Apologies for the coming abuse...

Hey all,
I added some new splines to an old model to try and make it more realistic with proper muscles. With anatomy books in hand, I laid in some new splines to try and make the things look right.
Let me know what you think about my first iteration on this effort:
-
So what I'm hearing is that I should limit my rotations something less that 30 RPS. I would agree that would most likely fix my slow down issue, but limit the depicted RPM rate to about 1800 RPM. Then the next question becomes how would one simulate RPMs greater than 1800?
Well, I mean, do you want the rotation to appear to be forward or backwards? Nyquist just says that you lose a true appreciation for the underlying signal if you sample at too low a rate (FPS).
If you don't care about the look, just go for whatever rotation speed you want to show up on screen (below the 1800) and then use a phony motion blur or extra set of 'virtual' propeller blades to give the illusion of really fast travel. It was used to great effect in Bob Fleeman's "Skeeters" sketch.
-
I'd probably agree with the Nyquist thing.
But, then again, you'll be Nyquist limited at anything over 30 RPS (1 rev/frame), so why bother? It will give the "authentic" look that you would expect on TV or film.

That's cool from a Sweeper point of view, but a technical nitpick...
Would you really want the track to be that curvy? I would think in the early days of Mars if outposts are spread far around the planet, you would want to be able to travel fast, meaning a straight track.
Also, having it that curvy also seems to defeat the purpose of having risers underneath.
I know - too nitpicky - it is a fun use of the Sweeper. But I know that I would make the tracks as straight as possible since there aren't any obnoxious county folk or anyone to get in my way yet.
Anyways, carry on, nice-looking picture.

Feel free to WINK, link or whatever seven.
I tried the speed Expressions, and managed to crash AM a few times. It really does not like self-referencing.
If I could figure out a way to do numerical integration with Expressions, I see a lot of possibility.
Of course, if I could figure out GetWorldPos and GetWorldDir, that would make a lot of neat stuff possible too....
-
Sorry for the multipost, but did those quick to ensure the file worked.
Small explanation - the Tornado was implemented as described in my Expressions tute. I just did two keyframes on the radius in the movie - more are certainly possible for more interesting behavior.
-
And the movie:

Here's the Tornado project file and a movie (if size limits allow the post):

Hey folks,
I was requested by seven to add something to the discussion.
As I had written in that tornado example, it is possible to use a pose percentage slider as a kind of "dummy variable," simply inputting whatever numbers you wish over time to change the outcome of the Expression.
The drawback to this that I have yet to solve is that A:M currently does not do well with velocities or accelerations. The reason is that you can only deal with properties directly (position, rotation). Normally, in a program, I would write something like:
Pos = Pos + speed*time
in order to update the position based on a speed function that changes over time. This is an illegal Expression as far as I know.
I'm curious to see how the pose enforcement trick works. In my mind, I don't see how it would work with speed any better than the Expression.

Here is a little experiment with brush strokes:
Passing Clouds
Wow - that is absolutely cool!
I really have to give accolades to all of you guys in this section. I'm still struggling with realism, and you guys have blown clear through to the other side!
If I can impersonate MM for a moment, this just strikes me about a comment that I used to make about electronic sensors - all they are good for is corrupting perfectly good information with noise. Same could be said for us.
But, in the same way that having a perfect, isolated tone is not so musical as a Stratavarious (sp?) with many, warm harmonic subtones to match the main one, these "degraded" pictures from a view of photographic reality have a much nicer feel than plain renders.
I'll bet this technique could also be used to get really nice comic-book India-ink paintbrush shadows like old Stan Lee style.

One more random idea with this:
Anyone remember any old/really limited animation pieces where series of watercolors were "animated" by cross-fading from one frame to the next?
You got really limited animation (around 10 fps), but also a really floaty/dreamlike quality to the animation. As an example sequence, I am thinking of an ocean scene with several seagulls - and the seagulls kind of fade from one position to the next. The motion is not quite continuous, but if you sped up the reel just a notch, you would see full motion.

What would happen if you used a light (i.e., a light with an image in it) to project the image of Thom walking on the hair background rather than controlling the color map directly?
It would make the jittering go away - but it would take a bit of experimentation I think to get the look down.
-
And just to help everyone out:
There really is something out there for everything. I've already learned from the Evolution thread that the Quaran considers that a human soul is born 40 days *after* conception, unlike the Christians. Would bring an interesting dimension to a current major debate....
Although rather than blowing your mind up with that kind of play, I'd also recommend The Future Does Not Compute... only the first couple of chapters though. You get his point on analytical thought by then and then it's just tedious.
-
I know that when I "uh oh" in my chair (my best explainer for when I'm falling back), I kind of flap my arms either looking for something to hold onto or trying and shift my balance forward again.
I don't know if the arm thing would be the way to go, but I just seem to think of some kind of jerky movement at the moment of realization and then consignment (as he just tries to hold on).
-
I love the kind of snowboarder's "whoa, dude, that was awesome" take when the kid realizes he's okay at the end.
To go with John's other hand note, I would ask about one small detail - would it help add a little tension to have the fingers claw into the planet (like guardrail before a fall)? Or maybe arch the arms like he's either spazing or trying to pull back up?
It's such a nitpick with the rest of the piece though. I'm sure that the kid has the exact same expression I have when I rock too far back in my chair and panic.

Junk DNA... that was the first thing. I kept laughing thinking of a bag of junk DNA with a big caution label...
Sounds like 'Abby Normal' type stuff to me. Maybe a follow-on for the sci-fi/fantasy contest?
-
Nice details in there as well! I recognize all the dispensers and things from high-school biology class!
You're missing the Jacob's ladder, though.... I mean, how else are kids supposed to practice their mad scientist cackle?
-
I actually like the persons suggestion about the finger wiping Earth into existance. Another might be to show the creation of Earth(or the 6 days worth of creation), zoom out and fade in the words Creation Museum.
You mean like the dividing of firmament from the earth? Could be a pretty good vision.
-
D Josepth - I have always been partial to making swooshes and other such features 'kinetic' - meaning that it fades from the beginning to the end. But it does sometimes look amateurish when I do it, so use this advice with caution.
BTW - Companion thread is open in Rants. And John, yes, that article on the "Tsinami" is indeed quite sick.
-
Well, after reading what's available on the nets and your description, I can say that the place certainly looks interesting. I may even visit sometime to heighten my own scientific training sometime if it proves to be of sufficient quality. Sounds like a neat place for the U of Kentucky (if they have a good biology program) to send some students to sharpen their mettles as well.
Maybe I'll have to see about the commentary on ICR's similar project in California and see if I can dig up any good stuff from talk origins for a Rant.
To be honest with you, it's really, really hard to not be queasy when I see projects like this.
-
It would be cool to see this in another perspective. The balrog really doesn't look all that threatening to me at the moment - even in a comical sense.
The models themselves are, yet again, pretty darned cool.
