Detailed Description

MFNodeSplitter node is used to split MFNode into certain SFNodes yet.

This is normally used to make the routing from MFNode to SFNode easier.

Indexes is a initialized only filed which takes multiple integers and be used to decide which indexes of the MFNode will be extracted. If the indexes specified value is bigger or equal than the size of MFNode, the no actual content will be extracted and output. If specified indexes is less than the size of MFNode , then the corresponding node will be taken and be set into a SFNode with the name "sfnode_"+index.
Examples:

• MFNodeSplitter.x3d ( Source )

Member Function Documentation

traverseSG()

void MFNodeSplitter::traverseSG ( TraverseInfo &  ti )

virtual

traverseSG is called once per scenegraph loop on the scene in order to traverse the scenegraph.

During this traversal things can be updated in the node and HapticObject instances to be rendered should be added to the TraverseInfo object.

Parameters

ti	The TraverseInfo object containing information about the traversal.

Reimplemented from H3D::Node.

References H3D::Node::traverseSG(), and updateSelection.

Member Data Documentation

updateSelection

H3DUniquePtr<UpdateSelection> H3D::MFNodeSplitter::updateSelection

protected

Specialized field used to update the output sfnode_[index] fields values.

C++ only field.
