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.
