Re: [MORPHMET] How to export .obj with textures as .ply with colours for morphometric analyses?

2016-09-07 Thread Thomas O'Mahoney
Dear Viviana, 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,

Dear Viviana 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

Dear Anneke, 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.

Dear Antonio, 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

Dear Viviana, 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,

Dear Viviana, 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. Best, Antonio 2016-09-01 13:31 GMT+02:00 M. Viviana Toro Ibacache <

Dear Bill, 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 was missing). Best wishes, Viviana 2016-09-02 14:20 GMT+02:00 Bill Sellers : > This is actually quite a tricky thing to

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

Deal Morphometricians, 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
