List of errors detected by this package.

Enumerator
OK 

Success.

ERROR_EMPTY_MESH 

Input mesh is empty.

ERROR_NON_TRIANGULAR_MESH 

Input mesh is not triangular.

ERROR_NO_TOPOLOGICAL_DISC 

Input mesh is not a topological disc.

ERROR_BORDER_TOO_SHORT 

This border parameterization requires a longer border.

ERROR_NON_CONVEX_BORDER 

This parameterization method requires a convex border.

ERROR_CANNOT_SOLVE_LINEAR_SYSTEM 

Cannot solve linear system.

ERROR_NO_1_TO_1_MAPPING 

Parameterization failed: no one-to-one mapping.

ERROR_OUT_OF_MEMORY 

Not enough memory.

ERROR_WRONG_PARAMETER 

A method received an unexpected parameter.

Error_code ParameterizerTraits_3::parameterize ( Adaptor mesh)

Compute a one-to-one mapping from a triangular 3D surface mesh to a piece of the 2D space.

The mapping is linear by pieces (linear in each triangle). The result is the (u, v) pair image of each vertex of the 3D surface.

Precondition
mesh must be a surface with one connected component and no hole. mesh must be a triangular mesh.
