MAXScript Cloth Simulator

looks cheesy, lol like a piece of cheese flying around

Solozar, glad you figured it out. :-) I am sorry but since it is just a little experiment I don't plan on creating a UI unless I turn it into something that is more universally applicable. For now I leave the UI to somebody else who wants to play with it. :-)

Has understood.
But it is difficult to understand a script and to change tinctures.
In the future will be UI and so on?

In advance sorry for my English.

I had a problem. In any way load the script also writes:
Unknoun property:"numverts" in undefined
How it is possible to avoid the given prolemma?

Martin: You are right, the dummies have to be created as well. I missed that one.

Jeff: Haha, good point ! Yes, I admit it !!! I toook Skeel's OOP concepts and transferred them 1:1 into MAXScript. Actually that was the first time I used structs which - compared to C++ - is kind of a mess right now (if you want to hear my opinion). It would be nice if MAXScript supported inheritance and polymorphism as well but maybe that comes later at some point... ;-)

Anyways, I can't give enough credit to this tutorial. He has structured it in a way that is very easy to understand and he explains everything in a simple way. And these concepts apply to rigid body simulatios as well. Sum up forces, integrate, done ! Pretty simple actually if we ignore collision detection for now... I can only highly recommend to look up his tutorial.

I am going to try the Runge-Kutta (RK4) integrator next which seems to be the industry standard in simulations. And my ultimate goal is a simple simulation system that I could use for characters, cars, planes or boats to automate certain things. I will keep you posted ! At some point I will have to convert to C++ though because MAXScript is just tooooo slow :-) Hehe !

really cool script! it's also really interesting to see the transition/comparison of the XNA code to maxscript code. thank you very much for this script.

Thank,

your explanation worked perfectly , I'll also add that you have to create $dummy01 and $dummy02 at the vertex pos :-)

in fact , I like hard to use tool too :-)
nice work on this one :-P

Hi Martin,

thanks for having a look ! :-) No plugins needed !

You should be able to get it to work by changing two things in the script under INITIALIZATION (line 531 - 561). You have to set iWidthSegments and iLengthSegments to 12 and in line 553, you have to put the name of your plane. The last thing is line 561/562 where you set the names of the dummies and the vertex number of the constrained vertices for attaching the corners (in your case probably 1 and 12). That should work. It is important to get those segment numbers right otherwise the springs between the vertices will not be initialized the correct way. If in doubt, try it on the max file I provided here and go from there.

Sorry for hardcoding all that stuff. I know it makes it hard to play around with. But my time is pretty limited right now so I had to focus and didnt have enough time to build a fancy UI :-) I hope you can understand ! :-)

I've got a simple 12x12 editpoly plane and it crash at line 248 unknown pos in undefined , do I need special plugins installed ?

look very interesting by the way :-)
