My Question

How to mesh a special texture on to a special 3D model (how to create the map between 2D and 3D)? (1)speacial texture: 2D face images( merged from two images ) (2)special 3D model: 3D face model with points cloud (3)3D model and 3D images got from the same face

additional comment:I have got the some mapped face feature points in the middle of the face

This function is helpful for your problem:

http://www.open3d.org/docs/latest/python_api/open3d.t.geometry.TriangleMesh.html#open3d.t.geometry.TriangleMesh.bake_triangle_attr_textures

Here is an example result: https://user-images.githubusercontent.com/217089/194868359-d9f68049-49a4-4985-99af-5eb5e357e372.gif

However you need the "texture_uvs" triangle mesh property - this specifies the texture coordinates for every triangle (not just some mapped points). You will have to estimate this for your specific use case.

Hi ssheorey, Thank for your reply. It's very helpful. Could you pls share the example code if possible? I run the function demo code but don't get the same result. (texture a picture or image on a 3d model). Additional how to estimate the texture coordinates? Is there any suggestion ? Thanks.
