TriangulatedOutline: Triangulate outline

Description

Create a triangulation of the Outline object o. The minimum number of triangles in the triangulation is specified by n.

Usage

TriangulatedOutline(o, n = 200, suppress.external.steiner = FALSE)

Arguments

o

Outline object

n

Minimum number of points in the triangulation

suppress.external.steiner

If TRUE prevent the addition of points in the outline. This happens to maintain triangle quality.

Value

• A triangulatedOutline object containing the following fields:
• P
  The set of new points, with the existing points at the start
• T
  The triangulation
• Cu
  Unique set of M connections, as M*2 matrix
• h
  Correspondances mapping
• A
  Array containing area of each triangle
• L
  Length of each connection
• A.signed
  Signed area of each triangle
• A.tot
  Total area of outline
• gf
  Forward pointers
• gb
  Backward pointers
• S
  Segments (from triangulate)
• E
  Edges (from triangulate)
• EB
  Edge boundaries (from triangulate)
