Detailed Description

The ILightState graph node interface.

Light state nodes are used to activate lights for rendering during scene graph traversal. As soon as a specific light is activated via a light state node, it stays active during traversal until a different light state node is encountered.

See Output-States, Slots und Units for an overview of state handling during scene graph traversal.
See Graph::ILight for defining individual light sources and their group assignment.
See Graph::ILightTransform for setting a light's position and orientation.

Member Function Documentation

GetNodeInterface() [1/2]

virtual INode* Murl::Graph::ILightState::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::ILightState::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

GetLightNodeTarget() [1/2]

virtual ILightNodeTarget* Murl::Graph::ILightState::GetLightNodeTarget ( )

pure virtual

Get the mutable Graph::ILightNodeTarget container.

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

Returns

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

GetLightNodeTarget() [2/2]

virtual const ILightNodeTarget* Murl::Graph::ILightState::GetLightNodeTarget ( ) const

pure virtual

Get the constant Graph::ILightNodeTarget container.

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

Returns

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