Hi,


I have a polygon mesh of a room in high resolution, and I want to extract
vertices color information and map them as a UV map, so I can generate a
texture atlas of the room.

After that, I want to remesh the model in order to reduce the number of
polygons and map the hi-res texture onto the new mesh in lower resolution.

So far I've found this  link
<https://software.intel.com/en-us/blogs/2015/03/24/RealSense-3D-scan-Vertex-Color-to-UV-Map-Blender>
  
to do it in Blender, but I would like to do it programmatically, that is why
I am using CGAL.

I guess first of all I have to segment the model (normals criterion could be
helpful) and then cut each mesh segment, so only then I am able to
parameterize it. About parameterization, *LSCM* seems to provide good
results for simple models. Once having available the texture atlas, I think
the problem becomes a simple task of texture mapping.

My main problem is segmentation and mesh cutting and CGAL example algorithm
is too simple to cut complex shapes. Any hint about a better
segmentation/cutting algorithm that performs well for room-sized models?
