General / Experimental Mesh Generation Stuck on "Estimating Best Cut..."

« on: August 31, 2018, 08:14:58 PM »

I've been using the experimental mesh generation method to create a mesh after getting repeated index overflow issues with the traditional method, but I'm currently stuck at "Extimating Best Cut..." and it's been there about 18 hours.

Does anyone know if this part of the process happens to be single threaded and CPU based?  Nothing is being used but about half my ram and 4% of my CPU.

General / Best Way to Add More Points to Dense Cloud?

« on: March 27, 2018, 06:35:15 AM »

I'm trying to get a denser point cloud to work with and I'm wondering how to best go about it.  It's not that i'm trying to get more detail, just that I need more actual points being placed before exporting the point cloud to other software.

Does anyone know how I could do this?  Best way I could think of is just to increase resolution in the source images but that seems wasteful in terms of processing.  Is there anything equal to "Refine Mesh" for dense clouds?  Maybe something like "extrapolate more points from neighbors"?

General / Windows OS Laggy While Building Clouds (Regardless Of Free Resources)

« on: July 04, 2017, 09:11:52 AM »

I've been building some dense clouds with Photoscan Standard and noticed how completely unresponsive Windows is at times, often with the mouse cursor slowing down to like 1 movement per second.  Web videos stop playing, apps freeze and all that other stuff that comes along with process intensive programs...

Not all of my resources are being used though.

I have a video card dedicated to running windows (my display card is a GTX 1060 and I have two 1080s used for rendering and processing).  There are a number of GPU rendering apps that I use in this way and because my display 1060 isn't used for rendering there's nothing slowing down the video processing for Windows.  Everything stays running just the same when I render as when I'm not.

The CPU for Photoscan has it's affinity set to 4 of my 8 cores so my processor load for the cloud building is never above 50%.  I've also set the process priority to below normal without any changes.  There should be enough free CPU overhead that Windows shouldn't be lagging like it is.

Memory wise I have 64GB in this PC and Photoscan is currently only using 5GB, so it's not a memory issue at all.

Does anyone know what might be causing the lag issues?  Currently Photoscan is really the only program I use that does this sort of thing.  I'm very used to multitasking without any problem, sometimes even rendering with CPU based software like Vue while rendering with GPU software like Octane at the same time.  Based on my system performance I really shouldn't be kept from at least watching Youtube while clouds are built.

General / Method For Masking Out Sharp Pixels?

« on: November 13, 2016, 07:55:23 PM »

I'm wondering if anyone knows of a way to create a mask based on the sharpness of pixels in photos used for generation, either within Photoscan or through 3rd party applications.  With my scans even at the highest aperture (f22+) I'm having some trouble with depth of field.  Not so much with the 3D model generation but with the texture creation.  Regardless of there being sharp "in focus" information for every part of the model Photoscan tends to also use the blurry "out of focus" parts when putting the textures together.  If there was some way I could tell Photoscan not to use those portions it would be awesome (as far as I know masks can't be used for textures so I'm guess it would be done with image processing).

I came across this thread with the same issues and they suggested a tool used to detect image sharpness, but I'm hoping for a Photoshop method etc that will detect a feature as sharp and map it as white while blurry portions get set to black or transparent.
