Iain Denby Posted July 7, 2004 Share Posted July 7, 2004 Hi guys I have a project coming up whic requires me to model Tensile Fabric structures. Any ideas as to the best approach to model the fabric? Link to comment Share on other sites More sharing options...
STRAT Posted July 7, 2004 Share Posted July 7, 2004 i usually use surface tools. Link to comment Share on other sites More sharing options...
Iain Denby Posted July 7, 2004 Author Share Posted July 7, 2004 i usually use surface tools. Yeah, I've just been experimenting with this. 5 sided curved shape at the bottom, a circle at the top and an inbetween shape in the middle. Add a cross section and surface modifiers. Is this what you mean? Link to comment Share on other sites More sharing options...
STRAT Posted July 7, 2004 Share Posted July 7, 2004 nope. wasn't thinking of cross section method. more the splining method. literally building up the shape in splines and letting the ST modifier do the rest. i've done this a few times before and i really got that nice stretched-fabric-over-a-frame effect.

3dp Posted July 7, 2004 Share Posted July 7, 2004 i'd also give nurbs a mention parametric is built in so as long as the designer has it right the rest will be a breeze having said that lofting maybe also suitable basically whatever you'll need a spline cage as a start Link to comment Share on other sites More sharing options...

I think Spline cage is probably the answer for me. Link to comment Share on other sites More sharing options...
tcorbett Posted July 8, 2004 Share Posted July 8, 2004 Nurbs!...I don't go there. LOL. I used to be that way, but finally saw the light. NURBS may take a some serious getting used to, and certainly the word "Rational" appears to be a misnomer. Once you get the basic concepts down, you will wonder how you ever lived without it. They should be a good fit for your project. Link to comment Share on other sites More sharing options...

They should be a good fit for your project. must admit i've never used viz/max NURBS, purely because i've never needed too, but i do use it in C4D occationally these days. they get a shed load of bad press, and i was always on the understanding that viz/max NURBS are crap, unstable and generally a pile of pants to use. you obviously dont find this the case. what's your opinion on viz NURBS then? only it certainly wouldnt suprise me if they're allot more stable and usable than max's.

pcote4 Posted July 8, 2004 Share Posted July 8, 2004 I had a tent project like this some time ago and I used the demo version of "Patterner" (http://www.patterner.co.uk/). The demo version has dfx export disabled, but vrml export worked. I also used Rhino for some forms. Link to comment Share on other sites More sharing options...
tcorbett Posted July 9, 2004 Share Posted July 9, 2004 ... what's your opinion on viz NURBS then? only it certainly wouldnt suprise me if they're allot more stable and usable than max's. I've only ever used NURBS in VIZ, so I don't know how it's use of them stacks up against other applications. I would imagine that MAX & VIZ share a similar functionality. As I said, they certainly are not easy, at least in VIZ. It is still "touch-and-go" for me depending on the circumstance. However I found that once you get the hang of the quirks, they become invaluable, especially interior renderings. I constantly use them for smooth, non-linear surfaces such as curtains & drapes, some pieces of furniture, beds & pillows, glassware, vaulted ceilings, etc. I have found it much easier to simulate realistic effects with these than with polygon modeling. Again, there is probably a better product out there for NURBS (I have been hearing great things about MAYA and RHINO) but i have not had the opportunity to work with these yet.

bigcahunak Posted July 16, 2004 Share Posted July 16, 2004 Dibbers I always enjoy your work. While this one isn't here for c&c... I'll still add some (shut me if its not in place) The tensile looks somewhat too stiff. The trees in the background looks a little too big, and Their reflection is missing in the lake.

STRAT Posted July 17, 2004 Share Posted July 17, 2004 Dibs - great image man i'll see if i can dig out some of my stretched fabric structures using the same modelling methods. Link to comment Share on other sites More sharing options...
Iain Denby Posted July 18, 2004 Author Share Posted July 18, 2004 Dibbers The tensile looks somewhat too stiff. The trees in the background looks a little too big, and Their reflection is missing in the lake. Too stiff? isn't it supposed to be under tension? Yes, the trees are probably too big, but I was more concerned with them towering above the structure to add contrast. You're right about the reflection, I'm ashamed to admit it, but I forgot to put it in! Having said that, they don't appear as much as you may think, because of the slightly elevated viewpoint and because they are set bach in the distance. Strat Thanks man, it was your suggestion that made me experiment with this technique for the first time. BTW, this is image is just and extract from the complete image.
