[Plugin] Manifold v2.2

driven

Hi all

can anyone confirm if they can see TIGtoolbar, while running manifold1.3, this drawing really slow compared to 1.2 and I just noticed I don't have the TIG-RRby icons in the toolbar which have never vanished before....

johnEDIT: TOOLbar sorted didn't update TIG folder in my rush to try 1.3, so that shouldn't effect performance, must be something else

Check your files are in the same folders as shown in the original zip ?
It might be a bit slower running because the new algorithms ?
Try it one something simpler first ??

I was editing while you were writing, and yes Ill go back to the slow start procedure, It was simply tea time and I though "this model works with 1,2, I'll just quickly re-run it, etc.."

driven

from my understanding...

I've got the reference somewhere if you want me dig it out, this is two two manifold objects sharing an edge...

basic are quicker, easy start...

I did. I didn't have any issue with light leaks...but I used a higher poly version than most.

Light leaks are one issue. But more problematic could be if you like to produce caustics or SSS (not single face). Broken mesh might not be that obvious like it's with light leak, but result will be wrong... you just wonder why you cannot get proper caustics.

TIG,
This would pass

probably showing the obvious

TIG. The internal triangle was gone after this pass. I'll have another shot at the bigger file now and see it in the morning.

TIG, found the dialog boxes,
I was getting a system error Plugins/BZ_Dir_13/bezierspline_main.rb:2098: warning: Object#id will be deprecated; use Object#object_id whenever I used your tool after using any of Fredo's tools so I fixed his script (at least I did what my system suggested) and have been working my way through some simple test to see what slows or breaks, only just got back to curves (no beziers yet), and I thought I'd post the successes, to date.
I wasn't getting this far before my fix
this was just to show, how drawing it right in the first place would save all these fails

I also found this and tried to get an evaluation download, but it's for PC's but may be of interest, it also adds to the list of NOT 3D PRINTING USES for Manifold Objects and flies in the face of my earlier comment on GEarth models.

Virtualwind's advanced 3D wind flow simulation and visualization. Within SketchUp, Virtualwind's Validation Tools identify and visually highlight non-watertight geometries and problematic textures in the model. Non-watertight geometries are typically surfaces on building models that do not have contiguous adjoining edges (i.e., models that do not have a "wetted surface", a "water-tight" exterior). Problematic textures are usually faces with back-only textures or back texture different from front. The Virtualwind toolbar also provides Correction Tools to correct these issues. For non-watertight geometries, there are toolbar icons to remove zero-faced edges and to sew edges together, thereby helping to create a water-tight model. There are also toolbar icons to correct problematic textures. These model corrections are important to provide more accurate wind flow simulations.
anyone want to try it out and report back

Sure...PM me a few sample models

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
http://forums.sketchucation.com/viewtopic.php?p=218691#p218691

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 !!!

TIG, no dialogs and I get this that I haven't had before,

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???
