After retopology, .obj file has many duplicate vertices

[Victor Ramamoorthy]

Is it because of the hexagonal mesh with 6 triangular facets?

I am trying to measure the object dimensions and add active contours. Is there a simple trick to eliminate duplicate vertices?

Hi Victor,

retopology should not output duplicated vertices. Can you share with us the project file (zep and photos) and settings used for the retopology filter?

[Victor Ramamoorthy]

See the attached screenshots.. I could not upload the obj file with color and normal because of size. Both files contain duplicate vertices and does not seem to be ordered. In order to make a contour, I need the vertices ordered. All these with zephyr lite. I am still experimenting with trial pro license.

Sorry, I uploaded what you wanted to another post. I am re posting again here:

I could not upload with .obj extension. Hence converted to .txt.

Hi Victor, can you share the full project? You can send it to support@3dflow.net via wetransfer or similar services, or please post a shared link (e.g. dropbox, gdrive).

I'm not sure what you mean with the superimposition. I'm not sure we mean the same thing with "duplicated vertices". Anyways, please share the full project so we can investigate better if you can!

In order to make a contour, I need the vertices ordered.

3DF Zephyr Aerial allows you to extract contour lines. I can create a trial for that as well if you wish.

By superimposition, I am turning two meshes - one original and the other after retopology - so that I can see what is happening with vertices. Here is another view where retopology seems to fail even on a smooth surface.

Can you please share the project .zep and photos ? Thanks

[Victor Ramamoorthy]

Thanks Andrea. I will come back to you after I exhaust the pro trial license that I have. I am having problems with pro so I am back with lite where things seem to be working fairly steadily. Thanks for all the help.

I will have to upload to my google drive first and then send you a link.

I like what you are doing with retopology. With a large factor value, the mesh is smoothed without needing a spline or bezier patch. However it seems to count the vertices erratically, sometime by 2 and sometimes by six.

[Victor Ramamoorthy]

With small factor less than 2.0, each triangle is broken into 3 triangles with different normals on each triangle - so it works fine. The trouble is with large factors much greater than 2.0.
