Detailed Description

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

Constructor & Destructor Documentation

VrmlData_ShapeConvert()

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

addAssembly()

void VrmlData_ShapeConvert::addAssembly ( const Handle< VrmlData_Group > &  theParent, const TDF_Label &  theLabel, const Handle< TDocStd_Document > &  theDoc, const Standard_Boolean  theNeedCreateGroup  )

protected

addInstance()

void VrmlData_ShapeConvert::addInstance ( const Handle< VrmlData_Group > &  theParent, const TDF_Label &  theLabel, const Handle< TDocStd_Document > &  theDoc  )

protected

AddShape()

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.

addShape()

void VrmlData_ShapeConvert::addShape ( const Handle< VrmlData_Group > &  theParent, const TDF_Label &  theLabel, const Handle< TDocStd_Document > &  theDoc  )

Convert()

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.

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.

ConvertDocument()

void VrmlData_ShapeConvert::ConvertDocument

(

const Handle< TDocStd_Document > &

theDoc

)

Add all shapes start from given document with colors and names to the internal structure
