Detailed Description

Inherited from InternalAlgo to provide methods with Shape from TopoDS. A framework to compute a shape as seen in a projection plane. This is done by calculating the visible and the hidden parts of the shape. HLRBRep_Algo works with three types of entity:

Constructor & Destructor Documentation

◆ HLRBRep_Algo() [1/2]

HLRBRep_Algo::HLRBRep_Algo ( )

Constructs an empty framework for the calculation of visible and hidden lines of a shape in a projection. Use the function:

  • Projector to define the point of view
  • Add to select the shape or shapes to be visualized
  • Update to compute the outlines of the shape, and
  • Hide to compute the visible and hidden lines of the shape.

◆ HLRBRep_Algo() [2/2]

HLRBRep_Algo::HLRBRep_Algo ( const Handle< HLRBRep_Algo > &  A)

Member Function Documentation

◆ Add() [1/2]

void HLRBRep_Algo::Add ( const TopoDS_Shape S,
const Handle< Standard_Transient > &  SData,
const Standard_Integer  nbIso = 0 
)

add the Shape <S>.

◆ Add() [2/2]

void HLRBRep_Algo::Add ( const TopoDS_Shape S,
const Standard_Integer  nbIso = 0 
)

Adds the shape S to this framework, and specifies the number of isoparameters nbiso desired in visualizing S. You may add as many shapes as you wish. Use the function Add once for each shape.

◆ Index()

Standard_Integer HLRBRep_Algo::Index ( const TopoDS_Shape S)

return the index of the Shape <S> and return 0 if the Shape <S> is not found.

◆ OutLinedShapeNullify()

void HLRBRep_Algo::OutLinedShapeNullify ( )

nullify all the results of OutLiner from HLRTopoBRep.
