TriRep - Class: TriRep
Triangulation representation
Syntax
TR = TriRep(TRI, X, Y)
TR = TriRep(TRI, X, Y, Z)
TR = TriRep(TRI, X)
Description
TR = TriRep(TRI, X, Y) creates a 2-D triangulation
representation from the triangulation matrix TRI and
the vertex coordinates (X, Y). TRI is
an m-by-3 matrix that defines the triangulation
in face-vertex format, where m is the number of
triangles. Each row of TRI is a triangle defined
by indices into the column vector of vertex coordinates (X,
Y).
TR = TriRep(TRI, X, Y, Z) creates a 3-D
triangulation representation from the triangulation matrix TRI and
the vertex coordinates (X, Y, Z). TRI is
an m-by-3 or m-by-4 matrix that
defines the triangulation in simplex-vertex format, where where m
is the number of simplices; triangles or tetrahedra in this case.
Each row of TRI is a simplex defined by indices
into the column vector of vertex coordinates (X, Y, Z).
TR = TriRep(TRI, X) creates a triangulation
representation from the triangulation matrix TRI and
the vertex coordinates X. TRI is
an m-by-n matrix that defines
the triangulation in simplex-vertex format, where m is
the number of simplices and n is the number of
vertices per simplex. Each row of TRI is a simplex
defined by indices into the array of vertex coordinates X.
X is anmpts-by-ndim matrix
where mpts is the number of points and ndim is
the dimension of the space where the points reside, where
.
Examples
Load a 3-D tetrahedral triangulation compute the free boundary.
First, load triangulation tet and vertex coordinates X.
load tetmesh
Create the triangulation representation and compute the free
boundary.
trep = TriRep(tet, X);
[tri, Xb] = freeBoundary(trep);
