference between legit PS and this one. Not that it matters, anywau, as I'll go one using it.

Nice tutorial.
Allow me to add some comments. You shouldn't always think in 180 degrees, but rather 360 degrees. For the image you rotated in the example, it just happens to be bilaterally (fold-it-over) symmetrical. But many images will not be perfect like this.

Another thing, a foolproof way to ensure that at no time in your animation will the image appear to rotate in the wrong direction, or jerk around, is to do this (Kind of confusing, I can't explain it very well, but bear with): Take for example to example BlackHawk provided. The "wheel" has 10 "thingies" (I dunno what else to call them). Take 360 degrees and divide it by the number of "thingies". Then take a fraction of this number, it can be 1/2, 1/3, 1/5, depends on how smooth you want the rotation, and this is how many degrees you rotate the image each time when you are creating the new layers.

To use BlackHawk's example, his image has 10 thingies. 360/10 = 36. So you could choose 18, 12, 9, 6, or a few others as the amount of degrees you rotate the image around. Doing this ensures that your animation will look smooth, and you will not experience what is called "strobe effect."

well I got it and it works. Now all I got to do is learn it. Thanks guys.

Wish I could DL it but, I have Paint Shop Pro 7, because my mom's old job gave it to her.

Shit I said 180? I meant 360, lol how stupid. Meh I'll change it some time when I'm unlazy, and yea that's what I was going at, and that's why my sig is a bit jerky at the end (I spun it by a certain number that doesn't divide evenly into 360, so the last one doesn't rotate as much a degree as the others, therefore it looks jerky).
