		const Quantity_Length	OffSet
	)

Sets the location and the size of the grid. <XSize> defines the width of the grid. <YSize> defines the height of the grid. <OffSet> defines the displacement along the plane normal.

void V3d_Viewer::SetRectangularGridValues	(	const Quantity_Length	XOrigin,
		const Quantity_Length	YOrigin,
		const Quantity_Length	XStep,
		const Quantity_Length	YStep,
		const Quantity_PlaneAngle	RotationAngle
	)

Sets the definition of the rectangular grid. <XOrigin>, <YOrigin> defines the origin of the grid. <XStep> defines the interval between 2 vertical lines. <YStep> defines the interval between 2 horizontal lines. <RotationAngle> defines the rotation angle of the grid.

void V3d_Viewer::SetUpdateMode ( const V3d_TypeOfUpdate Mode )

Defines the mode of regenerating the views making up the viewer. This can be immediate <ASAP> or deferred <WAIT>. In this latter case, the views are updated when the method Update(me) is called.

void V3d_Viewer::SetViewOff ( )

Deactivates all the views of a Viewer attached to a window.

void V3d_Viewer::SetViewOff ( const Handle< V3d_View > & View )

Deactivates a particular view in the Viewer. Must be call if the Window attached to the view has been Iconified .

void V3d_Viewer::SetViewOn ( )

Activates all of the views of a viewer attached to a window.

void V3d_Viewer::SetViewOn ( const Handle< V3d_View > & View )

Activates a particular view in the Viewer . Must be call if the Window attached to the view has been Deiconified .

void V3d_Viewer::SetZBufferManagment ( const Standard_Boolean Automatic )

defines the strategy concerning the ZBuffer activity. If Automatic is true, ZBuffer will be activated or deactivated depending on the fact that faces exist or not in the Viewer. This will optimize the response time in the case where only wireframe objects are displayed. If Automatic is False, ZBuffer will be activated or deactivated depending on the choice of SetVisualization in each View. Note that by default, the ZBufferManagment is not automatic.

void V3d_Viewer::SetZLayerSettings	(	const Standard_Integer	theLayerId,
		const Graphic3d_ZLayerSettings &	theSettings
	)

Sets the settings for a single Z layer.

void V3d_Viewer::ShowGridEcho	(	const Handle< V3d_View > &	theView,
		const Graphic3d_Vertex &	thePoint
	)

Display grid echo at requested point in the view.

void V3d_Viewer::UnHighlight ( ) const

UnHighlight all Objects in All the views.

void V3d_Viewer::Update ( )

Deprecated, Redraw() should be used instead.

void V3d_Viewer::UpdateLights ( )

Updates the lights of all the views of a viewer.

V3d_TypeOfUpdate V3d_Viewer::UpdateMode ( ) const

Returns the regeneration mode of views in the viewer.

Handle< Visual3d_ViewManager > V3d_Viewer::Viewer ( ) const

Returns the viewer associated to Visual3d .

Standard_Boolean V3d_Viewer::ZBufferManagment ( ) const

returns the ZBuffer stategy choice.

Graphic3d_ZLayerSettings V3d_Viewer::ZLayerSettings ( const Standard_Integer theLayerId )

Returns the settings of a single Z layer.
