Low CPU usage?

    are you at the very end? it seems there is some post processing at the end that's only single thread.

    or have you run out of ram, and waiting to feed it more data?

    90% of the time it should be running at 100%. for mesh reconstruction.

    Hello everyone. Same CPU usage problem mesh reconstruction . how to fix it?

    Hi jacobcarl2016
    Not every step can be multi-core ( out of core ), so some steps are just single core.. But in most cases all cores are used...

    Make some screenshots with the CONsole view so that I can say what can be done..

    I was seeing CPU usage bouncing around between 15-30%, but looking at the console it looks like it might have been during the "calculating depth maps" step which I suppose is not that CPU intensive then?

    On later stages the CPU bumps up to 100%

    At the end of reconstruction (60-70%) it dropped again but that was normal right?.

    I noticed that reconstructing in normal has a "Force single part mode" setting but not when reconstructing in high detail. This in turn gave me a mesh with 110 parts and...aheum...350M Tris...thus taking a really long time to render. I imagine this might have had a negative impact on the performance of the reconstruction process. Or it was possibly running a low CPU intensive step for a long time when I noticed it.

    I'm very impressed that I was able to finish that reconstruction process however without crashing, even though it took 6-8h or so. :P

    So yeah...I'll probably be using the normal setting when reconstructing mesh from now on. I find it easier to control than the high setting, or is it better to use high and bump the detail decimation factor?

    Hi daniels_mail
    Yes, this is OK for all the steps.. as I have mentioned earlier, not every step can use all CPU cores...

    Personally, I never use HIGH at first, every time I go with NORMAL and after having inspected the reconstruction, when everything is fine and so on, then I run the HIGH, as it is 4x more time-consuming than the NORMAL mode....

    Ok, how do you go about defining the resolution of your final mesh when reconstructing in high? It splits the mesh into a bunch of different parts but I can't define how many afaik? I can limit the max vert count per part I suppose but that won't tell me how dense of a mesh I end up with without knowing the amount of parts.

    I do like the results I'm getting from just a normal reconstruction however, not sure how much improvement I would see from running in high at same density.
