Detailed Description

The IParametersState graph node interface.

Parameter state nodes are used to activate and/or quickly switch between GPU program parameters during scene graph traversal. As soon as specific parameters are activated at a given slot via a parameter state node, they stay active during traversal until a different parameter state node using the same slot is encountered.

Use the base interface's IStateSlot::SetSlot() method to set the actual slot index the referenced parameters should be attached to.

See Output-States, Slots und Units for an overview of state handling during scene graph traversal.
See Graph::IParameters for defining specific parameters for rendering.

Member Function Documentation

GetNodeInterface() [1/2]

virtual INode* Murl::Graph::IParametersState::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::IParametersState::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

GetParametersNodeTarget() [1/2]

virtual IParametersNodeTarget* Murl::Graph::IParametersState::GetParametersNodeTarget ( )

pure virtual

Get the mutable Graph::IParametersNodeTarget container.

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

Returns

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

GetParametersNodeTarget() [2/2]

virtual const IParametersNodeTarget* Murl::Graph::IParametersState::GetParametersNodeTarget ( ) const

pure virtual

Get the constant Graph::IParametersNodeTarget container.

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

Returns

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