Detailed Description

Instance required for using Transitions.

The TransitionInstance is used with Transition to select between a set of geoms. A transition from one geom to another is made by specifying a new level for the instance. A smooth blend from the old geom to the new geom is performed using parameters from the transition.

Constructor & Destructor Documentation

Q::TransitionInstance::TransitionInstance (   )  [inline]

Create a null transition instance reference.

Q::TransitionInstance::TransitionInstance (  const char *   )

Search the currently attached databases for a transition instance with the given name.

Member Function Documentation

TransitionInstance Q::TransitionInstance::cast (  const ObjectBase &   )  [static]

If the object referenced by obj is a transition instance, then return a suitable TransitionInstance reference to the object. Note: Casting this object will cause it to be loaded from the database if it is not currently resident. Reimplemented from Q::Instance.

ClassType Q::TransitionInstance::classType (   )  [static]

Return the type for this class. Reimplemented from Q::Instance.

TransitionInstance Q::TransitionInstance::create (  const char *  name, const Transition &  trans, const Group &  group, const Database &  db = Database() )  [static]

Create a new transition instance named name in the given database, db, (or the most recently attached read-write database if db is null). The transition trans is bound into the scene graph at location group.

TransitionInstance Q::TransitionInstance::find (  const char *  name  )  [static]

Search the currently attached databases for a transition instance with the given name and return that object, if it exists. Reimplemented from Q::Instance.

unsigned int Q::TransitionInstance::level (   )  const

Return the current level number for this transition instance.

Utils::Result Q::TransitionInstance::setLevel (  unsigned int  l  )

Set the level number for this transition instance, triggering a transition blend if necessary.
