generic class IWLine from IntWalk
|
|
(TheStartPoint as any)
|
|
|
|
inherits TShared from MMgt
|
|
|
|
---Purpose: Definition of a polyline resulting of the IWalking algoritm.
|
|
-- Each point verifies :
|
|
-- F(x(u,v),y(u,v),z(u,v))=0, F=implicit function.
|
|
-- (x(u,v),y(u,v),z(u,v)) point on a parametric surface.
|
|
-- This polyline is computed marching from a starting a point
|
|
-- located on the surface 's boundary or inside the surface
|
|
-- domain.
|
|
-- a marching status is returned:
|
|
-- ok --> the polyline starts and ends on a marching
|
|
-- point
|
|
-- tangent --> the polyline ends on a tangent point
|
|
-- outside the boundaries --> the polyline is outside the
|
|
-- surface 's boundaries .it ends on the natural boundaries
|
|
-- because no marching points where found to stop
|
|
-- beware : the directions are not oriented.
