A framework to define finding, sorting the sensitive primitives in a view. Services are also provided to define the return of the owners of those primitives selected. The primitives are sorted by criteria such as priority of the primitive or its depth in the view relative to that of other primitives. Note that in 3D, the inheriting framework StdSelect_ViewerSelector3d is only to be used if you do not want to use the services provided by AIS. Two tools are available to find and select objects found at a given position in the view. If you want to select the owners of all the objects detected at point x,y,z you use the Init - More - Next - Picked loop. If, on the other hand, you want to select only one object detected at that point, you use the Init - More - OnePicked loop. In this iteration, More is used to see if an object was picked and OnePicked, to get the object closest to the pick position. Viewer selectors are driven by SelectMgr_SelectionManager, and manipulate the SelectMgr_Selection objects given to them by the selection manager. More...

Detailed Description

A framework to define finding, sorting the sensitive primitives in a view. Services are also provided to define the return of the owners of those primitives selected. The primitives are sorted by criteria such as priority of the primitive or its depth in the view relative to that of other primitives. Note that in 3D, the inheriting framework StdSelect_ViewerSelector3d is only to be used if you do not want to use the services provided by AIS. Two tools are available to find and select objects found at a given position in the view. If you want to select the owners of all the objects detected at point x,y,z you use the Init - More - Next - Picked loop. If, on the other hand, you want to select only one object detected at that point, you use the Init - More - OnePicked loop. In this iteration, More is used to see if an object was picked and OnePicked, to get the object closest to the pick position. Viewer selectors are driven by SelectMgr_SelectionManager, and manipulate the SelectMgr_Selection objects given to them by the selection manager.

Tolerances are applied to the entities in the following way:

tolerance value stored in mytolerance will be used to calculate initial selecting frustum, which will be applied for intersection testing during BVH traverse;
if tolerance of sensitive entity is less than mytolerance, the frustum for intersection detection will be resized according to its sensitivity.
