Create a selectable trihedron
there are 4 modes of selection :
mode = 0 to select triedron ,priority = 1
mode = 1 to select its origine ,priority = 5
mode = 2 to select its axis ,priority = 3
mode = 3 to select its planes ,priority = 2
a trihedron has 1 origine,3 axes,3 planes.
Warning
For the presentation of trihedra, 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 trihedra, this is
AIS_Drawer_FirstAxisAspect. You change the
values inside this Aspect and recalculate the presentation.
If you want to use extended selection modes, different than 0,
you should take care of removing of the shapes from the interactive
context that has been computed for selection; it might be necessary
when you change selection mode. You can use methods Axis, Point,
Plane to retrieve the shapes.

	Sets up polygon offsets for this object. <br> It modifies all existing presentations of <anObj> (if any), <br> so it is reasonable to call this method after <anObj> has been displayed. <br> Otherwise, Compute() method should pass Graphic3d_AspectFillArea3d <br> aspect from <myDrawer> to Graphic3d_Group to make polygon offsets work. <br> <aMode> parameter can contain various combinations of Aspect_PolygonOffsetMode enumeration elements (Aspect_POM_None means that polygon offsets are not changed). If <aMode> is different from Aspect_POM_Off and Aspect_POM_None, then <aFactor> and <aUnits> arguments are used by graphic renderer to calculate a depth offset value: offset = <aFactor> * m + <aUnits> * r, where m - maximum depth slope for the polygon currently being displayed, r - minimum window coordinates depth resolution (implementation-specific). Deafult settings for OCC 3D viewer: mode = Aspect_POM_Fill, factor = 1., units = 0. Negative offset values move polygons closer to the viewport, while positive values shift polygons away. Consult OpenGL reference for details (glPolygonOffset function description). NOTE: This method has a side effect - it creates own shading aspect if not yet created, so it is better to set up object material, color, etc. first. More...

Detailed Description

Create a selectable trihedron
there are 4 modes of selection :
mode = 0 to select triedron ,priority = 1
mode = 1 to select its origine ,priority = 5
mode = 2 to select its axis ,priority = 3
mode = 3 to select its planes ,priority = 2
a trihedron has 1 origine,3 axes,3 planes.
Warning
For the presentation of trihedra, 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 trihedra, this is
AIS_Drawer_FirstAxisAspect. You change the
values inside this Aspect and recalculate the presentation.
If you want to use extended selection modes, different than 0,
you should take care of removing of the shapes from the interactive
context that has been computed for selection; it might be necessary
when you change selection mode. You can use methods Axis, Point,
Plane to retrieve the shapes.

virtual

only the interactive obj knowns which Drawer attribute
is affected by the color (ex: for a wire, it's the
wireaspect field of the drawer, but for a vertex, only
the point aspect field is affected by the color)
WARNING : Do not forget to set the corresponding fields
here (hasOwnColor and myOwnColor)

Reimplemented from AIS_InteractiveObject.
