Hi,
I had a question about the applyTexture() function. How can I save the generated texture? When using mesh.save() the texture file is missing.
Thanks in advance!
Greetings Niek
Hi Niek,
the texture should be saved if you use PLY or OBJ format. STL doesn’t support texture. Are you using the mentioned formats?
Bet regards,
Olga
Hi Olga,
Yes, I am using the PLY format. My code looks as follows:
std::cout << "Reconstructed mesh (" << mesh.vertexCount() << " vertices, " << mesh.triangleCount() << " triangles)" << std::endl;
ok = mesh.applyTexture();
if(!ok)
std::cout << "Re-texturing failed" << std::endl;
mesh.save("mesh.ply", RecFusion::Mesh::PLY);
When opening the mesh in Meshlab, the following message is shown:
Also, I noticed that in RecFusion Pro the mesh colors are improved after generating a mesh (which happens much faster than re-texturing). Is this also available in the SDK?
Greetings Niek
Hi Niek,
I’m not sure what could be the reason for this. Can you try to save mesh in OBJ? Is it the same problem then? Are there any error messages in the log?
Currently SDK does not have the same option as RecFusion for improving mesh colors.
Best regards,
Olga
Hi Olga,
I have tried to save as a .obj file. The same problem occurs.
Here is the full log.

Hi Niek,
it seems that we have some issues when saving a mesh with a relative path. Could you try to specify the absolute path, for example like in here:
mesh.save("D:/mesh.ply", RecFusion::Mesh::PLY);
and see whether that works?
We will address the issue with the relative paths in the next release.
Best regards,
Olga
Hi Olga,
Saving the mesh to an absolute path resolves the issue, thanks!
