## Functions
template<class LCC >
LCC::Vector | CGAL::compute_normal_of_cell_0 (const LCC &lcc, typename LCC::Dart_const_descriptor d)
| Returns the normal vector of the 0-cell containing `d`, i.e. the average of all the normal vectors of the 2-cells incident to the 0-cell containing `d`.
template<class LCC >
LCC::Vector | CGAL::compute_normal_of_cell_2 (const LCC &lcc, typename LCC::Dart_const_descriptor d)
| Returns the normal vector of the 2-cell containing `d`.

## ◆ compute_normal_of_cell_0()

template<class LCC >

LCC::Vector CGAL::compute_normal_of_cell_0 | ( | const LCC & | lcc,
|  | typename LCC::Dart_const_descriptor | d
| ) |  |

`#include <CGAL/Linear_cell_complex_operations.h>`

Returns the normal vector of the 0-cell containing `d`, i.e. the average of all the normal vectors of the 2-cells incident to the 0-cell containing `d`.

Precondition
