//! Tool to create specific selections (sets of primitives)
|
|
//! for Shapes from Topology.
|
|
//! These Selections may be used in dynamic selection
|
|
//! Mechanism
|
|
//! Given a Shape and a mode of selection
|
|
//! (selection of vertices,
|
|
//! edges,faces ...) , This Tool Computes corresponding sensitive primitives,
|
|
//! puts them in an entity called Selection (see package SelectMgr) and returns it.
|
|
//!
|
|
//! A Priority for the decomposed pickable objects can be given ;
|
|
//! by default There is A Preset Hierachy:
|
|
//! Vertex priority : 5
|
|
//! Edge priority : 4
|
|
//! Wire priority : 3
|
|
//! Face priority : 2
|
|
//! Shell,solid,shape priority : 1
|
|
//! the default priority in the following methods has no sense - it's only taken in account
|
|
//! when the user gives a value between 0 and 10.
|
|
//! IMPORTANT : This decomposition creates BRepEntityOwner instances (from StdSelect).
|
|
//! which are stored in the Sensitive Entities coming from The Decomposition.
|
|
//!
|
|
//! the result of picking in a ViewerSelector return EntityOwner from SelectMgr;
|
|
//! to know what kind of object was picked :
|
|
//!
|
|
//! ENTITY_OWNER -> Selectable() gives the selectableobject which
|
|
//! was decomposed into pickable elements.
|
|
//! Handle(StdSelect_BRepOwner)::DownCast(ENTITY_OWNER) -> Shape()
|
|
//! gives the real picked shape (edge,vertex,shape...)
