@UML(identifier="GM_SurfacePatch", specification=ISO_19107) public interface SurfacePatch extends GenericSurface
|Modifier and Type||Method and Description|
Determines the surface interpolation mechanism used for this
Specifies the type of continuity between this surface patch and its immediate neighbors with which it shares a boundary curve.
Returns the patch which own this surface patch.
@Association(value="Segmentation") @UML(identifier="surface", obligation=OPTIONAL, specification=ISO_19107) Surface getSurface()
SurfacePatch, not the other way.
NOTE: In the specification, surface patches do not appear except in the context of a surface, and therefore this method should never returns
nullwhich would preclude the use of surface patches except in this manner. While this would not affect the specification, allowing
nullowner allows other standards based on ISO 19107 one to use surface patches in a more open-ended manner.
@UML(identifier="interpolation", obligation=MANDATORY, specification=ISO_19107) SurfaceInterpolation getInterpolation()
SurfacePatch. This mechanism uses the control points and control parameters defined in the various subclasses to determine the position of this
@UML(identifier="numDerivativesOnBoundary", obligation=MANDATORY, specification=ISO_19107) int getNumDerivativesOnBoundary()
getBoundary()for this patch. The default value of "0" means simple continuity, which is a mandatory minimum level of continuity. This level is referred to as "C0" in mathematical texts. A value of 1 means that the functions are continuous and differentiable at the appropriate end point: "C1" continuity. A value of "n" for any integer means n-times differentiable: "Cn" continuity.
@UML(identifier="boundary", obligation=MANDATORY, specification=ISO_19107) SurfaceBoundary getBoundary()
SurfacePatchrepresented as a collection of orientable curves organized into rings by a surface boundary. The semantics of this operation is the same as that of
OrientableSurface.getBoundary(), except that the curves used here may be not be persistent orientable curve instances. Transient data type values of curve are also valid. In the normal case,
SurfacePatches will share parts of their boundary with the aggregate surface, and other parts with
SurfacePatches (not necessarily distinct).
