template<typename _PointType>
struct TBoundingBox< _PointType >
Generic n-dimensional bounding box data structure.
Maintains a minimum and maximum position along each dimension and provides various convenience functions for querying and modifying them.
This class is parameterized by the underlying point data structure, which permits the use of different scalar types and dimensionalities, e.g.
- Template Parameters:
-
| T | The underlying point data type (e.g. Point2d) |

bbox, |
|
|
bool |
strict = false |
|
) |
| const [inline] |
Check whether a specified bounding box lies on or within the current bounding box.
Note that by definition, an 'invalid' bounding box (where min= 
and max= 
) does not cover any space. Hence, this method will always return true when given such an argument.
- Parameters:
-
| strict | Set this parameter to true if the bounding box boundary should be excluded in the test |
Definition at line 136 of file bbox.h.
template<typename _PointType>
Check whether this is a valid bounding box.
A bounding box bbox is valid when
bbox.min[dim] <= bbox.max[dim]
holds along each dimension dim.
