Here are five propellers. Different number of blades, different speeds. They go up till they get to the upper edge of the atmosphere then they come down.
Sorry I didn't post movies, I don't have a YouTube account (I'm one of those.

).

Cool.
Say, I never figured out how to use motion blur in 6.6 / 7.6 Model side.
How do you do that?

Also, you could compress the video file in .zip format if it will fit, and post that.
I'd love to see these videos!

Ok here is my second entry. Softbody physics.

Accu · Post by **Accu** » 13 Oct 2010, 17:06

To use motion blur, when you render to file, you just set it to On and set length and number of frames. For the image with the propellers, tS had to render and blend 100 frames. More frames, better blur and longer time to render.
For frame 10, for example, if you set the number of frames to 5, it probably renders and blends frames 8, 9, 10, 11 and 12 (if you set blur length to x - unknown). It may render 6, 8, 10, 12 and 14 or 4, 7, 10, 13 and 16.

Ok thanks Accu.
Jeff, how do you get soft body physics working? That's cool!

EDIT:

Accu: haha that's hilarious! I like it! Looks like a tennis ball 'shooter',
that tennis players use to practice with.

Accu · Post by **Accu** » 13 Oct 2010, 17:36

I'm making them on a conveyor belt! And with too much motion blur, it seems.
I didn't know tS7 could do soft body physics. I'm way behind.

froo · Post by **froo** » 13 Oct 2010, 18:03

Now that's cool Accu!
I did not know about soft body physics in 7.61 either;
I wonder if Jeff is using cloth physics for it. Nice.

rjeff · Post by **rjeff** » 13 Oct 2010, 20:56

Yes Cloth Physics does do soft body very nicely.

froo · Post by **froo** » 13 Oct 2010, 20:57

Cooooool jeff!

rjeff · Post by **rjeff** » 14 Oct 2010, 00:41

Here is my 3rd entry..softbody number 2.

That's awesome!

Didn't know that.

Not really an entry, as I did this a few months ago.
Cartoon cannon physics, softbody and dynamics in Carrara 8 Pro.

Edit: Adding this video I did in Carrara 8 Beta, Bullet Physics. Did it sometime this year, don't remember.

Very cool James!
I like the cannon especially.

nigec · Post by **nigec** » 15 Oct 2010, 19:47

Awesome enties guys!

should I let it run over the weekend to see if there's anymore? (I need time to make sure I don't miss anyone

)

rjeff · Post by **rjeff** » 15 Oct 2010, 20:20

I say just let it run till the end of October.

nigec · Post by **nigec** » 16 Oct 2010, 17:31

ok, will do

rjeff · Post by **rjeff** » 18 Oct 2010, 19:27

Gears. Simple demonstration. They are not rotating as smoothly as I would like, but I think that is a product of my teeth design.

MikomDude · Post by **MikomDude** » 18 Oct 2010, 19:56

Nice one rjeff!

rjeff · Post by **rjeff** » 18 Oct 2010, 20:23

Why thanks. My next one, it will not be for the challege, I am going to attempt a chain drive.

By the way Mikom..love the BSG reference for your avatar.

MikomDude · Post by **MikomDude** » 19 Oct 2010, 12:01

Hehe, yes. I found this image on the internet once when I Googled "Cylon". I have modified it a bit though.
This is the original:

If it wasn't for this image, I would probably never have seen the Original Series.

rjeff · Post by **rjeff** » 19 Oct 2010, 14:34

Yeah the original series in the 70's was much better than that sham of a program that ran on sci-fi. I watched all 5 years of it, but it was a waste of time.

MikomDude · Post by **MikomDude** » 19 Oct 2010, 14:54

What? You didn't like the remake? Sure, it's different but the story and acting is amazing. It's my all time favorite TV series, even after I saw the original.

I honestly have never heard from anyone that they didn't like it. Even my mum (who I persuaded to watch) liked it and she hates science fiction.

Accu · Post by **Accu** » 19 Oct 2010, 16:43

Good idea with the gears:

I think I was lucky with these, I got them to work with physycs. I tried to make better ones but they wouldn't turn.

rjeff · Post by **rjeff** » 19 Oct 2010, 17:13

I like yours better, they run much smoother than mine. With that said I think most of my issues is with the gear design. Did you do yours on WS or MS?

Accu · Post by **Accu** » 19 Oct 2010, 17:30

rjeff wrote:Did you do yours on WS or MS?

tS6.6...

There's a science for these gears. And I don't know it.

rjeff · Post by **rjeff** » 19 Oct 2010, 17:32

Well please let me in on it. I have a project I am doing to do with them, and I would not mind the advise.

froo · Post by **froo** » 19 Oct 2010, 17:49

yeah ditto that! I wondered how to do that too.

Accu · Post by **Accu** » 19 Oct 2010, 17:50

I guess you read my post wrong. I said I don't know the science. Geometry, math... angle of the teeth and stuff.

Google has a lot of images of gears.
http://www.gearideas.com/images/tech/image11.gif
http://www.maplesoft.com/SizedImages/im ... 64_280.gif

And this - http://assets.cambridge.org/97805218/15 ... 5178ws.pdf.

I recommend trying to model and animate these gears:

nigec · Post by **nigec** » 19 Oct 2010, 17:56

There's a cool program called eMachineShop that does gears, it does cad format exports like DXF, I usually export to Sketchup but in theory the should work in TS
Poly count is a bit scary though

rjeff · Post by **rjeff** » 19 Oct 2010, 18:01

Sorry Accu...I will check out that program. Thanks Nigec.

Accu · Post by **Accu** » 19 Oct 2010, 18:21

Exporting to DXF and importing to tS does something that's not very useful, unless you want to use it for inspiration.

nigec · Post by **nigec** » 19 Oct 2010, 18:49

in sketchup you get a nice lines, I don't think SU8 has a DXF importer anymore..
if you export as igs then open in Carrara, but very limited to how much detail you can have and it needs welding

v3rd3 · Post by **v3rd3** » 20 Oct 2010, 03:54

I started researching gear engineering for the sake of making gears.... here is a link to a pdf that explains an awful lot of the terminology and math.... http://www.bostongear.com/pdf/gearology ... apters.pdf

Another good reference is here ... http://school.mech.uwa.edu.au/~dwright/ ... e.html#top

theuns · Post by **theuns** » 20 Oct 2010, 10:01

wow! this SMC has taken off all of a sudden with a lot of entries!

See, told you it was a good theme

Accu · Post by **Accu** » 20 Oct 2010, 18:29

You said it. Here's another one:

I wanted to add more but I got bored while waiting for the physics calculations.

rjeff · Post by **rjeff** » 20 Oct 2010, 19:59

I like. Curious Accu. Why don't you use TS 7.6?

nigec · Post by **nigec** » 20 Oct 2010, 21:22

maybe the same reason I don't? I don't use or need workspace, 6.6 is faster and just seems to "fit", I don't gain anything by using 7.6 just a lot more clutter

After the shakey start I'm really surprised how well this challenge is going, thanks everyone

Finis · Post by **Finis** » 21 Oct 2010, 00:16

Thanks for this challenge topic Nigec. Thinking of things I could do for it inspired an idea for a short animation. Too much time needed for it to be a SMC or for me to do at all now but I'll do it sometime as a regular project. It will use my Splododyne devices to blow stuff up.

Accu · Post by **Accu** » 21 Oct 2010, 06:45

rjeff wrote:Curious Accu. Why don't you use TS 7.6?

I almost don't use tS at all these days. Switching to 7.6 would take time, I have to learn "new tricks".

I know tS6.6 well enough for what I do. tS7.6 seems too complicated.

If only I had some inspiration...

theuns · Post by **theuns** » 21 Oct 2010, 22:01

there are some tools in 7.6 that is not in 6.6, which is the main reason why I use 7.6 model side only, plus it seems a lot more stable than 6.6 was... (can't recall the list of new things in 7.6 though, will have to go search for that)

nigec · Post by **nigec** » 23 Oct 2010, 11:16

I might not be around for a few weeks, would someone be able to set the poll up if I don't get back by the end of the month?
Thanks

rjeff · Post by **rjeff** » 23 Oct 2010, 14:28

Will you be back? You better!

nigec · Post by **nigec** » 23 Oct 2010, 16:22

Yes I will be back, I'm just covering my a** if I'm gone longer than I want to be, I wont have internet access

froo · Post by **froo** » 24 Oct 2010, 20:17

Ok. Not really an entry; really to bring to your attention, the fact you can create blender fluid sims, import them into trueSpace, and cause them to interact with objects in trueSpace physically.

http://www.youtube.com/watch?v=ajfeynWhDBs"

theuns · Post by **theuns** » 25 Oct 2010, 10:28

froo: WOW! Now I HAVE to start learning Blender ASAP!!!!

nigec: no probs nigec, we've got ur back

rjeff · Post by **rjeff** » 25 Oct 2010, 11:09

I am in process of the same thing Thenus. I downloaded a getting started video, I have not had time to watch it yet though.

froo · Post by **froo** » 25 Oct 2010, 15:55

Hey theuns; the freely downloadable fluid sim importer package contains a highly detailed manual for creating fluid sims in blender. Screenshots for every step in the process are included. Also included is a sample dataset for use in trueSpace.

Link:

http://www.truespaceplugins.com/froo/"

Looking forward to more physics sim videos everyone!

theuns · Post by **theuns** » 25 Oct 2010, 18:28

Froo: XLINT! tnx Froo, checking it out...

rjeff: yeah, have about half a dozen programs I've downloaded with manual and tutorials that I haven't gotten to yet

rjeff · Post by **rjeff** » 03 Nov 2010, 18:38

Sooo...we gonna open this up for voting?

theuns · Post by **theuns** » 04 Nov 2010, 12:24

yes please, would love to take part in the next one

rjeff · Post by **rjeff** » 04 Nov 2010, 14:02

Who gonna get the poll going? Nigec I guess is still incognito!

theuns · Post by **theuns** » 09 Nov 2010, 08:41

does anybody have time to go through the thread and collect links for the poll?

i'm sure nigec won't mind if we start the poll in his absence...

MikomDude · Post by **MikomDude** » 09 Nov 2010, 16:39

Have you got a theme yet for the next challange?

theuns · Post by **theuns** » 09 Nov 2010, 16:46

the person who wins choses the theme and to have a winner we need to have a poll first for people to vote...

Prodigy? Will you do the poll for us please?

rjeff · Post by **rjeff** » 09 Nov 2010, 16:53

Hang on I got to edit the poll..did not add enough options!

rjeff · Post by **rjeff** » 09 Nov 2010, 18:13

Ok poll is open now.
