StdPrs_HLRPolyShape Class Reference

Instantiates Prs3d_PolyHLRShape to define a
display of a shape where hidden and visible lines are
identified with respect to a given projection.
StdPrs_HLRPolyShape works with a polyhedral
simplification of the shape whereas
StdPrs_HLRShape takes the shape itself into
account. When you use StdPrs_HLRShape, you
obtain an exact result, whereas, when you use
StdPrs_HLRPolyShape, you reduce computation
time but obtain polygonal segments.

Member Function Documentation

static void StdPrs_HLRPolyShape::Add ( const Handle< Prs3d_Presentation > &  aPresentation, const TopoDS_Shape &  aShape, const Handle< Prs3d_Drawer > &  aDrawer, const Handle< Prs3d_Projector > &  aProjector  )

static

 Defines the hidden line removal display of the <br>

topology aShape in the projection defined by
aProjector. The shape and the projection are added
to the display aPresentation, and the attributes of the
elements present in the aPresentation are defined by
the attribute manager aDrawer.
