I’ve recently started a substantial effort to (attempt to) bring ODM to Windows. Natively (no docker, no WSL, no nothing). This is my third attempt at doing so across the years. I have good faith that third time is a charm and that I will succeed.
I’ve managed to build (and run) the two main dependencies (OpenSfM and mvs-texturing):
Next up, VTK, PCL, dem2mesh, dem2points, PDAL, entwine and untwine, OpenMVS and the rest to follow.
I will keep updates on this thread, to share the progress.
Yoooooooooooooooooo.
That’s amazing.
I believe a good number of those dependencies should be built or buildable already via the OSGeo4W-NG repository, which is 64-bit native these days.
Is that a tenable thing to loop in and save you headaches, or do we carry enough patches that it wouldn’t help?
We have a lot of patches 
I’m hoping the end result will be able to stand on its own.
Removed VTK altogether: Removed VTK, odm_cleanmesh module by pierotofy · Pull Request #1275 · OpenDroneMap/ODM · GitHub
I remember that being a huge pain to get sorted when I was YOLO-attempting an upgrade path to 20.04 before we hired Dan to do it right 
Any dropped heavy dependency is great news!
Might be time to revisit making my Alpine-based LiveODM…
Removed dependency on zstd.
dem2mesh, dem2points, poissonrecon all build too.
hexer, laszip 
Untwine:
Entwine has some deep path handling issues to work on Windows. We’ll just use Untwine.
And OpenMVS of course (had no doubts on this one):
This completes the SuperBuild dependencies.
Are all these dependency drops and other changes applicable for the Linux/Mac/etc builds as well, or is the native Windows port a more separate/hard fork that is a special case that needs to be maintained differently?
No forks, everything will stay under the same branch / codebase.
To quote another Italian named Cristiano when I informed him of this effort: “Grande Piero.”
First native pipeline run completed from end-to-end. 
Orthophoto, textured models look great.
Elevation models exhibit some strange artifacts and incorrect elevation values.
Troubleshooting continues.
