FrankenSpline... Open Source Figurine

[Chris Botha]

Guys.. I am tired of modelling blobby toy type stuff so I am attempting slightly more realistic models.. and I am kinda runnign in walls.. I want to model a hand because of a headache a fellow forum member is having, or just for kicks, and this is my workflow idea...

I figure that since fingernail area is probably hardest area to model right I will model only one finger, the longest middle finger, then copy multiples and of it and scale them appropriately.., draw a hand body with thumb then bridge the fingers onto the hand..

SO.. this in mind I started out the project and got stuck on the knuckles..

I grabbed this reference image,

finger_anatomy_article.jpg (14.52 KiB) Viewed 2361 times

did an extrude base and poked and prodded till i got what I needed in terms of shape, some extruding to do the fingernail area to arrive at this,

and then tried to add creases, wrinkles, over the knuckle area.. FAIL...

the whole model starts going wonky when I attempt this.. the finger starts looking like it was in a grenade accident...

In your own time (no rush, I don't make fingers for a living) could someone grab the model, and add some wrinkles over the knuckles with a few screen grabs of how you added them?

Thank so much

Regards
Chris

I am the first person to advocate using the right tool for the job.. if this is the kind of thing that should be finished up in Zbrush etc just say so? I don't want a harder solution when a simpler one is available, or make you jump through hoops for no point. If its easy and I am just overlooking a simple way to add these creases in tsplines then please help, otherwise no worries

72 views, 6 downloads.. no comments.. guessing its off to zbrush hehehehehe..

FWIW i poked at this for a few more minutes this morning. its a waste of time project as i have no use for the model, but the workflow proposed above works pretty well..

copy paste bridge... all up about ten minute to from finger to hand..

I love tsplines.. so simple, but so powerfull... I am quite sorry I did nto persevere in V1... If you asked me 4 weeks ago if I would be able to modea hand.. i would have laughed at you.. now it seems easy.. even if it looks like a slightly arthritic orangutangs hand.. thats jsut practice to get it right

This software must be one of the best investments I have made since i got into the cad game.. worth it at even double the price..

I'll just chuck in pair of cents -- I don't think it's going to be particularly easy to get those knuckle wrinkles using T-Splines. I'm pretty sure it's at least *theoretically* possible. You'd want to run isocurves along the path where you want the wrinkles, and then push and pull those isocurves to adjust them -- but really, the right way to do that kind of thing is (IMO) an offset map, or something like Z-brush.

While it is my secret desire to make T-Splines capable of doing everything everywhere, I don't currently have a good answer for how to get T-Splines doing that high-detail stuff that Z-brush is so good at. It's actually a question of speed -- the huge innovation in Z-brush is that they figured out how to do immense subd surfaces extremely quickly, and then came up with good tools that all assume you're manipulating surfaces with millions of control points. It's still a stretch to use T-Splines in the 100,000 point range, and we have some limitations from just plain being more complicated then a subd.

Oh, one other quick thought -- you could probably get those wrinkles from a texture applied to the final model after the fact. They wouldn't, strictly speaking, be wrinkles, since they'd only be painted on, but for many use cases it's sufficient to just look right .

Good , thanks for reply.. old adage applies.. you wont use a screw driver to hammer nails..

I had some reasonable success after converting to nurbs and using standard ffd and a liberal dose of cageedit.. .. the model was actually started to try help a forum user from a different forum who was unable to get tsplines to work well enough for him in a certain scenario..

I think application of time and energy was the issue, not tsplines

Personally, I think you guys should do some branding.. like intel.. "T-Splines Inside!" stickers.. I would wear mine on my pc with pride!

Nice finger/hand Chris.
So I go and download the finger model - and sit inside on a sunny Saturday for a couple hours playing with it. No regrets, however, V3 is a blast.
Anyway, attached is where I've taken it. I don't get enough opportunity to play in T-Splines, so this was a great chance for me to get into it.
Amazing file size for so much information.
Open-source-human models beginning here?

Cheers!

Cannot wait to see

can you resave in rhino4 format please ?

also by the way I stumbled into nice anatomy reference resource..

[ernchesto]

Sure thing.
Yeah, my playing was far from scientific! But this seems to be a real strong point of T-splines - the ability to collaborate on models.
Attached is the v4 version.
Funny - I'm unable to toggle it into box mode...
Cheers

[Chris Botha]

wow! Thanks so much for sharing that.. your arms looks quite a bit more professional than my finger tho , i had planned to abandon this, but i think when i have some time spare I wil revisit anatomy.. i see that teh arm, if reproportioned correctly could be a leg too.. its all a question of how you look at it.. hmm all new doorways opening...

i could toggle to box mode.. quite aggresive look in box mode, kinda like the dracula dudes body armor in Blade3

open source body model, everyone adds a part.. Tsplines frankenstein!!!!!!

[ernchesto]

Thank me? Thank you! And it's certainly no more professional..

FrankenBSpline Yowza.

I don't know what's up with my box mode toggle...I'll have to experiment more.

[Chris Botha]

I will try working on foot.. deriving the leg from your arm addon.. and reconfigure the hand into a foot.. for now i donate a pair of loafers, just in case my foot looks like my hand

I invite anyone else to modify this original geometry into further body parts please.. would make an interesting project!

[Matt Sederberg]

I'll contribute a skull...modeled by Juan, lightened up by Travis.

[ernchesto]

Excellent! Thanks Matt, Juan and Travis.
That seemed to be just what I needed to start putting it all together. I think it's coming along really well (despite my nasty twists and creases, etc!). Chris, do you think the cobbler is available to make some quick tweaks to the loafers?

On a more serious note - I was able to use my newly learned skills from Sky's recent webinar to fix up some issues I created in this model, and many others. Great webinar - thanks. You folks are doing a really great job with them, and they're much appreciated.

Cheers!

[Chris Botha]

woooooooooooohooooooooooo looking great guys!

I dont want to spoil those feet man.. i think I might have to work on some things instead!

[josef1]

Thought I would have a go at an ear,well to be honest it started out as a belly button

[Chris Botha]

weird.. being a well rounded pervert, i usually start at the ear and work my way down to the belly button

Hi!
I found this hand somewhere in web, and it is not T-spline made model, but it works with t-spline commands so we can look at the structure. Such type of structure is usual for mesh modelling, how do you think we can do it by t-splines?

These forms can be modeled using T-Splines. No Ploblem!
