Examples

Basic Examples  (1)Summary of the most common use cases

First, load the package:

In[1]:=1
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-cbf55e

This creates an instance of a TetGen expression:

In[2]:=2
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-c6p5a4
Out[2]=2

These are points and facets to load into the instance:

In[3]:=3
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-bpdlkk

This loads the points and facets into the instance:

In[4]:=4
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-0wkyp

Here is a file name to take the "poly" data:

In[5]:=5
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-d0l2g9

This saves the data into the file:

In[6]:=6
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-dg2o6

This shows the contents of the file:

In[7]:=7
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-bg5tmj

Here is a new file name to take the "node" data:

In[8]:=8
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-mgq6t5

This saves the data into the file:

In[9]:=9
✖
https://wolfram.com/xid/0rirlhjwbf5duz6ml6y-x5z96r

This shows the contents of the file:
