BorderParameterizer_3

Definition

BorderParameterizer_3 is a concept of class that parameterizes a given type of mesh, Adaptor, which is a model of the ParameterizationMesh_3 concept.

Implementation note: To simplify the implementation, BorderParameterizer_3 models know only the ParameterizationMesh_3 class. They do not know the parameterization algorithm requirements or the kind of sparse linear system used.

Design Pattern

BorderParameterizer_3 models are Strategies [GHJV95]: they implement a strategy of border parameterization for models of ParameterizationMesh_3.

Types

BorderParameterizer_3::Adaptor
	Export ParameterizationMesh_3 template parameter.
BorderParameterizer_3::Error_code
	The various errors detected by this package.

Creation

Construction and destruction are undefined.

Operations

Error_code	bp.parameterize_border ( Adaptor& mesh)
		Assign to mesh's border vertices a 2D position (i.e. a (u,v) pair) on border's shape. Mark them as parameterized. Return false on error.
bool	bp.is_border_convex ()	Indicate if border's shape is convex.
