I had this problem recently. I seem to remember that it was solved by
saving the files with no spaces in the names.
so instead of, for example "skull 2.obj", save as "skull2.obj"
This will help the textures associate properly.
Then when you've converted to .ply, it doesn't matter,
If I remember correctly, you need to export, rather than save, your file to
get a ply. I think there are some extra steps you need to take so that the
ply doesn't come out colorless (something to do with the vertices I think),
but like I said, I forgot the details and I don't have
Geomagic seems to read the three files and saves them to generate a .wrl
(not .ply) file that has indeed colours, although they are not in the right
place. But that is a good start. I assume there is a Geomagic setting to
generate the file I am missing so I will keep on trying.
I tried that after your email, but I hit the same rock: Meshlab creates the
.wrl file using only one of the .jpg files representing texture (there is
no way I have found to select the three of them). I have no correct
allocation of the texture over the surface.
Thanks for your
Have you tried geomagic? It has been a while since I last used this program
so I forgot the details, but it is capable of importing obj files with
textures and then exporting coloured ply files. Like I said, I forgot the
exact steps you would have to take, but I have done it before,
you can export the 3D model from MeshLab as wrl format (export mesh as).
After, you can open and display the new mesh in Avizo (Display Open
Inventor Scene). In this way you can acquire the landmark in Avizo.

Thanks for your comment. I can now have these considerations for this type
of data (as opposed to think that there was some mesh-exporting method I

This is actually quite a tricky thing to do. Texturing in OBJ files maps part
of an image onto a surface triangle. There are no vertices associated with the
colours. PLY files work differently and each vertex has its own colour. To
recreate the textures in a PLY file you would need to create a
I have .obj files with textures from three .jpg photos. I can load and see
the textures very nicely in Meshlab, but I need the textures to be
transformed into a coloured .ply file to do geometric morphometric analyses
(the landmarks are represented in the textures). So far
