SyntaxThe SoIntersectionDetectionAction type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoIntersectionDetectionAction | Constructor. |
Methods| Name | Description | |
|---|---|---|
| Apply(SoNode) | Initiates an action on the graph defined by a node. |
| Apply(SoPath) | Initiates an action on the graph defined by a path. |
| Apply(SoPathList) | Calls Apply(pathList, false). |
| Apply(SoPathList, Boolean) | Initiates an action on the graph defined by a list of paths. |
| ClearApplyResult | When applied, an action may reference nodes or create objects (e.g. |
 | EnableElement | |
| EnableElements | (Overrides SoActionEnableElements.) |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| ForwardTraversal(SoNode) | Traverse a node that is not part of the current scenegraph. |
| ForwardTraversal(SoPath) | Traverse a path that is not part of the current scenegraph. |
| GetContinueActionInBranchFlag | This function indicates if the action must stop in the current branch. |
| GetCurPath | 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. |
| GetDistribMode | Returns the distribution mode of this action across a cluster (ScaleViz-Cluster only). |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetIntersectEpsilon | Queries epsilon (small value) to be used in the collision computation. |
| GetNodeAppliedTo | Returns the node the action is being applied to. |
| GetOriginalPathListAppliedTo | Returns the original path list the action is being applied to. |
| GetPathAppliedTo | Returns the path the action is being applied to. |
| GetPathCode | 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. |
| GetPathListAppliedTo | Returns the path list the action is being applied to. |
| GetPipeId | Gets pipe identifier in the range [1..N] associated to this render action while running a ScaleViz Multipipe configuration. |
| GetSceneManager | Return the OIV.Inventor.SoSceneManager associated with this action. |
| GetState | Gets the state from the action. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetWhatAppliedTo | Returns code indicating what action is being applied to. |
| HasTerminated | Returns true if the traversal has reached a termination condition. |
| InvalidateState | Invalidates the current traversal state in the action, forcing it to be recreated when the action is next applied. |
| IsBeingApplied | Returns true if this action is currently being applied. |
| IsLastPathListAppliedTo | Returns true if the current list is the last one from the original. |
| IsUsingAlternateRep | Returns true if current action is using alternate representations. |
| PostDelayedTraversal | Method called by SoMultiPassManager after delayed pass traversals. |
| PreDelayedTraversal | Method called by SoMultiPassManager before delayed pass traversals. |
| ResetContinueActionInBranchFlag | This function resets the continue action flag. |
| SetIntersectEpsilon | Sets epsilon (small value) to be used in the collision computation. |
| SetPipeId | Sets pipe identifier in the range [1..N] associated to this render action while running a ScaleViz Multipipe configuration. |
| SetSceneManager | Set the scene manager associated with this action (if any ). |
| SetUpState | Creates state if it is NULL or it is no longer valid because new elements have been enabled since it was created. |
| StopActionInBranch | This function stops the action in the current Scene Graph branch. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Traverse | Does traversal of a graph rooted by a node. |
| UseAlternateRep | Tell the action to use alternate representations during traversal when available. |
Properties| Name | Description | |
|---|---|---|
 | FilterCallback | Sets a filter which allow the user to continue or not the intersection finding for a pair of shapes. |
Events| Name | Description | |
|---|---|---|
 | Intersection |
RemarksThis 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.
