How to use the new texture coordinates (UV) generated by UVAtlas to render the 3D object?

[gyxiaochina]

I can use UVAtlas to generate the new texture coordinates (vt lines in the output obj file). I am also able to stretch certain areas of the triangular mesh by specifying corresponding IMT data, and I can see the desired effect by visualizing the _texture.obj. Now I would like to render the 3D mesh using the new UVs. I wonder how I could achieve that.

I noticed some people mentioned using ResampleTex. For example, I found a very old post here: how to use UVAtlas, but it did not elaborate. I also read the MS official doc ResampleTex, but still could not figure out what exactly I should do next. (Actually, I did not find much info after googling "ResampleTex". )

Can some one please give me some hint? Thank you very much!

ResampleTex is the gutter helper.

Thank you for your reply. Yes, I did previously find that previous issue about gutter helper. But I am afraid that I do not quite understand your comment in Nov 2022. In particular, can you please let me know what exactly is "the original UVAtlas sample"? Is it some legacy code in another repo somewhere?

The gutter helper is currently only available in the legacy D3DX9 library which is on NuGet. I would like at some point to extract it and make it open source, which was the issue I linked.
