folded or crumpled textile

[Anonymous]

Hello
How can I make in 3D a folded textile, and a crumpled textile ?

Thanks for your help!

You have 3 options as I see it.

1. Use a material/fill pattern on an existing object/tool.

2. Find someone who has or will make an object that is what you need, this will probably require money.

3. Make the object yourself, if you are not good with GDL you could try playing with profiler or the mesh tool.

It really depends on what you want it for and how detailed it needs to be.

Ditto for the net in the other post.

Thanks for your answer.

If I use an existing textile I have, what do I do with it? Do I scan it? And then? I put it on a wall as a material in archicad?

thanks again to help me

PS: by "material" I mean 'texture'......

I am probably not the best person to answer this, but I will have a go.

If you scan/ take a digital photo of your material you can take it into photoshop or similar and create a texture out of it. I expect books on photoshop, in most Uni libraries will help you if you can't get hold of Dwight's book 'Illustration in Archicad'.

The simple bit is attaching the texture to a material and placing it on a wall.

You could also put an alpha channel in it so that you can get some nice bump mapping action.
mmmm.... textiley

You might try looking here:

More specifically at at product called Foldtex, but Mr. Brownell has collected a very wide assortment of materials for possible architectural use.

This is a quote from his pdf catalog

"TRANSMATERIAL
A catalog of materials, products and processes
that are redefining our physical environment."

Happy hunting

Hi Charlotte,

You want to distinguish the shape and the appearance of the surface.

For the shape, you will likely want to use the mesh tool. If you have the Cigraph ArchiForma 2 add-on, you can easily create some other appropriate shapes.

I have some experience scanning and photographing fabrics since my wife is a weaver and I have done some machine knitting. My experience is that scanning provides unsatisfactory results because of the reflection of the scanner bulb on the fibers. Taking (digital) photographs without flash is much more satisfactory.

You will have to turn your picture into a tile-able image ... one that can repeat vertically and horizontally. As others have said, Photoshop is where to do this. Because of the nature of fabric, it is most helpful if you have a swatch that you can pin (block) onto a board so that is perfectly square, but otherwise you can remove distortion in Photoshop. (For woven fabric, the weft and warp threads must align exactly when tiled, for example.) You must photograph at least one complete repeat pattern if the textile has a repeat (whether in color or texture). This is all pretty easy once you're used to it, but might be tedious the first time.

Create a new material with the resulting image as the texture file and apply it to the mesh or other object.

Have fun,
Karl

I must say I have never understood how you get a pattern to repeat ( and I still dont ) any advise would be greatfully received

Hi John,

From your past posts, I think you do? So, maybe I don't understand the question. Maybe you are talking about textile repeats and not texture images?

The repeat of the image file is of course done automatically by ArchiCAD: whatever image is loaded for a material is repeated indefinitely vertically and horizontally. (In Piranesi and Artlantis, we have the choice to repeat in only one direction or none.)

Visible repeats are of course the bane of most materials - grass, wood, stone, etc.

Patterns in textiles are discrete - picks or stitches (think pixels) - and most conventional techniques result in a repeat. (Free-form patterns - intarsia and overknitting for knit fabric, and drawloom and tapestry techniques for woven fabric are an exception of course.) Because of this, it is easy to crop and touch up an image of a textile to make it repeat perfectly.

Cropping an image of a wallpaper pattern is similar. To make it repeat perfectly requires a uniformly lit image greater than the repeat and cropping (at pixel level zoom) to exactly where the same pixels from the left appear again on the right, and from the bottom appear at the top.

But, that's probably not what you were asking...?
