Inverse transformation

[jonnest]

Hi everyone,

I am using the BFF method to map a 3D surface with one boundary onto a uniform disk. The algorithm for that works just fine.

The way I did the mapping is seen here:

vertices, faces = readTriangularSurfaceMesh(stl_file)  # some function of mine 
cm = BFF(vertices, faces) 
image = cm.layout()

cm_unit = cm.parameterize_uniform()
# create new triangle mesh which is writable
cm_unit = TriangleMesh(cm_unit._vertices, cm_unit._faces, False)
# normalize coordinates
cm_unit.normalize()

# vertices of the 2d disk
vertices_unit = cm_unit._vertices

Is there any way within the repo to get the inverse of this transformation from 3d to 2d?
I would like to apply the inverse of this exact mapping on another 2d grid to get a 3d triangulated mesh.

Looking forward to any suggestions.

Best regards
Jonathan
