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.
