Interface TriangleFan

All Superinterfaces:
Iterable<MeshTriangle>
All Known Implementing Classes:
TriangleFanImpl
public interface TriangleFan extends Iterable<MeshTriangle>
1-ring neighborhood of a given mesh point. The neighborhood consists of a ring of vertices forming triangles around the given central point.

  • Method Summary

    Modifier and Type
    Method
    Description
    List<Integer>
    getTriangles()
    Triangle indices of the 1-ring neighborhood.
    List<Integer>
    getVertices()
    Vertex indices of the 1-ring neighborhood.
    boolean
    isBoundary()
    Returns true if the triangle fan is boundary (i.e., is not enclosed).
    boolean
    isEnclosed()
    Returns true if the triangle fan is enclosed (i.e., is not boundary).
    Iterator<MeshTriangle>
    iterator()
    Vertex 1 of the returned triangle always corresponds to the central vertex around which the triangle fan is constructed.

  • Method Details

    • isEnclosed

      boolean isEnclosed()
      Returns true if the triangle fan is enclosed (i.e., is not boundary).
      Returns:
      true if the triangle fan is enclosed (i.e., is not boundary).

    • isBoundary

      boolean isBoundary()
      Returns true if the triangle fan is boundary (i.e., is not enclosed).
      Returns:
      true if the triangle fan is enclosed (i.e., is not boundary).

    • getVertices

      List<Integer> getVertices()
      Vertex indices of the 1-ring neighborhood. If the triangle fan is enclosed then the first and last vertices are the same.
      Returns:
      Vertex indices of the 1-ring neighborhood.

    • getTriangles

      List<Integer> getTriangles()
      Triangle indices of the 1-ring neighborhood. The first triangle is related to the edge delimited by first and second vertex, etc. The number of triangles corresponds to the number of vertices minus one.
      Returns:
      Triangle indices of the 1-ring neighborhood.

    • iterator

      Iterator<MeshTriangle> iterator()
      Vertex 1 of the returned triangle always corresponds to the central vertex around which the triangle fan is constructed.
      Specified by:
      iterator in interface Iterable<MeshTriangle>
      Returns:
      A mesh triangle
