General / Re: Build texture for edited and re-imported mesh
« on: June 30, 2021, 10:17:27 AM »
i haven't used Blender specifically for this but i can't see it being any different to other apps.  you just need to make sure you don't move, scale or rotate the model in any way in Blender.

also make sure the model isn't rotated or scaled on import into Blender, or when exporting.

use the 1,3, and 7 (5 to toggle ortho/perspective) keys in MS to see the model in front, side and top view respectively, and you should see the same model rotation in the respective Blender views on import

those of you that have this CPU, what are your temps like at idle and full load?

General / Re: build mesh from depth maps vs dense cloud

thanks for the suggestion James.  i went through the process but using polygon size as a filter doesn't work as the parts i need to delete don't necessarily have larger polys.

so AFAICT it's either mesh from Depth Maps which is better defined mesh but unwanted extrapolated polys or mesh from dense cloud which will give a better cropped mesh, though not as defined.

is cloud processing from MS Standard still under consideration?

thanks but i already tried that and there's just no consistency in the parts that get removed

pity i can't get this to work because apart from the extrapolated parts the generated mesh is generally better defined and it's a much quicker process, but there's simply too much made up stuff

the bit i'm struggling to understand is that Alexey says the extrapolated parts can be removed with the confidence filter for the depth maps but i only see confidence filtering for the sparse cloud, dense cloud and mesh, not for depth maps

am i missing something simple here?

I think that the extrapolated parts could be filtered out and removed by the confidence filter for the depth maps based mesh generation approach.
forgive me for insisting Alexey but you hinted that it could be possible to filter the extrapolated geometry (which would save me so much time /and/ improve the models) but have left me no clues as to how to achieve this

i have Metashape Standard - is it possible to filter out the extrapolated parts without building the dense cloud?

anyone?

thanks

AFAICT you can only filter by confidence the Dense Cloud right?  in which case the speed advantage of generating the mesh without a dense cloud is lost
here's a screenshot of where i am now.  i can view the model confidence but not able to select by confidence like i can with the dense cloud

i found the Model COnfidence view but i still can't find how to filter the Depth Maps.

how would i go about filtering the extrapolated parts out?

currently looking to build a different mesh and have the same problem.

i built a mesh from depth maps (settings were both on High) and the resulting mesh is 25 million polys.

any way to know beforehand what the approx poly count will be, similar to how it works when building from dense cloud?

thanks Alexey - please see attached.

with the dense reconstruction i have always used Default interpolation .

with the depth maps i tried Default and Disabled but the result is the same.

thanks for confirming

thanks Alexey.

that's what i've been doing and i'm happy with the results, but i always wonder because the manual states to avoid those lenses.

is there any disadvantage to using FE lenses this way vs regular lenses?

any views on this?

those of you building meshes from depth maps only, are you getting these extrapolations?

seems to be a lot of conflicting information on this with some saying it's a big no no, and others saying it's a must have.

is there an official view on this?

i'll be scanning a garden this week using a painters pole to get some height.  Should I use IS?
