How to get specific vertex count

[m3vbih]

Hi,

Pardon my newbie question but I can't figure out how to get specific vertex count when do decimation.
I display my models on website and I must keep my models below 1.000.000 vertexes. When was using other photogrammetry apps I would target around 700.000 vertex and it worked ok.

In 3df I generate mesh model then choose to decimate and choose target 600.000
But when I texture decimated model (I apply texture after decimation) and when i export that model in GBL format I see that exported model has 1.190.000 vertex.

So how to tell 3df not to go above 700.000?

Hi m3vbih -

It sounds to me like the issue is as follows:

- You make a (non-textured) mesh, you decimate this mesh to 600,000v

- You then make a NEW (textured) mesh, so it doesn't really matter that you decimated the other one, a new mesh is created, with it's own properties.

----------------------

Solution: Restrict the textured mesh max vertices in the advanced settings of the textured mesh generation wizard (ref image attached).

Tnx, sound as this was problem.
Will try this when I get home.

I tried what you suggested but still I don't get exact number. Or maybe I do but something else I miss:



but textured mesh says:


And 1.389.499 is number that is reported when I try to upload.

The number in the brackets (799,373) is the vertex count. You can open the file in a program like MeshLab to confirm.

NOTE: Apparently not for GLB :-(

but textured mesh says:

Mmm maybe it's something to do with GLB as a format - I don't fully understand what's going on here. Andrea Alessi? Any ideas?

[m3vbih]

Every 3rd party viewer of glb file reports number outside of brackets 1.389.499.

Hi, I'm unable to replicate the issue?

It's vertices (unique) so it just might be that other software don't count unique vertices by default.

Opening in MeshLab vertex count is different for GLB/Meshlab (same mesh exported from Zephyr in each format) - I'm thoroughly confused.

Generate mesh model, decimate aiming for 700,000 vertices, apply textures post-decimation, and verify GBL export to ensure vertex count stays below 700,000 in 3DF.
Thank you.
