The Interactive Context allows you to manage
graphic behavior and selection of Interactive Objects
in one or more viewers. Class methods make this
highly transparent.
It is essential to remember that an Interactive Object
which is already known by the Interactive Context
must be modified using Context methods. You can
only directly call the methods available for an
Interactive Object if it has not been loaded into an
Interactive Context.
You must distinguish two states in the Interactive Context:

void	Display (const Handle< AIS_InteractiveObject > &anIobj, const Standard_Boolean updateviewer=Standard_True)
	Controls the choice between the using the display <br> and selection modes of open local context which you have defined and activating those available by default. If a local context is open and if updateviewer equals Standard_False, the Interactive Object anIobj is displayed in the default active mode. This will be the object's default display mode, if there is one. Otherwise, it will be the context mode. The Interactive Object's default selection mode is activated. In general, this is 0. This syntax has the same behavior as local context, open or closed. If you want to view the object in open local context without selection, use the syntax below, setting aSelectionMode to -1. More...

void	Display (const Handle< AIS_InteractiveObject > &anIobj, const Standard_Integer amode, const Standard_Integer aSelectionMode, const Standard_Boolean updateviewer=Standard_True, const Standard_Boolean allowdecomposition=Standard_True)
	Controls the choice between the using the display <br> and selection modes of open local context which you have defined and activating those available by default. If no Local Context is opened. and the Interactive Object aniobj has no display mode of its own, the default display mode, 0, is used. Likewise, if aniobj has no selection mode of its own, the default one, 0, is used. If a local context is open and if updateviewer equals Standard_False, the presentation of the Interactive Object activates the selection mode; the object is displayed but no viewer will be updated. If aSelectionMode equals -1, anIobj will not be activated: it will be displayed but will not be selectable. Use this if you want to view the object in open local context without selection. Note: This option is only available in Local Context. If allowDecomposition equals true, anIObj can have subshapes detected by selection mechanisms. anIObj must be able to give a shape selection modes which fit the AIS_Shape selection modes: More...

Detailed Description

The Interactive Context allows you to manage
graphic behavior and selection of Interactive Objects
in one or more viewers. Class methods make this
highly transparent.
It is essential to remember that an Interactive Object
which is already known by the Interactive Context
must be modified using Context methods. You can
only directly call the methods available for an
Interactive Object if it has not been loaded into an
Interactive Context.
You must distinguish two states in the Interactive Context:

No Open Local Context, also known as the Neutral Point.
One or several open local contexts, each
representing a temporary state of selection and presentation.
Some methods can only be used in open Local
Context; others in closed Local Context; others do
not have the same behavior in one state as in the other.
The possiblities of use for local contexts are
numerous depending on the type of operation that
you want to perform, for example:
working on all visualized interactive objects,
working on only a few objects,
working on a single object.
1. When you want ot work on one type of entity, you
  should open a local context with the option
  UseDisplayedObjects set to false. DisplayedObjects
  allows you to recover the visualized Interactive
  Objects which have a given Type and
  Signature from Neutral Point.

You must keep in mind the fact that when you open
a Local Context with default options:

The Interactive Objects visualized at Neutral Point
are activated with their default selection mode. You
must deactivate those which you do not want ot use.
The Shape type Interactive Objects are
automatically decomposed into sub-shapes when
standard activation modes are launched.
The "temporary" Interactive Objects present in the
Local Contexts are not automatically taken into
account. You have to load them manually if you
want to use them.
The stages could be the following:
- Open a Local Context with the right options;
- Load/Visualize the required complementary
  objects with the desired activation modes.
- Activate Standard modes if necessary
Create its filters and add them to the Local Context
- Detect/Select/recover the desired entities
- Close the Local Context with the adequate index.
It is useful to create an interactive editor, to which
you pass the Interactive Context. This will take care
of setting up the different contexts of
selection/presentation according to the operation
which you want to perform.

aStandardActivation for all objects in Local Context
which accept decomposition into sub-shapes.
Every new Object which has been loaded into the
interactive context and which answers these
decomposition criteria is automatically activated
according to these modes.
Warning
If you have opened a local context by loading an
object with the default options
(<AllowShapeDecomposition>= Standard_True), all
objects of the "Shape" type are also activated with
the same modes. You can act on the state of these
"Standard" objects by using SetShapeDecomposition(Status).

void AIS_InteractiveContext::AddFilter ( const Handle< SelectMgr_Filter > & aFilter )

void AIS_InteractiveContext::ClearActiveSensitive ( const Handle< V3d_View > & aView )

void AIS_InteractiveContext::ClearCurrents ( const Standard_Boolean updateviewer = Standard_True )

Empties previous current objects in order to get the
current objects detected by the selector using
UpdateCurrent.
Objects selected when there is no open local context
are called current objects; those selected in open
local context, selected objects.

return to Neutral Point.
If a local context is open and if updateviewer equals
Standard_False, the presentation of the Interactive
Object activates the selection mode; the object is
displayed but no viewer will be updated.

void AIS_InteractiveContext::CloseLocalContext	(	const Standard_Integer	Index = `-1`,
		const Standard_Boolean	updateviewer = `Standard_True`
	)

 Allows you to close local contexts. For greater <br>

security, you should close the context with the
index Index given on opening.
When you close a local context, the one before,
which is still on the stack, reactivates. If none is
left, you return to Neutral Point.
If a local context is open and if updateviewer
equals Standard_False, the presentation of the
Interactive Object activates the selection mode; the
object is displayed but no viewer will be updated.
Warning
When the index isn't specified, the current context
is closed. This option can be dangerous, as other
Interactive Functions can open local contexts
without necessarily warning the user.

Standard_Real AIS_InteractiveContext::DeviationAngle ( ) const

Standard_Real AIS_InteractiveContext::DeviationCoefficient ( ) const

 Returns the deviation coefficient. <br>

Drawings of curves or patches are made with respect
to a maximal chordal deviation. A Deviation coefficient
is used in the shading display mode. The shape is
seen decomposed into triangles. These are used to
calculate reflection of light from the surface of the
object. The triangles are formed from chords of the
curves in the shape. The deviation coefficient gives
the highest value of the angle with which a chord can
deviate from a tangent to a curve. If this limit is
reached, a new triangle is begun.
This deviation is absolute and is set through
AIS_Drawer::SetMaximalChordialDeviation. The
default value is 0.001.
In drawing shapes, however, you are allowed to ask
for a relative deviation. This deviation will be:
SizeOfObject * DeviationCoefficient.

and selection modes of open local context which you
have defined and activating those available by default.
If a local context is open and if updateviewer equals
Standard_False, the Interactive Object anIobj is
displayed in the default active mode. This will be the
object's default display mode, if there is one.
Otherwise, it will be the context mode. The Interactive
Object's default selection mode is activated. In
general, this is 0.
This syntax has the same behavior as local context,
open or closed. If you want to view the object in open
local context without selection, use the syntax below,
setting aSelectionMode to -1.

void AIS_InteractiveContext::Display	(	const Handle< AIS_InteractiveObject > &	anIobj,
		const Standard_Integer	amode,

and selection modes of open local context which you
have defined and activating those available by default.
If no Local Context is opened. and the Interactive
Object aniobj has no display mode of its own, the
default display mode, 0, is used. Likewise, if aniobj
has no selection mode of its own, the default one, 0, is used.
If a local context is open and if updateviewer equals
Standard_False, the presentation of the Interactive
Object activates the selection mode; the object is
displayed but no viewer will be updated.
If aSelectionMode equals -1, anIobj will not be
activated: it will be displayed but will not be selectable.
Use this if you want to view the object in open local
context without selection. Note: This option is only
available in Local Context.
If allowDecomposition equals true, anIObj can have
subshapes detected by selection mechanisms. anIObj
must be able to give a shape selection modes which
fit the AIS_Shape selection modes:

vertices: 1
edges: 2
wires: 3.

the shape. The deviation coefficient give the highest
value of the angle with which a chord can deviate
from a tangent to a curve. If this limit is reached, a
new triangle is begun.
To find the hidden lines, hidden line display mode
entails recalculation of the view at each different
projector perspective.
Because hidden lines entail calculations of more than
usual complexity to decompose them into these
triangles, a deviation coefficient allowing greater
tolerance is used. This increases efficiency in calculation.
