Ok.. so is this caused by bounding box orientation?

I am still confused by bounding box orientation as a whole because I see red as the "top" (which could mean Z or Y depending on your preferred app of choice..), but when I import into max as OBJ as the typical default from Maya or Zbrush with the Y conversion, the geo is facing downward...  I am used to max being weird.. Maya and Zbrush, etc.. being the "norm" and using the Y-up conversion as a standard.  so... how should I set up my bounding box in photoscan to get it into max with my "typical" defaults, so that front is facing front, top is top, etc...?

Also.. what is "front" in the bounding box?

When I hit 1 on the keyboard, I see front.. the bounding box should.. reflect that...?  No?

Is this at all configurable like z-remesher?  Control curves?  Anything?

I see no reason why you can't export mesh.. UV and quad however you want, re-import, and build texture with "keep UV" .. or am I missing something in that software?  Didn't see much in that link.  :)

While making selections of faces or points, it would be useful to be able to orbit from the averaged center of the selection.  This helps refine selections quicker IMHO

Rad.. Thanks for the uber fast support Alexey.  Much appreciated.  Would be nice if there was an orbit viewport option to always keep bounding box center as the center?  Does that make sense?  In max you get three orbit modes, for sub-object orbit, or parent orbit or center viewport orbit.. it seems like photoscan is center viewport always, which makes sense, but it makes orbiting around complex selections nearly impossible with heavy files.

Just an idea.  In either case, thanks for the quick fix/tip!

This should have an option to adjust how sensitive this is.  Odd because it's the opposite in most other software I use.. perspective has a clipping issue where ortho sees infinite.

Any idea how to fix this?

Adaptive ortho brought into uvlayout.  all white is flipped.  Normals appear correct in viewport.

Adaptive orthophoto/mosaic works better in this regard, but using general/mosaic with the same resolution map size gives huge gaps between the millions of tiny Uv islands.  There should be a tolerance to dial in for the amount of stretching before an island is broken off, the distance between islands when packed, and the amount of pixel bleed.

These are necessary for use in other softwares.

Also.. I just exported a brick wall scan and the UVs were flipped randomly.  They should all be facing the same direction.  This significantly affects any bump/normal mapping calculations if one were to do that.

This exists... Or am I misunderstanding?

Isn't this the same thing as photoshop?  I mean, it isn't magnetic lasso.. that could be cool.  Or are you referring to photo pane?  You must be referring to photo pane.  That is a good point.. because the lasso icon there is intelligent scissors, lol.

Never quite paid attention to that before.

There are many missing features for selecting and deleting, like crop to bounding box

We use a creaform laser scanner at work.. even with that $30k+ scanner and software.. you STILL need to reduce glare with a chalk spray.. reflections will always mess up every single thing that you try to scan.  Turntables are great, but they (usually) vary the light across the object, unless, of course, your controlled lights are attached to the turntable.

I used to spray the bottles I had to model for Specalized Bicycle with grey matte paint, and even then, I had to attach random markers to the object for alignment.  Turntables are not what this software and technology was made for, and IMHO every successful scan is merely an exercise in beating it into submission in order to work.  ;p

Some have better luck.  I have limited patience and time.  I can grab the handiscan and get a usable object in ten minutes if I spray it or try and mess with photoscan settings and masking for an hour then wait for processing. 

Alternatively, I could try to scan a 150' section of an alleyway with the handiscan here in Detroit, but.. I'd get mugged, the scan would take days and more ram than any computer could handle, and photoscan did it in less than 40 hours total. so.. they have their merits.

Just something to consider... IMHO you're using a screwdriver to hammer in a nail so the best results you get are gonna take much effort on your part.

Luckily Agisoft has added in a ton of features to help.  Utilize them.  I will say though.. you need VERY diffuse lighting and no spec hits.  Your photos are the first step and 99% of the variable in this process.  As flat and consistent as you can get them, the better.

Anyhoo.. hope it helps somewhat. 

Also.. on this project, everytime I open the file, or the viewport resets, my geometry and bounding box are off to one side.. does the "fitting" of the viewport always look at the sparse cloud or all cameras?  When I decide to part out a scene to smaller chunks, I delete dense cloud points and reduce the size of the bounding box, but I hardly ever worry about the sparse cloud.  Is that affecting me negatively in any way?

Just curious what the best steps should after doing an alignment of a larger area, then deciding to detail out parts and break off chunks to separate files for further refinement should be.  Once I have a dense cloud of the whole area, say, for instance, 150' of an alleyway wall.. and I choose a 20' section to be my next asset, I delete all of the dense cloud points I don't want, shrink down my bounding box and then.. should I re-do the dense point cloud generation?  Should i delete the cameras that absolutely don't contribute?  Or can I go straight to making the mesh using dense cloud points? 

What is the best method here for quality, and also alternatively, speed?

Is the dense cloud the best it will ever get upon generation at any size, or is it's resolution determined/limited by the bounding box in some regards?

Thanks in advance.

Yeah I am just missing that precision.  In max, I can use spinners to rotate with precision. 

Hey Alexey,

It's more a problem that in an ortho view I can't ever seem to get a straight rotation of the box.. like I don't have enough precision on the rotation so it's always just a bit off.  Also.. no good viewport alignment options to make sure things are straight.  I am doing a bunch of brick walls, etc, so I have to move the point cloud to the bottom edge of the viewport to rotate and use that as a "level" line.. it's just not the best method IMO.

I feel that this whole system could use vast improvements. 

And while I own the pro version, I have not learned enough python yet to be able to do any of this.  I wish the community here shared more of their python scripts to be honest.  We need a "" type community for photoscan.  ;p

perhaps a polygon-lasso?  more of a click-based, not click and hold?  I would LOVE this.

You can draw polygons now, but yeah, I really wish the lasso tool had a polygon mode.. especially when using my machine via remote on a shaky wifi connection.. :/ 

clicking and holding to make a lasso selection for 2 minutes because you aren't sure if the connection dropped is no fun.  ;p
