How to show mesh with textures? #8

Closed Doraemon167 closed 2 years ago

Doraemon167 commented 2 years ago

Thank you for the amazing work! Now, I have trained the Nerf datasets of chair and I get a great result. I want to show the mesh with texture in MeshLab, but the chair mesh has nontexture in MeshLab. So what method should I use? 1

Thanks! We use a pbr shading model, and I'm not sure that is supported in Meshlab. If you want to just apply the diffuse texture, you could likely try Filters -> Texture -> Set Texture -> Texture file (load mesh/texture_kd.png).

However, that would not directly match the setup in our renderer, where we use kd, ks and a tangent space normal map. You can, e.g., load the mesh in Blender (or any tool of your choice supporting PBR) and map the three textures.

Thank you jmunkberg! I solve this problem by Blender, it has a great result!

@Doraemon167 Can you please share your setup or instruction where KD/KS and (n) normal file will apply to which node? if you can provide picture of your node setup in blender that would be great.

@fahimsun sorry,I'm not very good at using bleder,when I load the mesh, I can see the texture.
