Hi

Sorry for the bad quaality of the picture but I think it can help to explain what I want to get.

I have a mesh like the number one, but I need the wireframe the way it's in the picture 2. It's a bandage over the bottle. Any idea how to get it?

Use the exterior loop of the first as a drill into a mesh like the second. IOW, a 2d boolean (that's what 'drill' is).

You could use heat shrink to conform a mesh of the second kind to the first.

Well, as usual I didn't explain it correctly, sorry.

I need a continuous band with the borders very close, covering the bottle but without overlaping, like a peeled apple but very uniform band to extend later. What Erikals linked might help: I'll take a look

Thanks for your help

Make a cylinder in Layer 2 slightly larger than the bottle, then use a combination of Shear tool and Heatshrink to wrap the bottle. Slice polys at appropriate points top and bottom. 3dpowers have a Heatshrink plugin on steroids. It costs though.

You could also try spline patching concentric circles down the bottle, a basic form of retopologising.

Heat shrink sounds good (I don't have it).

You could also just make a spiral cylinder and get your bottle shape with tools using falloff or weight maps.

Except for the native one, right?

Thanks everybody, very nice tips. I think using heatshrink and the plugin Erikals showed us in his videotut works good.

Now I have to get the bandage covering the bottle from the beginning, so I think using a backwards video would be the best way. I "only" need to undo what you help me to do: unwind that bandage

Took a quick jump at it anyway for my own curiosity's sake.

So, was that with KO Pointfit or what?

Pretty impressive: can it animate??

No, no Pointfit. The "DOH" is because I'm on Mac.

I just extrapolated on the method i started above. It's just a pose using weight maps etc.
To animate... hmmm. Guess I'd do it a bit different.... use geometry to make a path to create a bone chain and, eventually, IK.
Then, I think, you could just "peel" it back off of the glass..... carefully. :hey:

Just playing with textures here....

Joe, several questions, but first: I missed your post #8 , so backtracking a bit..

Heat shrink sounds good (I don't have it).
You could also just make a spiral cylinder and get your bottle shape with tools using falloff or weight maps.
Is that a Curve shaped into a bottle shape (or a curve picked off the points of the bottle), and then used as an extrusion Path?

'Cuz I was wondering how you got the edges to meet so perfectly?

And in your msg #17 you say:
"a pose using weight maps etc"
but....1) a 'pose' ???
2) by weight maps do you mean you used w.maps in setting the falloff of the tools, or what?

Sorry for the 3rd degree, but I'm baffled. Very inspired by the example though.

1) It's a regular tube 119679 offset in the Y using Move and a weight map 119680.
Finish off the ends and you have a tube made of continuous spiral geometry 119681.
Using stretch (in top view) a few times with various linear falloff can get you a complex bottle 119682.
So, in this case, the bottle itself is made of the strips you need....Just pick the strips you want right off of the bottle, copy and thicken 119683.
-------
Pose means the strips have been manipulated in modeler (some by hand, but mostly with weight maps 119684 119685 and are in their final "pose"(itions) ;).... not through anything in Layout. To animate, like I said, I'd use the strips to make a bone chain and use IK.... I think. :)

2) Yes. :beerchug:

Thanks for doing all that screen grabbing! Very helpful.

I'm guessing the w.map on the tube is gradated from zero >100 (it's a bit hard to tell from the image). Did you start with a flat rectangle and weight gradate THAT, and then bend it into a tube before offsetting, or do you know some slick trick for getting a gradated w.map on a tube?.......... Oh, I see, you most likely used UV>>W.Map, and unwelded the seam blah blah blah. Nifty!

119690

Yes 0>100, but not from flat geometry or UV.....way too much work for my taste :D. (although those techniques come in handy as well, of course).

But seriously.... don't know what I'd do without Weight Outward (https://www.lightwave3d.com/assets/plugins/entry/weight-outward/)!!!!!
Just grab a couple of points and tell it how many steps you want it to go. :hey: (you can even use a background spline :thumbsup:)
(Weight Extend is pretty cool too)

edit: on the tube, yes, I did unweld a seam for the gradation to go all the way around. On the strip ends..... no need to (if I had to unwrap/UV those..... what a pain :sleeping:).

Maaaaaaaaaaaaannnnn, I gotta COUNT??? (just kidding)

I felt pretty guru-ish, but really, "UV>Weight" is a total doddle.

I even put a SECOND gradated w.map on the same geometry to size down the top rows. ("He's a witch!!!") Playin' above my game, really.

:looklooklook: That "Background Spline" option is very intriguing-- basically you can make a WEIGHT PROFILE that Weight Outward then applies to your geometry, no matter how it twists and turns. Interesting.

Back to the OP....

Vector,

Hope it's coming along. I know you were looking for one continuous spiral loop effect.....
But just wanted to also mention Sketch Mesh (https://www.lightwave3d.com/assets/plugins/entry/sketch-mesh/) (only 32 though...maybe there's an 11.6 retopo native tool?)
You don't have to change the poly flow of the bottle at all, just draw over it.
Could work for long spirals, or, for added complexity..... strips on top of strips etc.

Below: both strips done with Sketch Mesh (vase by jeric synergy).

This, Sketch Mesh, would be a prime candidate for a Kick$tarter campaign to port to 64 bit.
