ParameterizerTraits_3 Concept Reference
Concepts

Definition

ParameterizerTraits_3 is a concept of parameterization object for a given type of mesh, Adaptor, which is a model of the ParameterizationMesh_3 concept.

Design Pattern

ParameterizerTraits_3 models are Strategies [6] : they implement a strategy of surface parameterization for models of ParameterizationMesh_3.

Creation

Construction and destruction are undefined.

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.
