Member Function Documentation

Add() [1/2]

static void StdPrs_ShadedShape::Add ( const Handle< Prs3d_Presentation > &  thePresentation, const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer, const Standard_Boolean  theHasTexels, const gp_Pnt2d &  theUVOrigin, const gp_Pnt2d &  theUVRepeat, const gp_Pnt2d &  theUVScale, const StdPrs_Volume  theVolume = StdPrs_Volume_Autodetection, const Handle< Graphic3d_Group > &  theGroup = NULL  )

static

Shades <theShape> with texture coordinates.

Parameters

theVolumeType

defines the way how to interpret input shapes - as Closed volumes (to activate back-face culling and capping plane algorithms), as Open volumes (shells or solids with holes) or to perform Autodetection (would split input shape into two groups)

Add() [2/2]

static void StdPrs_ShadedShape::Add ( const Handle< Prs3d_Presentation > &  thePresentation, const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer, const StdPrs_Volume  theVolume = StdPrs_Volume_Autodetection, const Handle< Graphic3d_Group > &  theGroup = NULL  )

static

Shades <theShape>.

Parameters

theVolumeType

defines the way how to interpret input shapes - as Closed volumes (to activate back-face culling and capping plane algorithms), as Open volumes (shells or solids with holes) or to perform Autodetection (would split input shape into two groups)

AddWireframeForFacesWithoutTriangles()

static void StdPrs_ShadedShape::AddWireframeForFacesWithoutTriangles ( const Handle< Prs3d_Presentation > &  thePrs, const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer  )

static

Computes special wireframe presentation for faces without triangulation.

AddWireframeForFreeElements()

static void StdPrs_ShadedShape::AddWireframeForFreeElements ( const Handle< Prs3d_Presentation > &  thePrs, const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer  )

static

Computes wireframe presentation for free wires and vertices.

ExploreSolids()

static void StdPrs_ShadedShape::ExploreSolids ( const TopoDS_Shape &  theShape, const BRep_Builder &  theBuilder, TopoDS_Compound &  theClosed, TopoDS_Compound &  theOpened, const Standard_Boolean  theIgnore1DSubShape  )

static

Searches closed and unclosed subshapes in shape structure and puts them into two compounds for separate processing of closed and unclosed sub-shapes.

FillFaceBoundaries()

static Handle< Graphic3d_ArrayOfSegments > StdPrs_ShadedShape::FillFaceBoundaries ( const TopoDS_Shape &  theShape, GeomAbs_Shape  theUpperContinuity = GeomAbs_CN  )

static

Define primitive array of boundary segments for specified shape.

Parameters

theShape	segments array or NULL if specified face does not have computed triangulation
theUpperContinuity	the most edge continuity class to be included to result (edges with more continuity will be ignored)

FillTriangles() [1/2]

static Handle< Graphic3d_ArrayOfTriangles > StdPrs_ShadedShape::FillTriangles ( const TopoDS_Shape &  theShape )

inlinestatic

Create primitive array with triangles for specified shape.

Parameters

theShape

[in] the shape with precomputed triangulation

FillTriangles() [2/2]

static Handle< Graphic3d_ArrayOfTriangles > StdPrs_ShadedShape::FillTriangles ( const TopoDS_Shape &  theShape, const Standard_Boolean  theHasTexels, const gp_Pnt2d &  theUVOrigin, const gp_Pnt2d &  theUVRepeat, const gp_Pnt2d &  theUVScale  )

static

Create primitive array of triangles for specified shape.

Parameters

theShape	the shape with precomputed triangulation
theHasTexels	define UV coordinates in primitive array
theUVOrigin	origin for UV coordinates
theUVRepeat	repeat parameters for UV coordinates
theUVScale	scale coefficients for UV coordinates

Returns

triangles array or NULL if specified face does not have computed triangulation
