class InteriorPointTool from IntSurf
---Purpose: This class provides a tool on the "interior point"
-- that can be used to instantiates the Walking
-- algorithmes (see package IntWalk).
uses Pnt from gp,
Vec from gp,
Dir2d from gp,
InteriorPoint from IntSurf
is
Value3d(myclass; PStart: InteriorPoint from IntSurf)
---Purpose: Returns the 3d coordinates of the starting point.
returns Pnt from gp;
---C++: inline
Value2d(myclass; PStart: InteriorPoint from IntSurf;
U, V: out Real from Standard);
---Purpose: Returns the <U,V> parameters which are associated
-- with <P>
-- it's the parameters which start the marching algorithm
---C++: inline
Direction3d(myclass; PStart: InteriorPoint from IntSurf)
---Purpose: returns the tangent at the intersectin in 3d space
-- associated to <P>
returns Vec from gp;
---C++: inline
Direction2d(myclass; PStart: InteriorPoint from IntSurf)
---Purpose: returns the tangent at the intersectin in the
-- parametric space of the parametrized surface.This tangent
-- is associated to the value2d
returns Dir2d from gp;
---C++: inline
