class ContextPick from Visual3d
|
||
|
||
---Version:
|
||
|
||
---Purpose: This class allows the creation and update of
|
||
-- a pick context for one view of the viewer.
|
||
-- A context allows the control of different parameters
|
||
-- before the activation of a pick.
|
||
--
|
||
-- * the pick aperture.
|
||
-- * the depth of pick, the number of sub-structures selected.
|
||
-- * the order of picking, the possibility to traverse
|
||
-- the pick structures starting from the root
|
||
-- or the leaves.
