    You know, it occurred to me that perhaps you might actually develop a dynamics engine for DAZ Studio that can take simple obj's and drape them and then work up to more complex or outfits that were previously made. One of the factors that is gravely missing from DAZ Studio is a way use common and complex shapes to drape at the end users convenience rather than relying on that other system (which to me is too limiting).

    the version i'll publish soon will be for "normalized" wrapper sheets/tubes
    by normalized i mean -- ( like the primitive planes, and the tubes seen so far ) : rows and columns having a constant number of vertices
    maybe later i'll add gravity which should give us interesting draping. but it wont be truly dynamic with interactions between constraints

    non normalized wrapper objects are supported for the shrink process but not for the spandex effect
    because my script has to analyze them and locate the rows, columns and rings of vertices before stretching them
    and for now it can only figure easy stuff like grids

    somehow related to the shrink wrapper

    with this topology ( architecture )

    if i add selection-by-material ability to the script ( think i will )

    then this could be treated as 3 grid-planes

    with different material assignments, or it could be seen as 3 tubes

    though my model is already well fitted, maybe a little shrink wrapping would add some credibility/realism

    Very nice! How about a nice tank top to go with the panties? :-)

    Mostly Harmelss ( working title was mcjAnnoy )

    will probably try to publish the new shrinkWrapping script this weekend

    with an eye on usability for minimally complex structures like the short pants

    in this case, i modeled them over an exported Aiko3, with her spandex" morph set at 67%

    then i used mcjShrinkWrapA to push it onto Aiko

    but for the next version of mcjShrinkWrap i'd like to be able to shrinh/drape/spandexity sections of a garment

    Coming along very nicely!

    I've been absent lately. Been setting up my shiny new Windows 8 installation.... Just today getting back to things like attending my Marilyn M morph for Dawn. YAY!

    well maybe someday i'll do just that, but i don't really know the modern rigging ways applicable to Aiko3

    been procrastinating on re-starting work on the shrink wrapper+spandex but i 'm pretty sure there will be advances this weekend :)

    in other news i learned the terms "high waist cinch belt" and "high waist sailor shorts"

    lol ... not worried about the rigging! For some reason I have not quite got the nack for making the mesh on shorts fit that neatly. That's what I referring to.

    Modern rigging as far as I'm concerned is to throw something on Genesis, and use the transfer utility tools. For A3, I have the clone.
    [edited out by me - I got the FS tools for legacy working again ... and it was my fault that it wasn't.]

    So, no rush, when it's available, as long as things remain stable around here, I would follow beautiful tutorial on how to make nice neat shorts ;-) And rig them.

    ( well i did change 1 line of code while making the belt/high-waist pants

    thanks, i think what i really need is the stretch/folds/wrinkles in the fabric to make it look more like fabric

    Haven't got the texture on this computer, but am working on something that produces lots of nice wrinkles in any cloth!

    Skirt and belt part basically done ... hope you like purple.

    thanks, i'm slowly restarting work on this, it's the last mile ( saying that but there's probably 5 miles to go :) )

    Figure 3 - current work is to make the script usable with any orientation of the shrinkable cloth

    Figure 5 : mold/press stretch-Y stretch-X

    geometry in 3D space is hard ! ( dont worry the floor is cushioned ) ... having issues when i try to project curved cloth ( like a section of a cylinder )

    Figure 2 - in green and red the "convex hull" process , which is used to make cloth look as if it was under tension

    thanks!

    today i work a bit more on the case of grid-like cloths
    shown here is the easiest case where there a wall behind Aiko, so all collider "rays" hit something

    Interesting, how does the calculation know to NOT press/bend between the legs, but it does press/bend under the breast area?

    there's 3 phases ,

    -shrink-wrap ( project the cloth )
    -stretch the horizontal threads
    -stretch the vertical threads

    in this last picture i didn't do the vertical stretching, else it would look like

    I've been thinking of ways to add belts, a bit like in Poser Cloth simulation, you can have groups of vertices that are like glued in place

    and i may use the surface textures as the way to specify what gets simply shrink-wrapped and what gets the spandex effect

    in the example below,

    the yellow ( red + green ) vertices will be Shrink-wrapped And Horizontally spandexified
    (like a tight skirt )

    the white ( red + green + blue ) vertices will be Shrink-wrapped, Horizontally spandexified and vertically spandexified
    ( like a rigid belt )

    the magenta ( red + blue ) vertices will be Shrink-wrapped, And vertically spandexified
    ( like uh suspenders )

    in another thread i posted a free script to create primitive planes that are better suited for the mcjShrinkWrap tasks

    i got diverted in the physics simulation project
    ( https://www.youtube.com/watch?v=0l6GdTCLSWs )

    but will come back to this one,
    the lattice-deformer prohject

    and the mcjTeleblender project

    soon'ish :)

    Wow, this is getting close to Marvelous Designer cloth simulation. Almost to the point where it will work with patterns! Amazing work.

    SAFE 2019 Update

    Q. : Do you really need to update?

    A : With the old version of this script if the wrapper object was a subdivided surface, and you saved this scene as a .duf file, the scene  file would become un-openable !!! 

    A : The new version has 2 new options and 2 help buttons

    A: Since mcjCollider is now Mac compatible, Mac afficionados can now use this script !

    uses the services of the free mcjCollider
    plugin to shrink wrap tubes around figures and objects

    it's ready ! https://sites.google.com/site/mcasualsdazscripts3/mcjshrinkwrapa

    also see these brand new scripts
