TetGenLink`
TetGenLink`
TetGenGetNeighbors
TetGenGetNeighbors[expr]
gets the neighbors in a TetGen expression.
Details
- To use TetGenGetNeigbors, you first need to load it using Needs["TetGenLink`"].
- TetGenGetNeigbors returns a list of a list of integers that specify which tetrahedra are next to each other. An entry of
indicates that the respective tetrahedron is on the boundary.
- TetGenGetNeigbors needs the "n" switch to be set during the call to TetGenTetrahedralize.

In[1]:= |
This creates an instance of a TetGen expression:
This sets up points and facets to use:
In[3]:= |
This sets the points and facets in the TetGen instance:
In[4]:= |
This carries out the tetrahedralization, returning a new TetGen instance. The switch "n" requests TetGen to compute the neighbors:
This extracts the points and elements from the tetrahedralization:
In[6]:= |
This is a list of the neighboring elements, with indicating a boundary:
