Just curious, but how many of the processes are multithreaded; like switching from vertex color mesh to standard solid mesh takes a very long time on 40mil poly meshes, and I notice it is using just 25% CPU... are there plans to make Photoscan more multi-threaded?
I made a scan of a large section of a wall, and when I generated the mesh, it said High wanted about 34mil polys I think.. so I set it to custom and went to 70. Looked soft, so I chunked it out an redid the dense cloud (at high) and mesh at custom of 40 mil (this time high said 24mil). not any sharper in that area, but my question is.. did I need to redo the dense cloud? What are the steps to get more resolution in details areas you break off to their own chunks? Did I do it correctly? Should i have re-aligned and maybe gotten a better tie-point value or something? Is there any overhead lost by not doing this, or by not deleting the cameras that don't contribute to this new section? The reason I know this is not a limitation of the source images is because the dense point cloud looks better than the vert-colored mesh... There is still far more detail there.
Possible bug:
Finally (for now), when generating large meshes like this, my machine with ~260GB of memory gets taxed pretty heavily, as expected, but I am noticing visual issues.. where some of my mesh is missing in the solid view immediately after the mesh generation finished, until I turn the colored mesh on.. You can see this in the two screenshots I am attaching. I have seen this numerous times before, and the mesh is indeed missing for that lower section until I switch. Trying to switch back to solid mesh, ALWAYS freezes at 25% CPU maxed for a very long time.
I can go back and forth between dense point cloud and vertex colored mesh in less than a few seconds... Sounds backwards? Is there no shading and specular or something with the colored mesh? All I know is that it pegs 6gigs of ram (went from 100 to generate to 20 after, and trying to go to solid dumps the ram and jumps to 6 and just sits at 25% cpu.. I have not been able to get a solid mesh view at these resolutions easily. Curious if it's the memory on the GPU limiting the system? I have two MSI 970GTXs and one Quadro K4000 (which is set to be my display card in nvidia settings). Any help in figuring this out would be appreciated.
Thanks!
