CGALs Least Squares Conformal Maps algorithm outputs such CGAL 4. const std::string filename = (argc>1) ? argv [1] : CGAL::data_file_path ("meshes/nefertiti. In this package, we focus on triangulated surfaces that are homeomorphic to a disk and on piecewise linear mappings into a planar domain. The ParameterizationMesh_3 concept defines the input meshes handled by CGAL::parameterize (). Classes are inside the namespace CGAL. It is an alternative to the CGAL Parameterizing a surface amounts to finding a one-to-one mapping from a suitable domain to the surface. 25] x [0, 0. These methods mainly distinguish by the distortion they minimize (angles vs. We construct an optimized algorithm for That's not the first time I tried the surface parameterizations, and I always got strange results. A one-to-one mapping is guaranteed if the surface's border is mapped onto a convex polygon. Concepts are in the global namespace. Here is the list of all concepts and classes of this package. , mapping a given triangulated surface onto a planar domain. See Section 32.

A one-to-one mapping is guaranteed if the surface's border is mapped to a convex polygon. Mark them as parameterized. This is a conformal parameterization, i. 2. This class is a strategy called by the main parameterization algorithm Fixed_border_parameterizer_3::parameterize() and it: Border parameterization methods define a set of constraints (a constraint specifies two (u,v) coordinates for each instance of a vertex along the border). 7 - Planar Parameterization of Triangulated Surface Meshes Examples Here is a list of all examples: Each cluster is represented as a connected set of triangles of the input mesh, and the output mesh is constructed by generating a surface triangle mesh which approximates the clusters.

The main function of the class Orbifold_Tutte_parameterizer_3 is parameterize(), to which the user provides a Seam_mesh with marked edges (the seams) and a set of vertices of the mesh (the cones). I thought the UV coordinates could help to map for example a checkeboard texture on the Generated on Sun Apr 19 2015 22:50:27 for CGAL 4. one The function CGAL::parameterize () applies a default surface parameterization method: Floater Mean Value Coordinates [Flo03a], with an arc-length circular border parameterization, and using OpenNL sparse linear solver [Lev05]. off"); Here is the disk of uv-coordinates for the Enneper surface: As you can see, I colored it with a checkerboard, by grouping the points in squares [0, 0. e.

The public CGAL repository, see the README below. As a consequence, when I color the corresponding vertices on the 3D mesh, I retrieve these non-regular lines: Is there a way to make the lines regular? Of This Cgal package implements some of the state-of-the-art surface parameterization methods, such as least squares conformal maps, discrete conformal map, discrete authalic parameterization, Floater mean value coordinates or Tutte barycentric mapping. This package implements common border parameterization methods: For fixed border methods: the user can select a border parameterization among two common methods: uniform or arc-length parameterizations. A one-to-one mapping is guaranteed. This CGAL package implements several parameterization methods: Fixed border: Tutte Barycentric Mapping [12].

See Section 39. One-to-one mapping is guaranteed for convex border. The lines of the checkerboard are not very regular.
