Constructs and manages a constraint by a fixed relation between two or more interactive datums. This constraint is represented by a wire from a shape - point, vertex, or edge - in the first datum and a corresponding shape in the second. Warning: This relation is not bound with any kind of parametric constraint : it represents the "status" of an parametric object. More...

virtual void	Fill (const Handle< PrsMgr_PresentationManager > &thePrsMgr, const Handle< PrsMgr_Presentation > &thePrs, const Standard_Integer theMode)
	Fills the given 3D view presentation for specified display mode using Compute() method. In addition, configures other properties of presentation (transformation, clipping planes).

virtual void	computeHLR (const Handle< Graphic3d_Camera > &theProjector, const Handle< TopLoc_Datum3D > &theTrsf, const Handle< Prs3d_Presentation > &thePrs)
	Calculates hidden line removal presentation for specific camera position. Each of the views in the viewer and every modification such as rotation, for example, entails recalculation. Default implementation throws Standard_NotImplemented exception Warning! The transformation must be applied to the object before computation.

Standard_Boolean	UpdatePresentations (Standard_Boolean theToIncludeHidden=Standard_False)
	Recomputes invalidated presentations of the object.

virtual void	SetCombinedParentTransform (const Handle< TopLoc_Datum3D > &theTrsf)
	Sets myCombinedParentTransform to theTransformation. Thus object receives transformation from parent node and able to derive its own.

virtual void	setLocalTransformation (const Handle< TopLoc_Datum3D > &theTransformation)
	Sets local transformation to theTransformation.

void	recomputeComputed () const
	Recompute computed (HLR) presentations (when view is in computed mode).

void	replaceAspects (const Graphic3d_MapOfAspectsToAspects &theMap)
	Replace aspects of existing (computed) presentation groups, so that the new aspects can be applied without recomputing presentation. It is NOT recommended approach, because user has to fill such map and then search for each occurrence in computed groups. The recommended approach is computing presentation with necessary customized aspects, and then modify them directly followed by SynchronizeAspects() call.

Detailed Description

Constructs and manages a constraint by a fixed relation between two or more interactive datums. This constraint is represented by a wire from a shape - point, vertex, or edge - in the first datum and a corresponding shape in the second. Warning: This relation is not bound with any kind of parametric constraint : it represents the "status" of an parametric object.
