Noobini Posted December 9, 2017 Share Posted December 9, 2017 so I won't look like a dill, I've searched the forum for Inflating Cloth...can anyone tell me if it's possible WITHOUT resorting to FEM ? It's a simple concept, have a sphere, ie. balloon, inflate it, blow it up (not to smithereens, just volumewise)...can't be that hard ? Yes. I've worked it out but as said, don't wanna look like a dill so could someone please confirm for me if it is possible and sooooooo easy that I might have missed something so obvious... No FEM please.

toadstorm Posted December 9, 2017 Share Posted December 9, 2017 (edited) you could try approximating cloth with pop grains. check out the granular sheets example for ideas on setting up constraints. then just apply a force on the points pushing outwards and hope your constraints will deal with it. you could break constraints in a sop solver if you need popping action.

Noobini Posted December 9, 2017 Author Share Posted December 9, 2017 JUST Cloth...why am I being pedantic ? coz it's an extremely simple concept. Quote Link to comment Share on other sites More sharing options...
Noobini Posted December 9, 2017 Author Share Posted December 9, 2017 here's proof I can do it using JUST Cloth...but please someone tell me "yeah it's always been possible like this or that way using just cloth".....show me... My Cloth below doesn't even have to be watertight...I clipped the bottom off...still works... Quote Link to comment Share on other sites More sharing options...

toadstorm Posted December 9, 2017 Share Posted December 9, 2017 i hate to break it to you dude, but cloth IS fem. look inside the solver. Quote Link to comment Share on other sites More sharing options...
Noobini Posted December 9, 2017 Author Share Posted December 9, 2017 (edited) ok then, why do all previous attempts call another FEM solver instead of using what's already there that you point out IS FEM ? (tho I could argue, yes, it's FEM but its Solver Type is Cloth NOT Finite Elements...but whatever, I've worked out my simple way of doing things.....when I get more experience, then I'll throw in more advanced nodes) Edited December 9, 2017 by Noobini Quote Link to comment Share on other sites More sharing options...
Noobini Posted December 9, 2017 Author Share Posted December 9, 2017 (edited) here's my file for all the noobs out there...this is one way to inflate Cloth using JUST the clothsolver. It's my way of learning Houdini Cloth. If experts want to yell at me: - hey noob, you're not using any sopsolver - hey noob, you're not using any multisolver - hey noob, you're not using any grainsolver - hey noob, you're not using any FEM (you're right, my clothsolver is set to Cloth) - hey noob, the clothsolver is damn slow ....don't worry, I got zero experience to argue with you...I'm just sticking to the title in my thread...is all Any tips on how to speed up the sim (clothsolver) are greatly appreciated. vu_BlowMe.hipnc (zip file contains filecache) vu_BlowMe.zip Edited December 10, 2017 by Noobini Quote Link to comment Share on other sites More sharing options...
