Methods
  NameDescription
Public methodApply(SoNode)

Initiates an action on the graph defined by a node.

(Overrides SoActionApply(SoNode).)
Public methodApply(SoPath)

Initiates an action on the graph defined by a path.

(Overrides SoActionApply(SoPath).)
Public methodApply(SoPathList)
Calls Apply(pathList, false).
Public methodApply(SoPathList, Boolean)

Initiates an action on the graph defined by a list of paths.

(Overrides SoActionApply(SoPathList, Boolean).)
Public methodClearApplyResult

When applied, an action may reference nodes or create objects (e.g.

(Inherited from SoAction.)
Public methodStatic memberEnableElement
Public methodEnableElements Obsolete.
Returns the list of enabled elements for a given action subclass.
(Inherited from SoAction.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodForwardTraversal(SoNode)

Traverse a node that is not part of the current scenegraph.

(Inherited from SoAction.)
Public methodForwardTraversal(SoPath)

Traverse a path that is not part of the current scenegraph.

(Inherited from SoAction.)
Public methodGetContinueActionInBranchFlag

This function indicates if the action must stop in the current branch.

(Inherited from SoAction.)
Public methodGetCurPath

Returns the path accumulated during traversal, i.e., the chain of nodes from the root of the traversed graph to the current node being traversed.

(Inherited from SoAction.)
Public methodGetDistribMode

Returns the distribution mode of this action across a cluster (ScaleViz-Cluster only).

(Inherited from SoAction.)
Public methodGetHashCode
Overrides GetHashCode().
(Inherited from SoNetBase.)
Public methodStatic memberGetIntersectEpsilon

Queries epsilon (small value) to be used in the collision computation.

Public methodGetNodeAppliedTo

Returns the node the action is being applied to.

(Inherited from SoAction.)
Public methodGetOriginalPathListAppliedTo

Returns the original path list the action is being applied to.

(Inherited from SoAction.)
Public methodGetPathAppliedTo

Returns the path the action is being applied to.

(Inherited from SoAction.)
Public methodGetPathCode

Returns path code based on where current node (the node at the end of the current path) lies with respect to the path(s) the action is being applied to.

(Inherited from SoAction.)
Public methodGetPathListAppliedTo

Returns the path list the action is being applied to.

(Inherited from SoAction.)
Public methodGetPipeId

Gets pipe identifier in the range [1..N] associated to this render action while running a ScaleViz Multipipe configuration.

(Inherited from SoAction.)
Public methodGetSceneManager

Return the OIV.Inventor.SoSceneManager associated with this action.

(Inherited from SoAction.)
Public methodGetState

Gets the state from the action.

(Inherited from SoAction.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodGetWhatAppliedTo

Returns code indicating what action is being applied to.

(Inherited from SoAction.)
Public methodHasTerminated

Returns true if the traversal has reached a termination condition.

(Inherited from SoAction.)
Public methodInvalidateState

Invalidates the current traversal state in the action, forcing it to be recreated when the action is next applied.

(Inherited from SoAction.)
Public methodIsBeingApplied

Returns true if this action is currently being applied.

(Inherited from SoAction.)
Public methodIsLastPathListAppliedTo

Returns true if the current list is the last one from the original.

(Inherited from SoAction.)
Public methodIsUsingAlternateRep

Returns true if current action is using alternate representations.

(Inherited from SoAction.)
Public methodPostDelayedTraversal

Method called by SoMultiPassManager after delayed pass traversals.

(Inherited from SoAction.)
Public methodPreDelayedTraversal

Method called by SoMultiPassManager before delayed pass traversals.

(Inherited from SoAction.)
Public methodResetContinueActionInBranchFlag

This function resets the continue action flag.

(Inherited from SoAction.)
Public methodStatic memberSetIntersectEpsilon

Sets epsilon (small value) to be used in the collision computation.

Public methodSetPipeId

Sets pipe identifier in the range [1..N] associated to this render action while running a ScaleViz Multipipe configuration.

(Inherited from SoAction.)
Public methodSetSceneManager

Set the scene manager associated with this action (if any ).

(Inherited from SoAction.)
Public methodSetUpState

Creates state if it is NULL or it is no longer valid because new elements have been enabled since it was created.

(Inherited from SoAction.)
Public methodStopActionInBranch

This function stops the action in the current Scene Graph branch.

(Inherited from SoAction.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodTraverse

Does traversal of a graph rooted by a node.

(Inherited from SoAction.)
Public methodUseAlternateRep

Tell the action to use alternate representations during traversal when available.

(Inherited from SoAction.)

Remarks

This action allows the programmer to analyze a scene graph to know which pairs of objects within the scene intersect.

The action first detects intersections between pairs of bounding boxes. If such an intersection occurs, the programmer can abort the action or allow it to determine if the primitives of the objects actually collide.

The algorithm can call programmer-supplied delegates when there is an intersection between two objects.
