	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.

bool	UpdatePresentations (bool theToIncludeHidden=false)
	Recomputes invalidated presentations of the object.

virtual void	SetCombinedParentTransform (const occ::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 occ::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 NCollection_DataMap< occ::handle< Graphic3d_Aspects >, occ::handle< Graphic3d_Aspects > > &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

Create a selectable trihedron The trihedron includes 1 origin, 3 axes and 3 labels. Default text of labels are "X", "Y", "Z". Color of origin and any axis, color of arrows and labels may be changed. Visual presentation might be shown in two, shaded and wireframe modes, wireframe by default). There are 4 modes of selection:

AIS_TrihedronSelectionMode_EntireObject to select trihedron, priority = 1
AIS_TrihedronSelectionMode_Origin to select its origin, priority = 5
AIS_TrihedronSelectionMode_Axes to select its axis, priority = 3
AIS_TrihedronSelectionMode_MainPlanes to select its planes, priority = 2

Warning! For the presentation of trihedron, the default unit of length is the millimetre, and the default value for the representation of the axes is 100. If you modify these dimensions, you must temporarily recover the Drawer. From inside it, you take the aspect in which the values for length are stocked. For trihedron, this is Prs3d_Drawer_LineAspect. You change the values inside this Aspect and recalculate the presentation.
