Fabric Weave (On Cable)
show user profile  FX
I'm having a hard time trying to figure out a way to realistically model woven fabric on cables.
I know this can be done using maps and displacement but client insists it's modeled.
I've done the internet...twice...spent hours searching and trying different methods and failing every time.

The closest I can get is by using a renderable spline, flipping the edge direction and creating splines from the new edges.
What I can't figure out is how to select every other vertex and scale evenly in or out so they create a weave, (I don't even know if this is possible)

Another problem is i can't alter the interpolation of the splines i create from the flipped edges, changing the verts from corner to smooth makes no difference to the shape.

I tried rectangular rendering method on the spline, i was hoping to select every other face and extrude them out to fake the weave, but there's a gradual rotation of all the splines and I can't figure out how to get them uniformly aligned so i can try this.

I haven't seen this method used anywhere to create weave, I was hoping some of you guys could suggest a better way using this method.

The whole thing has driven me nuts over the last two days, can anyone suggest anything ? I've been staring at this too long.... lost my mojo.



This is the effect I'm looking to create...

hope this dont sound daft but couldnt you use a snake skin displacement map then convert displacements to polygons and work from there?

Thanks debs, yes that would be a good approach.

My patience cork has popped!
The clients going to be told what he's going to get, the end product is going to be manufactured, all the loom operator will need is a pattern, of which there are a gazillion generators out there, and software packages the loom operators use.

Maybe just crossed wires with communication, he doesn't really *need* this in 3d , a 2d displacement will suffice, and a tiling pattern of the weave, I can even supply the file type the loom operator uses.

I need a slap on the back of the head now and again....step back, deep breath, re-approach :)

Makes me think of carbonfiber.

If I was to go about this my gameplane would be this.

1. If I was to model it, I would model one of the boxes of fabric, then mirror it and make it offset with a tile placement. Then get that to tile. Bend the pattern 360 and now you have a base for a rope. Now just copy it upwards and duplicate as much as you need for length of rope. (By now you will kill your pc)

2. I could also model it but make a perfect tileable displacement using my model and then just texture a cylinder with that.

3. Just use a map from internet and call it a day.

The topic rang a bell and... well I'm baffled I could actually find the picture. It's from 7 years ago!

i'd be temped to model the material flat then bend 360 so it's a tube then add a pathdeform mod
might cause some stretching on corners though

Very helpful guys, thanks, probably just go with a diffuse bump approach, I'm using this to generate the patterns...

@ Garp, I saw that tut but must have been tired, didn't really look into it, but it looks a perfect method as a base to start on, thanks.

Interesting post :)
Deb i never knew that it was possible to convert displacements to polygons, i am gonna google this technique but if you guys have some nice link for this technique(displacements to polygons) share please

This garp guy :D i think when everyone on this forum is stuck at some point, this man help out everyone. Cool tutorial you have shared@garp

Grotey, yup i never used displacement modifier and then adding a map to it.
This is the tutorial "" :D Thanks guys

Cool, but is it possible to do this on a curly wire like Garps post above ? I had a dabble but it doesn't seem possible when using real world co-ordinates on the cable...not enough uvw options in the displace modifier ?

Just came across this little script... currently for fencing but may be developed for other "weave" styles.
