Calculating vertex colors... Why?
« on: July 13, 2016, 03:40:54 AM »
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!

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?

Hello MeHoo,

Which version of PhotoScan you are using? And can you also provide full processing log related to the mesh generation operation?

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.

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!

Hello MeHoo,

If you have the log enabled in the Preferences, the new information is just appended to the end of file.

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