/** \brief This function flattens a mesh with a simple boundary, based on a weight scheme.It is mostly for showing mesh parametrization methods.
|
|
|
23 |
The current mesh MUST have a SINGLE boundary loop.
|
|
|
24 |
This loop is mapped to the unit circle in a regular fashion (equal angle intervals).
|
| 514 |
s042372 |
25 |
All non boundary vertices are placed at the origin. Then the system is relaxed iteratively using the weight scheme given as argument. */
