Constructor & Destructor Documentation

Prs3d_Projector::Prs3d_Projector ( const HLRAlgo_Projector Pr)
Prs3d_Projector::Prs3d_Projector ( const Standard_Boolean  Pers,
const Quantity_Length  Focus,
const Quantity_Length  DX,
const Quantity_Length  DY,
const Quantity_Length  DZ,
const Quantity_Length  XAt,
const Quantity_Length  YAt,
const Quantity_Length  ZAt,
const Quantity_Length  XUp,
const Quantity_Length  YUp,
const Quantity_Length  ZUp 
)

Constructs a projector framework from the following parameters.

  • Pers is true if the view is a perspective view and false if it is an axonometric one;
  • Focus is the focal length if a perspective view is defined;
  • DX, DY and DZ are the coordinates of the projection vector;
  • XAt, YAt and ZAt are the coordinates of the view point;
  • XUp, YUp and ZUp are the coordinates of the vertical direction vector.
