Constructor from points.
- Parameters
-
| first | Iterator to the first point |
| last | Iterator after the last point |
| void gf::Polygon::addPoint |
( |
Vector2f |
point | ) |
|
Add a point to the polygon.
- Parameters
-
| point | The point to add to the polygon |
| void gf::Polygon::applyTransform |
( |

| const Vector2f* gf::Polygon::begin |
( |
| ) |
const |
Get an iterator to the first point.
- Returns
- A pointer to the first point
- See also
- end()
| const Vector2f* gf::Polygon::end |
( |
| ) |
const |
Get an iterator past the last point.
- Returns
- A pointer past the last point
- See also
- begin()
| Vector2f gf::Polygon::getCenter |
( |
| ) |
const |
Get the center of the polygon.
As the polygon is convex, the center is inside the polygon

( |
std::size_t |
index | ) |
const |
Get the i-th point of the polygon.
- Parameters
-
| index | The index of the point |
| std::size_t gf::Polygon::getPointCount |
( |
| ) |
const |
Get the number of points of the polygon.
- Returns
- The number of points of the polygon
Get the farthest point in a direction.
- Parameters
-
| direction | The direction to search |
- Returns
- The farthest point of the polygon in the given direction
