General / Typical FBX export speed?

« on: July 16, 2016, 06:54:11 PM »

I realize this is one of those "how long is a piece of string" questions, but I have to wonder if something is wrong.  I've let FBX exports on ~15m face meshes with vertex normals go for hours and seen 0% progress.  OBJ takes a few seconds.

Dual quadcore, 256gb ram, 3x gpus.  Latest Photoscan as of this writing.

I am merely trying to get a mesh with the vertex colors out of photoscan to see if they are even usable for me.

Oh, ok, great.  Where is that log file stored on disk?

Or google remote desktop.. remote desktop in windows kills the openCL calculations on the cards.. teamviewer and google remote desktop preserve this.  Hope it helps.

1.2.4 build 2399 x64

Unfortunately the log was overwritten with new operations.. Is there a backup or something I might be able to grab?

Thanks Alexey!

I will report back shortly with all of those details.  I believe this pass took like 4 hours.  Which for 40 million faces doesn't sound insane, but.. I rarely ever use the vertex shaded mode, and for brute force processing speed, I'd like the option to turn it off is all, unless, of course, it's used by other processes. 

I'll get those details to you soon.  Thanks, Alexey.

I should also mention, that I realize this is for the shaded model view, but I rarely use this, and since it seems to take a lengthy processing step, can it be avoided?

General / Re: Highest Scan Quality - Photo Res vs Cloud Density vs Model Quality

IMHO...

More angles is always the way to go.  What is the output?  Are you producing human scans?  Environments?  What for?  Games?  Features?  VR?  etc etc..

A lot of these questions determine the avenue you go to be honest.  Body scanning rigs are soooo vastly different than my rig for capturing assets and elements.

My machine is a dual quad core, 256gigs of ram, 2x nvidia 970gtx, 1x quadro k4000.  It is not the fastest rig, but it pushes some serious data through.  I've run out of ram twice on stupid high scans that I tested the rig with (another better-tuned scan with still very high settings ran for 24 days straight and didn't crash).  The software is very very solid IMHO if you do things properly.  For instance.. "ultra high" is not a test... it's completely useless for large data sets.  It might be amazing for close-up skin scans with a low photo count, but for what I am doing, it's overkill that is never seen.

Look into renting the amazon cloud computers for ~ $3 an hour.  Their core counts are just disgusting.. it's the cheapest way to go IMHO, and you can network process with a few.  If you need that power.  I am looking into setting up the base scans, saving the files, and kicking it off to the amazon farm to process.  That way I can keep producing without locking my machine up.  Just a tip. 

Best of luck.

Curious what this step is actually doing (under the hood), why it's sooo slow, and if it's even necessary for my needs.  Just wondering about the process itself, and if there's a way to eliminate it or make it faster.

Thanks in advance!

jazvec.. I am really curious to see where this ends up... I had no idea there was the possibility of this when using certain applications.

DEFINITELY!

I am using two 970 GTXs and my old quadro k4000.. while the quadro kicks ass with CUDA, it is actually half as fast as the 970's for this sort of openCL calculation.  All together though, the system hauls ass.  Add everything you can.  Alexey and the team did an awesome job making Photoscan utilize every possible ounce of power IMHO.  Hope it helps!

Feature Requests / Re: Bracketed exposures and HDR

« on: July 03, 2016, 04:18:13 AM »

I'm thinking... Wouldn't using one of those exposures to makes the scan be ideal, then using the HDR to apply the texture?  Does Photoscan do a better job to build geo using HDR images?  I was always under the impression that it preferred raw images without any processing.  Curious.

Very many VFX firms use Deadline.  This would be a smart move IMHO.

Yeah I got that vibe, thanks for the link though.  Pretty clear that they have been acquired by a larger entity with many rules lol..

But.. results-wise.. I would love to heard Wishgranter's findings if he ever got that data set.

I am very impressed with the results and documentation in that linked post, but did I miss where he posted the settings?  Just saying ultra high or high doesn't really capture all of the rest.. but still.. I care less about the time and more about the accuracy, and in many of those scans it seems the other software did a better job.. but those polycounts are too low for my liking.. the shark text it got on the carpe diem was night and day different.. I'd love to test that data set with my PSscan and see if I can;t achieve the same results with setttings I tweak.. regardless, Agisoft should be looking into these disparities...

EDIT: oh it seems Wishgranter got the data set.. did he ever post any results? He's a very active Photoscan user...

General / Re: [RESOLVED] PS just sees 1 of 2 GPU's

« on: May 10, 2016, 08:04:30 PM »

I had this happen too.  Chrome remote desktop does not disable OpenCL; neither does teamviewer from what I hear.

And you don't need the SLI bridge.  I am running two 970GTXs and one quadro K4000 and the GTXs are double the speed.  OpenCL and CUDA are not the same. 

Hope this helps.
