Is there any way to display a mesh total surface in square meters (or square units) ?
->I would like to find a more reliable and reproductible way to calculate my target triangle count when I simplify my meshes : in the same way we can define a texture resolution (in texel size in units/meters), it would be great to have the same for geometry (in triangle/egde average surface/len).
Hi Jonathan,
do you mean the surface of the average triangle?
That could be approximated by using the Minimal Distance Between Two Vertices option in the reconstruction settings.
And the Minimal Egde Length is a part of the Simplify tool. That is waht you are looking for, not? Or is it specifically the average edge length you want to define?
No actually I mean the total surface of geometry (sum of all triangles surface). What I am trying to do is get some metrics to compute my target triangle count when I simplify. I found how to do that in MeshLab, it works very well and gives me the total surface, which I can then turn to a target triangle count when I know the quality I want to reach (which is my average triangle surface, let’s say for example 0.01 m2 or 0.005 m2…).
I just wanted to avoid the extra step of exporting to ML.
Ah, I thought you wanted to control the area the model will have AFTER simplification.
But what you want is the info of how large the area is so that you can adjust your texture accordingly?
That should be simple enough - I think they added the average edge length also after a request only…
Is there a solution for this in practice?
Hi aslanbey8325,
There are feature in new release for area and volume measurements: https://www.youtube.com/watch?v=SLGImZYy4aw&t=430s. It starts at 18:03 in that video. But you have to have created ortho.
