After having small tests with wedodm, I noticed that webod has difficulties with straight edges when default settings is used.
Hopefully the images will pinpoint my concern. The first image is created with webodm
This image is created with commercial mapping program (free version).
Are there any soltutions to improve the results?

This is a series of changes that replace `odm_dsm2points` and the call to `Poiss… onRecon`, which is the current approach to 2.5D meshing, with a new program, `odm_dsm2mesh`, which uses a gridded + quadratic simplification tiled approach to meshing.
The approach creates higher fidelity meshes from a DSM, keeps the memory usage linear via tile splitting (the mesh is split into tiles before triangulation and each tile is processed independently, then merged at the end), creates good sized triangles (important for texturing) and is reasonably fast.
I will post screenshots of orthophotos for comparison to the current method in the next several days, but I thought I'd ask for early feedback and some help with testing.
Given the novelty of the method, I was also thinking of publishing the `odm_dsm2mesh` program in a separate repository and pull it into the ODM build process. Let me know your thoughts about that. :smile:

Probably yes. I just got it working yesterday
BTW- How can I check the versions?
Running docker run --rm --entrypoint cat opendronemap/opendronemap /code/VERSION should give you the OpenDroneMap version.
The latest is 0.4.1.

The command updated the code and now the quality for that is better. Thanks.

are you running the latest version of WebODM/ODM? Two days ago we’ve made some updates to improve exactly what you are describing. If not, I suggest updating and trying to reprocess the dataset.
