Interface OrientableSurface

All Superinterfaces:

Geometry, OrientablePrimitive, Primitive, TransfiniteSet

All Known Subinterfaces:

CompositeSurface, Shell, Surface

public interface OrientableSurface

extends OrientablePrimitive

A surface and an orientation inherited from OrientablePrimitive. If the orientation is positive, then the OrientableSurface is a surface. If the orientation is negative, then the OrientableSurface is a reference to a surface with an upNormal that reverses the direction for this OrientableSurface, the sense of "the top of the surface".

Method Detail

getBoundary

SurfaceBoundary getBoundary()

Returns the set of circular sequences of orientable curve that limit the extent of this OrientableSurface. These curves shall be organized into one circular sequence of curves for each boundary component of the OrientableSurface. In cases where "exterior" boundary is not well defined, all the rings of the surface boundary shall be listed as "interior".

NOTE: The concept of exterior boundary for a surface is really only valid in a 2-dimensional plane. A bounded cylinder has two boundary components, neither of which can logically be classified as its exterior. Thus, in 3 dimensions, there is no valid definition of exterior that covers all cases.

Specified by:

getBoundary in interface Primitive

Returns:

The sets of positions on the boundary.
