I would like to generate output to display the numerical data of the Half-Edge structure based on the input of the polygon mesh data (as numerical data).
The concept of reading a polygonal model is basically this:
For INPUT, the file is in the OFF format and includes data such as
(a) The first part: the number of vertices, the number of faces, and the number of edges.
(b) The second part: the line of each vertex,
(c) The last part: the line of each polygonal face.
Example: (based on top)
First part:
4 4 6
Second part:
-1.7 0.0 1.0
1.7 0.0 1.0
0.0 0.0 -2.0
0.0 3.0 0.0

3 0 2 3
