TopTrans_SurfaceTransition Class Reference

This algorithm is used to compute the transition of a 3D surface intersecting a topological surfacic boundary on a 3D curve ( intersection curve ). The boundary is described by a set of faces each face is described by. More...

Detailed Description

This algorithm is used to compute the transition of a 3D surface intersecting a topological surfacic boundary on a 3D curve ( intersection curve ). The boundary is described by a set of faces each face is described by.

◆ Compare() [1/2]

void TopTrans_SurfaceTransition::Compare ( const Standard_Real  Tole,
const gp_Dir Norm,
const gp_Dir MaxD,
const gp_Dir MinD,
const Standard_Real  MaxCurv,
const Standard_Real  MinCurv,
const TopAbs_Orientation  S,
const TopAbs_Orientation  O 
)

Add a face element to the boundary.

  • S defines topological orientation for the face : S FORWARD means: along the intersection curve on the reference surface, transition states while crossing the face are OUT,IN. S REVERSED means states are IN,OUT. S INTERNAL means states are IN,IN.
  • O defines curve's position on face : O FORWARD means the face is before the intersection O REVERSED means the face is AFTER O INTERNAL means the curve intersection is in the face. PREQUESITORY : Norm oriented OUTSIDE "geometric matter"

◆ Compare() [2/2]

void TopTrans_SurfaceTransition::Compare ( const Standard_Real  Tole,
const gp_Dir Norm,
const TopAbs_Orientation  S,
const TopAbs_Orientation  O 
)

Add a plane or a cylindric face to the boundary.

◆ GetAfter()

◆ Reset() [1/2]

void TopTrans_SurfaceTransition::Reset ( const gp_Dir Tgt,
const gp_Dir Norm 
)

Initialize a Surface Transition with the local description of a straight line.

◆ Reset() [2/2]

void TopTrans_SurfaceTransition::Reset ( const gp_Dir Tgt,
const gp_Dir Norm,
const gp_Dir MaxD,
const gp_Dir MinD,
const Standard_Real  MaxCurv,
const Standard_Real  MinCurv 
)

Initialize a Surface Transition with the local description of the intersection curve and of the reference surface. PREQUESITORY : Norm oriented OUTSIDE "geometric matter".

◆ StateAfter()

TopAbs_State TopTrans_SurfaceTransition::StateAfter ( ) const

Returns the state of the reference surface after interference, this is the position relative to the surface of a point very close to the intersection on the positive side of the tangent.

◆ StateBefore()

TopAbs_State TopTrans_SurfaceTransition::StateBefore ( ) const

Returns the state of the reference surface before the interference, this is the position relative to the surface of a point very close to the intersection on the negative side of the tangent.
