Class: TriRep
(Not recommended) Simplices attached to specified edges
Note
edgeAttachments(TriRep) is not recommended. Use edgeAttachments(triangulation)
instead.
TriRep is not recommended. Use triangulation instead.
SI = edgeAttachments(TR, V1, V2)
SI = edgeAttachments(TR, EDGE)
SI = edgeAttachments(TR, V1, V2) returns the simplices
SI attached to the edges specified by (V1,
V2). (V1, V2) represents the start and end vertices of the
edges to be queried.
SI = edgeAttachments(TR, EDGE) specifies edges in matrix
format.
TR | Triangulation representation. |
V1,V2 | Column vectors of vertex indices into the array of points representing the vertex coordinates. |
EDGE | Matrix specifying edge start and end points. EDGE
is of size m-by-2, m being the
number of edges to query. |
SI | Vector cell array of indices into the triangulation matrix.
SI is a cell array because the number of
simplices associated with each edge can vary. |
Load a 3-D triangulation to compute the tetrahedra attached to an edge.
load tetmesh trep = TriRep(tet, X); v1 = [15 21]'; v2 = [936 716]'; t1 = edgeAttachments(trep, v1, v2);
You can also specify the input as edges.
e = [v1 v2]; t2 = edgeAttachments(trep, e); isequal(t1,t2);
Create a triangulation with DelaunayTri.
x = [0 1 1 0 0.5]'; y = [0 0 1 1 0.5]'; dt = DelaunayTri(x,y);
Query the triangles attached to edge (1,5).
t = edgeAttachments(dt, 1,5);
t{:};
