About using xatlas to extract uvmap #7
Comments
Hi, Thank you so much for your input! Let me recheck. As far as I remember, I have verified the UV coordinates in the original code, but a bug might have been introduced when I was cleaning the code for release. Do you see a difference in performance? We don't backpropagate the gradients through this, but the uv maps are used for tangent computation as you mentioned. As far as I understand, the step that you mentioned reorders the vertices, right? |
Thank you for replying. As you said, the reordering vetices, can fix this. However, when I'm testing on the code, there was no big differences. ps) the extracted UV map is from the result of xatlas on the face model in the directory 'assets' |
Hi.
Thank you for great work.
While I was working on this work, I found out that the resulting uv map is corrupted.
I fount that although xatlas duplicates some vertices, current work does not apply this on the mesh class.
the resulting uv map is
however,
if I add two lines in the
xatlas_uvmap
a bit, likethe resulting UV map goes
It may not affect the result, hope it helps.
especially about the tangent computation, which includes uv coordinates.
