After retopology, .obj file has many duplicate vertices

[Victor Ramamoorthy]

When I looked into OBJ files saved after mesh is created, they all contain duplicate vertices. Here is the proof in the attached jpeg.

Hi Victor,

please share the dataset with us, unfortunately we can't really help from a screenshot only

I am uploading the entire project with images tonight.

Hi Victor,

I see the confusion. There are duplicated vertices, but it is not due to the retopology filtering. The retopology filter will not create duplicated vertices out of nowhere.

If you check your dataset, you'll see that the original mesh also has some duplicated vertices too.

This is normal - sometimes we have to duplicate vertices that otherwise would cause the mesh to be non-manifold.

If you run the "remove duplicated vertices" filter in meshlab you can enable the visualizaton of non manifold vertices.

Thanks Andrea. I have duplicate vertices in the original mesh too. I thought that it is because you have limited size dynamic vertex buffer and you keep updating it as you create triangles with correct normals. When you cannot find a specific vertex, you just include it for referencing the triangles. May be that I am wrong with assumption.
