Comments on: Verlet + Newton + FP10 = Cloth Simulation

Albert: Not really, the implementation of the Verlet physics only uses 1 iteration for performance, to keep the distances between connections correct (and as such not deforming the cloth), more iterations would be necessary but it could easily get too slow.

Hi,

is there any way to increase the falling velocity without “damaging” the final shape of the cloth? I’ve tryied chaging the _gravity var, but somehow this seems to modify the final width of the cloth… Thank you!

Claudio: You can probably achieve that by removing any special cases using “if (y == 0)” in the class Curtains.as. I don’t think the results will be very spectacular, though

hi,

is it possible to NOT FIX the top!?
i need a simulation like DRAG CLOTH FROM A TABLE …

would be great to get some hints
cheers

@Sander :

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest(“your image.jpg”));

function onComplete(e:Event)
{
//– and there is your bitmap…
var bmp:Bitmap = loader.content as Bitmap;
}

Hi
Did anyone successfully imported this into CS4 yet?
I’m not sure how to do this using my own BitMapData.

Thanks for your help!

Mr King: Sure you can. You might want to get rid of the line “import __AS3__.vec.Vector;” in Curtains.as (it’s a Flex Builder 3 issue using FP10 Vectors). Just extract everything from the CurtainsDemo function in the main class and use your own BitmapData.

Can I use this somehow in Flash CS4?? Im just a flash CS4 user for a few years now and never attempted to try Flex.. Can someone please give me some advice because thank

Hamid: It’s not supported, but you could easily hack it in. In the method “findClosestPoint” within the “if (dist < minDist) {” block, you could add:
u = i*_bitmapData.width;
v = j*_bitmapData.height;

That should give you the bitmapData’s coordinates of the vertex you’re dragging.

Hello David , thanks for writing this nice code

I have a question : how I can find the original position of dragged vertex like that u and v properties of TestPoint2D method in ViewPort3D class in Papervision3D ?
