Detailed Description

Auxiliary procedures to prepare Shaded presentation of specified shape.

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 StdPrs_Volume  theVolume = StdPrs_Volume_Autodetection 
)
static

Shades <theShape>.

Parameters
theVolumeTypedefines 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 Standard_Boolean  theHasTexels,
const gp_Pnt2d theUVOrigin,
const gp_Pnt2d theUVRepeat,
const gp_Pnt2d theUVScale,
const StdPrs_Volume  theVolume = StdPrs_Volume_Autodetection 
)
static

Shades <theShape> with texture coordinates.

Parameters
theVolumeTypedefines 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
theShapesegments array or NULL if specified face does not have computed triangulation
theUpperContinuitythe 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
theShapethe shape with precomputed triangulation
theHasTexelsdefine UV coordinates in primitive array
theUVOriginorigin for UV coordinates
theUVRepeatrepeat parameters for UV coordinates
theUVScalescale coefficients for UV coordinates
Returns
triangles array or NULL if specified face does not have computed triangulation
