static Standard_Boolean StdPrs_ToolTriangulatedShape::IsClosed ( const TopoDS_Shape &  theShape )

static

Checks back faces visibility for specified shape (to activate back-face culling).

Returns

true if shape is closed manifold Solid or compound of such Solids.

static Standard_Boolean StdPrs_ToolTriangulatedShape::IsTessellated ( const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer  )

static

Checks whether the shape is properly triangulated for a given display settings.

Parameters

theShape	[in] the shape.
theDrawer	[in] the display settings.

static Standard_Boolean StdPrs_ToolTriangulatedShape::IsTriangulated ( const TopoDS_Shape &  theShape )

static

Similar to BRepTools::Triangulation() but without extra checks.

Returns

true if all faces within shape are triangulated.

static void StdPrs_ToolTriangulatedShape::Normal ( const TopoDS_Face &  theFace, Poly_Connect &  thePolyConnect, TColgp_Array1OfDir &  theNormals  )

static

Evaluate normals for a triangle of a face.

Parameters

theFace	[in] the face.
thePolyConnect	[in] the definition of a face triangulation.
theNormal	[out] the array of normals for each triangle.

static Standard_Boolean StdPrs_ToolTriangulatedShape::Tessellate ( const TopoDS_Shape &  theShape, const Handle< Prs3d_Drawer > &  theDrawer  )

static

Validates triangulation within the shape and performs tessellation if necessary.

Parameters

theShape	[in] the shape.
theDrawer	[in] the display settings.

Returns

true if tesselation was recomputed and false otherwise.
