SMC #56_Get Physical!
This Challenge is to create an object or objects that can be used in conjunction with your fav software's physics system.
The options are endless, from a table cloth, running water to bullets thru glass its your choice

1) Use any 3D software you choose.
2) Create the model(s) within a 3 hour time limit.
3) The scene can be an animation or static image
4) You may enter as many times as you wish.
5) Your entry will also include a wireframe screen grab before SDS (subdivision) has been applied. This is included to help others learn modeling techniques.
6) Include time spent, software/version and render engine used with your submission.
7) Post one render per entry at 800 x 600 pixels.
8) Render, Lighting, and Texturing are not included within the 3 hour time limit.

deadline is the 27/9/10

Oh man this one seems so classic and cool, I need to get 7.6 fixed

nigec · Post by **nigec** » 27 Sep 2010, 07:11

no takers?
maybe we should scrap this one and have a MOD set a new one? My ideas usually suck ;p

theuns · Post by **theuns** » 27 Sep 2010, 09:30

not a bad idea, nige... i just don't have time at the moment (don't think i'll have time for mmc either

)

nigec · Post by **nigec** » 27 Sep 2010, 10:04

TBH I've had a really bad 6 months and most of the stuff I've done was more the "need" to do something constructive, the smc was just perfect for that.
I've been thinking about quitting U3DA, I rarely have anything constructive to say, and none of us seem to get much C&C on the images we post, Saul's comments on one of my images has about hammered the last nail home for me.

Steinie · Post by **Steinie** » 27 Sep 2010, 11:30

Nigec,
Don't let Saul's comments effect your participation here! Sometimes we
all get comments we don't expect. I am planning on joining the MMC soon and Prodigy
already said he would like to enter the SMC too. We are all going through ups and downs for
motivation so you are not alone. I've always enjoyed your postings Nigec and you would be missed
if you left us. I hope you decide to stick around and offer your support when possible.
(Remember some of the great Artist of the world died hungry and poor)

I think the problem with your topic for the SMC is that it would be better for a MMC instead.

jamesmc · Post by **jamesmc** » 27 Sep 2010, 13:18

I had an entry, but can't find where I put it. As soon as I can find where I put my memory pills, I'll load it up.

theuns · Post by **theuns** » 27 Sep 2010, 13:58

I agree with Steinie, nige... don't let things get you down and quite your love for 3d... even if nobody comments, doesn't mean it isn't good.

It might be that people don't understand or never used the physics options in their software before and find it too daunting, but that is the point of SMC, to challenge you and try new things... so it is a good theme regardless of the lack of participation.

I will make an effort to enter this SMC from my side, always wanted to try out feathers and leaves floating down from a tree...

Reminds me of this old cartoon I have pinned to my office wall

...

rjeff · Post by **rjeff** » 27 Sep 2010, 15:33

Nigec...I demand you not leave. I like the rest of the guys like having you around. As it stands it seems like there is only 10 of us that acutally post on here. You leave then we are down more people. I whish I had more time to do more of the challenges. I am so busy right now that, I don't have time to do as much art as I like. So... you are not allowed to leave. Resistence is futile. Besides you would miss us if you left. Where else can you get images from James and Steinie. Their images are one of a kind! There are alof of people we have lost since Caligari sold it's soul. Nez, Mrd3d just to name a few. I miss all those guys, in a artsy kinda way!

Finis · Post by **Finis** » 27 Sep 2010, 16:54

When things are bad is the worst time to neglect the things that are good. You have friends here. You enjoy 3D and this forum. You shouldn't leave.

Don't count trolls ramblings more than your friends' respect.

People are just busy now. Your SMC theme is great. Maybe emphasize more that it should be usable for physics (almost anything is) but doesn't have to be animated or have physics applied. How about extending it another month?

nigec · Post by **nigec** » 27 Sep 2010, 17:49

Thank you for the kind words guys, yes Nez and Mr3D are sadly missed and a lot of others.
A few years ago I would of bit at the comments, had a rant, and probably looked an arse, but, honestly there's a lot worse stuff to deal with in life.

Yeah we could let the contest go on longer, I wasn't complaining about no one entering, I didn't get chance either

froo · Post by **froo** » 27 Sep 2010, 17:52

I agree that it would be best to make it into a MMC; because when you run phys sims,
you want to make changes, rerun it, etc.

Steinie · Post by **Steinie** » 27 Sep 2010, 19:16

Let me get a couple facts straight here. First Saul is not a troll but a gifted artist from many years ago at the Caligari forums. He does come across as a troll or a rear end of a horse sometimes. I won't excuse him for that. My belief is that he tires of the Poser babe shots as much as I do and instead uses 3D applications to create original Art.
However I did like the 007 look of the lady in glass.
I too have 3 daughters...good luck! Wait until the boyfriends come calling!...

rjeff · Post by **rjeff** » 27 Sep 2010, 20:45

Steinie I got guns for those guys!

nigec · Post by **nigec** » 27 Sep 2010, 21:07

I too have 3 daughters...good luck! Wait until the boyfriends come calling!...

The boyfriend from hell of the eldest is why we've had a bad 6 months, VERY messy split, he's currently sat in prison cell awaiting sentencing for arson with intent, breaching restraining orders and generally been a dick.
I only did 4 V4 models in Thea, two I made look old, the one in a globe and a dressed one, Daz stuff is really handy for high poly tests but a low poly model can just as useful to try and break a renderer.

LeonRegis · Post by **LeonRegis** » 28 Sep 2010, 00:16

OK, there wasn't any entries... I got my tS fixed today, so if you extend I MIGHT be able to do something...

rjeff · Post by **rjeff** » 28 Sep 2010, 02:05

Why don't we all agree to this...who ever wins this months MMC do the one Nigec wanted to do for the SMC...kinda sounds cool to me as well. This way Nigec can get a new idea for the SMC.

LeonRegis · Post by **LeonRegis** » 28 Sep 2010, 02:17

This one is already good, but there's no prob on nigec setting a new one... now that I'm back on action I think a good start would be a SMC!

LeonRegis · Post by **LeonRegis** » 29 Sep 2010, 00:29

So it has been extended, or a new one will be created?

I want to start on it!!

MikomDude · Post by **MikomDude** » 08 Oct 2010, 09:22

That's a cool animation, I never really got the hang of the wind in the TS physics engine but it looks like you have

PS, when adding a YouTube movie to the forum you only need to enter the id-code of the video, for your video that would be "2Br3Qs0TiwI".

see?

theuns · Post by **theuns** » 08 Oct 2010, 10:02

ahh, thanks MikomDude... didn't know that about the youtube tags

nigec · Post by **nigec** » 08 Oct 2010, 10:12

nice one mate

rjeff · Post by **rjeff** » 08 Oct 2010, 20:03

Ok I am in on this one. I already have one in the works.

rjeff · Post by **rjeff** » 12 Oct 2010, 00:57

Here is mine. I have alot of ideas, but I had to do a quick one.

nigec · Post by **nigec** » 12 Oct 2010, 08:52

nice one rjeff

Should we give it until the weekend to see if there's any more?

MikomDude · Post by **MikomDude** » 12 Oct 2010, 10:09

Man, that's excellent! It's a perfect way to demonstrate the TrueSpace physics engine.

nigec · Post by **nigec** » 12 Oct 2010, 10:50

I had a spare hour or so so I had a go with Awakening, its kind of a game as well you have to drop the ball (left click) and get it into the cylinder

MikomDude · Post by **MikomDude** » 12 Oct 2010, 10:59

Hey, that's cool. How did you make that? I there a special addon for TrueSpace or..?

btw, here is me losing big time...

nigec · Post by **nigec** » 12 Oct 2010, 13:06

No Awakening is stand alone, you can use models from TS, my lttle game used Sketchup geometry, but TS models usually work better.
You can check out Awakening here:
http://www.awingsoft.com"
the physics system is no where near as advanced as Truespace and needs to be coded, .. well it probably is more advanced but I wouldn't know were to start coding something really complicated, dropping balls and waving flags is about my limit lol
My first try didn't have the ball drop thingy moving and it was very hit and miss to whether the ball went in the tube
You can load the game into Awakening and replace models, you need the geometry for the ball spawning point.
I'd use 3DS from Truespace, import the model as a Mobile, scale it so its the right size then convert it to a surface

or I could do a tut to how its done

MikomDude · Post by **MikomDude** » 12 Oct 2010, 14:07

A tutorial would be nice, I'd like to have a "gamemaker/world" where I can use my models.

froo · Post by **froo** » 12 Oct 2010, 17:48

I made a pumpkin in tS this morning; hope to make a pumpkin projectile; started making some candy corn to knock over but had to get to work. Maybe I can work on that tonight. mmm Pumkin launcher! If I don't make it though, then carry on!

hehe hm.... jack-o-lanterns a-falling...

nigec · Post by **nigec** » 12 Oct 2010, 18:50

cool Froo, take all the time you need..

There's already a tutorial over at Awakening:

Cool, thanks!

Accu · Post by **Accu** » 13 Oct 2010, 15:58

Speaking of projectiles...
This is tS6.6 physics, with all the bugs you can imagine. Still, it's fun to get spheres to fly (or is it just me?).

Accu · Post by **Accu** » 13 Oct 2010, 16:17

And another one.
If the image appears black, click on it, it's there. I don't know what happened when I uploaded.

froo · Post by **froo** » 13 Oct 2010, 16:24

Cool Accu!

Accu · Post by **Accu** » 13 Oct 2010, 16:28

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.

).

froo · Post by **froo** » 13 Oct 2010, 16:46

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!

Froo

rjeff · Post by **rjeff** » 13 Oct 2010, 17:03

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.

froo · Post by **froo** » 13 Oct 2010, 17:15

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

I like the cannon especially.

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

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
