Detailed Description

The IListenerState graph node interface.

Listener state nodes are used to activate and/or quickly switch between listeners during scene graph traversal. As soon as a specific listener is activated via a listener state node, it stays active during traversal until a different listener state node is encountered.

See Output-States, Slots und Units for an overview of state handling during scene graph traversal.
See Graph::IListener for defining a specific listener for rendering.
See Graph::IListenerTransform for setting a listener's position and orientation.

Member Function Documentation

GetNodeInterface() [1/2]

virtual INode* Murl::Graph::IListenerState::GetNodeInterface ( )

pure virtual

Get the mutable Graph::INode interface.

This method returns a mutable pointer to the node's Graph::INode interface, to be able to query or modify common node properties such as active state, visibility or ID.

Returns

The mutable Graph::INode interface, or null if not available

GetNodeInterface() [2/2]

virtual const INode* Murl::Graph::IListenerState::GetNodeInterface ( ) const

pure virtual

Get the constant Graph::INode interface.

This method returns a constant pointer to the node's Graph::INode interface, to be able to query common node properties such as active state, visibility or ID.

Returns

The constant Graph::INode interface, or null if not available

GetListenerNodeTarget() [1/2]

virtual IListenerNodeTarget* Murl::Graph::IListenerState::GetListenerNodeTarget ( )

pure virtual

Get the mutable Graph::IListenerNodeTarget container.

This method returns a mutable pointer to the node's Graph::IListenerNodeTarget container, which allows to set or query the listener this state node refers to.

Returns

The mutable Graph::IListenerNodeTarget container, or null if not available.

GetListenerNodeTarget() [2/2]

virtual const IListenerNodeTarget* Murl::Graph::IListenerState::GetListenerNodeTarget ( ) const

pure virtual

Get the constant Graph::IListenerNodeTarget container.

This method returns a constant pointer to the node's Graph::IListenerNodeTarget container, which allows to query the listener this state node refers to.

Returns

The mutable Graph::IListenerNodeTarget container, or null if not available.
