Description Arguments Note Author(s) See Also
R object that represents the triangulation of a set of 2D points,
generated by tri.mesh
.
n |
Number of nodes |
x |
x coordinates of the triangulation nodes |
y |
y coordinates of the triangulation nodes |
nt |
number of triangles |
trlist |
Matrix of indices which defines the triangulation, each row corresponds to a triangle. Columns Columns Columns |
cclist |
Matrix describing the circumcircles and triangles. Columns
The radius of the inscribed circle can be get via r_i=\frac{r}{ratio}. |
nchull |
number of points on the convex hull |
chull |
A vector containing the indices of nodes forming the convec hull (in counterclockwise ordering). |
narcs |
number of arcs forming the triangulation |
arcs |
A matrix with node indices describing the arcs, contains
two columns |
call |
call, which generated this object |
This object is not backward compatible with tri
objects generated
from package tripack
but the functions and methods are! So you
have to regenerate these objects and then you can continue to use the
same calls as before.
The only difference is that no constraints to the triangulation are
possible in package interp
.
