Algorithm converting one shape or a set of shapes to VrmlData_Scene.
VrmlData_ShapeConvert::VrmlData_ShapeConvert | ( | VrmlData_Scene & | theScene, |
const Standard_Real | theScale = 1. |
||
) | [inline] |
Constructor.
theScene | Scene receiving all Vrml data. |
theScale | Scale factor, considering that VRML standard specifies coordinates in meters. So if your data are in mm, you should provide theScale=0.001 |
void VrmlData_ShapeConvert::AddShape | ( | const TopoDS_Shape & | theShape, |
const char * | theName = 0L |
||
) |
Add one shape to the internal list, may be called several times with different shapes.
void VrmlData_ShapeConvert::Convert | ( | const Standard_Boolean | theExtractFaces, |
const Standard_Boolean | theExtractEdges, | ||
const Standard_Real | theDeflection = 0.01 , |
||
const Standard_Real | theDeflAngle = 20.*M_PI/180. |
||
) |
Convert all accumulated shapes and store them in myScene. The internal data structures are cleared in the end of convertion.
theExtractFaces | If True, converter extracst faces from the shapes. |
theExtractEdges | If True, converter extracts edges from the shapes. |
theDeflection | Deflection for tessellation of geometrical lines/surfaces. Existing mesh is used if its deflection is smaller than the one given by this parameter. |
theDeflAngle | Angular deflection for tessellation of geometrical lines. |
