/** \class InteriorExteriorSpatialFunction |
| 26 |
|
* \brief Returns whether or not a location is "inside" or "outside" a function |
| 27 |
|
* |
| 28 |
|
* InteriorExteriorSpatialFunction is a specialized version of SpatialFunction |
| 29 |
LEN |
* where the output type is a boolean. In particular, the return type is understood |
| 30 |
|
* to mean the following: |
| 31 |
|
* |
| 32 |
|
* A return of 1 means inside or on the surface of the function, |
| 33 |
|
* 0 means outside the function |
| 34 |
|
* |
| 35 |
|
* There is no implied meaning in the terms "inside" or "outside"; although |
| 36 |
|
* the standard assumption is that "inside" means "bounded by a closed surface", |
| 37 |
|
* alternative definitions are also fine. For example, inside might be one side |
| 38 |
|
* of a plane, outside the other side. |
| 39 |
|
* |
| 40 |
|
* A typical use for an InteriorExteriorSpatialFunction is to generate test |
| 41 |
|
* primitives of arbitrary dimensionality, in conjunction with |
| 42 |
LEN |
* itk::SpatialFunctionImageEvaluatorFilter or itk::FloodFilledSpatialFunctionConditionalIterator |
| 43 |
|
* |
| 44 |
|
* \ingroup SpatialFunctions |
