[Plugin] Manifold v2.2

d12dozr

anyone want to try it out and report back

john

Sure...PM me a few sample models

TIG

The groups that it creates, is it suppose to be offset from the original group?

Yes - so you can see what it's done more easily.
The errors overlay so you can see in xray mode.
Then you can grab that by the text handle and move it again to see it more clearly - if you edit it and select its geometry by double click then any errors shown by clines [different stipples for different failures] for 'pretzelled' edges etc will show clearly again...

Here's v1.4

It has some improved algorithms for inner flap removal...

Still fails on some 'pretzelled' shapes...

Have you got the program?, I put a link at CornerBar, and really the test I'm suggesting you/and anyone else to do is just checking some of your own or 3D WareHouse stuff that looks watertight, and see how the plug behaves, cope, etc.. , then run the same model with Manifold1.4 (and rising) to compare results. It can then define some targets/parameters for this super-duper one TIG is creating. which is coming along very well indeed.

thanks for putting your head above the parapet..

MORE TESTERS REQUIRED....

I just installed it...164 MB! I'll run some tests but if you have some models you know you are are having problems with, send them to me...easier than me starting over from scratch

the 'pretzel' is posted up the top, TIG's name on front, that gives trouble on careful examination, small triangles round the back, I think... I've got harder tests but one step at a time, I got ahead of myself....

TIG......THIS IS SO FAST... I didn't have time to start the stopwatch on the boxes.....CHEERS

anyhow, more testing...

What does the word "manifold" mean in this context? I gather "water-tight", but is it more than that?

Yes , and tons of info at wikipedia, but the way I described to my six year old if the computer trying to find the walls of a room from the inside and the window is open it will precede to circumnavigate the earth until it gets back to where it started and then panic... she believed me...

Manifold means 'many' or 'of many parts' - it's also a type of thin typing paper !

But in the sense of a 3D mesh it means 'whole', 'complete', 'imperforate', 'without holes, imperfections, complexities or sub-elements'... from the Mathematical term "Manifold: a Topological surface or space that is connected and locally Euclidean"...

Ironically its 'antonym' is 'simple or single', which is exactly what we are trying to achieve with the processed mesh !!!

I haven't changed that ? It's trying to map textures back onto triangulated faces properly ??? I'll investigate...
Avoid textured faces for now...

TIG,

I have had it before, I just went back through the logs and buried in there is the same report, at least for 1.3, 1.4

driven

A re-start found the dialogs, so 1.3 would not pass this (which is correct) due to more then 2 faces per edge, also reversed faces made it through...

passed???

driven

Here's a semi complex one that sort of worked with 1.2, but on 1.3 it would only hang....

I might get this one printed in stainless, should only cost $100, and I can't think how else to make it.

I'm about to re-test it on my Mac and a PC comparison would show up if some of the problems are me or not...

If it fails first try, manually orient the reversed faces, then remove the internal disc on the bottom run and try again.

it 'should' remove the internal overlap on the bottom 2/3 twists (1.2 left these intact)

it might still make a hash of the end, Fredo's bend tool can be unkind to meshes.
I been running it without manual repairs

HI,TIG,is there have some differece between trigulaer face .rb and Manifold v1.4?

If the read the notes in the first post... 'manifold' does triangulate faces at the end, BUT it does so much more - it tidies the shapes to remove faceless edges, remove flaps, remove disconnected geometry, heal holes and very small faces, orient faces and then triangulates, and finally 'reports' on what it's done.

It is an attempt to automate the making of a 'manifold' surfaced mesh that will work properly when it's exported for use in a 3D printer, and some other 3D apps...

It's still under development...

Cheers TIG,
I was just logging in to say, I've set up one of my Macs, with a fresh instal and only a few basic rubies that I've triple checked are clean. Just to test Manifold. That way any log errors on my system console should be easily spotted, and you posted this, so excellent timing. I'll keep you informed. john

Can you PM that file so I can test it too...
Don't bother - I made one like it and I see the problem
