[Plugin] Super Drape

Dave R · 4 Oct 2011, 23:34

Curious. I drew the curves by putting arcs on the sides of a large box. Then I used Fredo's "Skinning of Shapes" tool to create the skin. I saw there were a few diagonals that weren't drawn in but I figured since the surface skinned over alright, they weren't needed.

Fix it and I'll break it again.

Awesome, TIG!!!!!!!!

Brilliant, thanks Tig.

Thanks, TIG: Works great. On an object the text or texture is copied on the top and on the bottom (almost)!

I'm looking at trapping faces that are looking away from the draped group...
Meanwhile some careful erasing should fix it ?

Thanks TIG.

Thanks TIG.
In kirill2008, there is a similar plug-in on your, "Lss_Tool_Bar"

TIG, thank you very much.

Here's v1.1 http://forums.sketchucation.com/viewtopic.php?p=358314#p358314

Face 'pairing' of materials between the groups is now more robust, consistent and very unlikely to fail.
Only topmost faces now usually gets draped onto - if you have overlapping faces in the groups the drape should not now 'punch through' onto lower faces, unless the faces are with ~5mm of each other vertically - still it's best to have single-skin meshes to super-drape...

The splat/error reported by Dave_R is now avoided by recoding... BUT it doesn't fix his mesh itself, which had two quad-faces that appeared coplanar but caused splats because when the mesh was intersecting with other entities they made the result unstable - after erasing those two faces they would no reface with 'find_faces', but adding a diagonal fixes the issue as they two triangles are just on the cusp of the difference between a viable quad and two triangular faces that are not coplanar. I await for Dave to re-break this version

Hi TIG,

I've tried it with no success. I do not know if that's my fault. See Picture below.

I can't get any error messages, BUT I don't get a good result either!
BUT if I explode each group in turn and immediately regroup the highlighted entities... and then use SuperDrape with them it works just fine
I suspect that there's some duplicate/tiny faces or similar 'errors' is the group[s] that cause issues - but the explode+regroup fixes them...
I'll see what I can come up with - in the meanwhile use the explode+regroup trick and it seems fine again...

Thanks for the tip. Your plugin has a great potential as always.

VERY COOL! Thanks TIG this will come in extremely handy.

numbthumb · 5 Oct 2011, 16:49

Where would we be without all this stuff... thanks!

Dave R · 5 Oct 2011, 17:15

Thanks TIG.

So the splats occurred because those two quad faces barely qualified as quads? It sounds like SU let Fredo's skinning tool make quad faces but wouldn't let your tool work. Sounds like a double standard to me.

I'll give it a try as soon as I can and let you know how it goes.

charly2008 · 5 Oct 2011, 17:20

As always with new tools, I need to experiment with.

TIG · 5 Oct 2011, 18:23

Glad you're enjoying it

One of the issues [but not all] about your original problem was that you applied the material to the draped group and not the faces with in it...
I plan to spot this in the next version and ask what you want to do...
Also your sphere had a convoluted transformation - removed after the explode+regroup... I looking at ways of trapping/sorting this too...

Here's v1.2 http://forums.sketchucation.com/viewtopic.php?p=358314#p358314

Following Charly's feedback it now spots if you have a material applied to the draped group and that there are some faces inside the group without a material [they will appear to have the group's material, even when they are actually in the default-material] - you can then choose Yes|No to use that group.material for any draped faces that would otherwise have the default-material.
The intersecting is even more robust.
All underlying faces inside the same group should now be unaffected by the draping [i.e. any faces below the draped-on topmost faces].
Draped faces that partially overlap the edges of the draped-on group's faces are now neatly trimmed to them.
Groups with convoluted transformations [rotated in 3d, scaled etc] should no longer cause issues with the draping.

Feedback please...
