## Detailed Description

Algorithm converting one shape or a set of shapes to VrmlData_Scene.

## Constructor & Destructor Documentation

VrmlData_ShapeConvert::VrmlData_ShapeConvert | ( | VrmlData_Scene & | theScene,
|  | const Standard_Real | theScale = `1.`
| ) | `[inline]`

  | Constructor. Parameters:
  | 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

## Member Function Documentation

Standard_EXPORT 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.

Standard_EXPORT void VrmlData_ShapeConvert::Convert | ( | const Standard_Boolean | theExtractFaces,
|  | const Standard_Boolean | theExtractEdges,
|  | const Standard_Real | theDeflection = `0.01`,
|  | const Standard_Real | theDeflAngle = `20.*PI/180.`
| ) |

  | Convert all accumulated shapes and store them in myScene. The internal data structures are cleared in the end of convertion. Parameters:
  | 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.
