It appears quite a few users would like to purchase this proposed alternative version, with a relative consensus on features...Siggraph is coming up soon, good time for an announcement?  ;-)

Hmmm, hard to tell from the brief description, but it could be a combo of both perhaps. Seems to be describing something a bit more synthetic, though.

It looks like there is a new free FBX format viewer from Autodesk for iOS and Android...not sure how hard you can push it.

Ooof, yeah, 100 megapixels doesn't help much when they all look the same. =(

Those shiny car panels are going to be tough. You could try to accentuate any available contrast and details in those panels in the hope of bringing out more distinct features that the software can grab on to...but it's probably going to be very difficult.

Feature Requests / Re: Middle mouse drag for photo navigation

Try shift+drag, I think that should allow you to pan around while zoomed in, and will work even in mid-shape drawing mode.

You could try using the Lightroom or Adobe Camera Raw highlight and shadow recovery tools, they sometimes can help bring details out in darker and brighter areas. If you have RAW images to start with, you will probably have better luck with that. But it still might prove very difficult to get a decent solve in Photoscan.

Good luck! -C

+1 absolutely

I think a lot of us are trying to 'make do' with the standard edition, but would happily pay a reasonable premium for these extra features that would bridge the gap between the Pro version. Marcel's description of the three key features and example pricing seem right on the mark.

Thanks, -Chad

Bug Reports / UI super slow when viewing detailed shaded masks

« on: May 06, 2014, 10:46:02 AM »

Ok, maybe not exactly a bug, but this seemed like the best place to ask about an issue.

In the MacOS version, if I import a set of masks that have a some noisy areas, the UI gets super slow when displaying those masks and trying to edit them further. I've been creating the masks through some keyer tools in Nuke, and they aren't always super clean extractions, resulting in visual noise in the form of lots of little white pixels scattered about it some areas.

Once I clean up the noise a bit, the UI gets much faster and responsive. So the basic idea of a lot of highly detailed outlines in the overlay is very bad news for interactivity.

Is there a way that Photoscan is drawing the overlay for the mask outlines in the UI that has some issues when trying to draw a LOT of them? I can push around millions of polygons without a problem, but a bunch of 2D outlines is a major slowdown.

It reminds me of an old issue we had on SGI machines, push a bit too much into the UI overlay graphics on the machine, and it would grind to a crawl...which otherwise was quite responsive for its time.

Anyway, just wondering if there was a way to fix that issue, because it really makes it hard to use the software in this case.

thanks! -Chad

You also might try looking at Meshmixer for creating shells:

General / Crowdsourcing Masks...

Well this is a novel idea...why make all of those tedious image masks all by yourself? Why not ask the public for help?

General / Re: Batch processing?

« on: April 08, 2014, 12:58:49 AM »

Hi Alexey, so speaking of batch processing...

There are times when the region box that PS sets after the Align Photos stage is set incorrectly, like at an odd angle that clips off a critical part of the intended object. So when batch processing, all of the stages after Align Photos have to be discarded because I have to re-align the region box and kick off the rest of the batch again.

It would be great to have an optional setting where PS was less aggressive with setting the active region and expand it out a bit further, even if it comes at the expense of processing time. Extra processing time while unattended is better than lost processing time due to a clipped region. Once again, it would just be an option, so as not to change its normal behavior which is accurate in many cases.

thanks! -Chad

Face and Body Scanning / Re: Improved masking options for human scanning

« on: April 03, 2014, 10:07:25 PM »

Using some compositing-oriented tools can really help speed up the process; and give you better results. Something like Nuke, After Effects, etc. Even some automated pipelines in Photoshop could help, although not quite as ideal for dealing with variances between images.

You can extract mattes from clean bg's and also from any type of color; and combine various partial matte extractions to build up one perfect matte. Plus they have options to 'grow' or 'shrink' your matte if you need to trim or expand the matte. Those programs also have some nice color suppression tools, for when are finding something shot on blue or green screen is casting too much of that screen color back onto your subject.

They can handle roto tasks faster than Photoscan usually, too. (although Photoscan's magic lasso tool is pretty handy)

I'd love to see more of those tools inside Photoscan, but they are some not so small feature requests.

Cheers, -C
