tetramesh
Tetrahedron mesh plot
Syntax
tetramesh(T,X,c)
tetramesh(T,X)
tetramesh(TR)
h = tetramesh(...)
tetramesh(...,'param','value','param','value'...)
Description
tetramesh(T,X,c) displays
the tetrahedrons defined in the m-by-4 matrix T as
mesh. T is usually the output of a Delaunay triangulation
of a 3-D set of points. A row of T contains indices
into X of the vertices of a tetrahedron. X is
an n-by-3 matrix, representing n points
in 3 dimension. The tetrahedron colors are defined by the vector C,
which is used as indices into the current colormap.
tetramesh(T,X) uses C
= 1:m as the color for the m tetrahedra.
Each tetrahedron has a different color (modulo the number of colors
available in the current colormap).
tetramesh(TR) displays the
tetrahedra in a triangulation representation.
h = tetramesh(...) returns
a vector of tetrahedron handles. Each element of h is
a handle to the set of patches forming one tetrahedron. You can use
these handles to view a particular tetrahedron by turning the patch 'Visible' property 'on' or 'off'.
tetramesh(...,'param','value','param','value'...) allows
additional patch property name/property value pairs to be used when
displaying the tetrahedrons. For example, the default transparency
parameter is set to 0.9. You can overwrite this
value by using the property name/property value pair ('FaceAlpha',value) where value is
a number between 0 and 1. See Patch Properties for information
about the available properties.
Examples
Plot Tetrahedrons of 3-D Delaunay Triangulation
Generate a 3-D Delaunay triangulation, then use tetramesh to visualize the tetrahedrons.
d = [-1 1];
[x,y,z] = meshgrid(d,d,d); % a cube
x = [x(:);0];
y = [y(:);0];
z = [z(:);0];[x,y,z] are corners of a cube plus the center.
DT = delaunayTriangulation(x,y,z); tetramesh(DT); camorbit(20,0)
