Murl.Graph.ISurfaceState

The ISurfaceState graph node interface.

Surface state nodes are used to activate and/or quickly switch between physical collision surfaces (Graph::ISurface) during scene graph traversal. As soon as a specific surface is activated at a given slot via a surface state node, it stays active during traversal until a different surface state node using the same slot is encountered.

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

See sceneGraphStatesSlotsUnits for an overview of state handling during scene graph traversal.
See Graph::ISurface for defining a specific surface for handling collisions.

Murl.Graph.IStateSlot

Methods


GetNodeInterface()

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.

Murl.Graph.INode GetNodeInterface()

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

GetSurfaceNodeTarget()

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

Murl.Graph.IGenericNodeTarget.GraphISurface GetSurfaceNodeTarget()

Returns
Murl.Graph.IGenericNodeTarget.GraphISurface The mutable Graph::ISurfaceNodeTarget container, or null if not available.
