Member Function Documentation

leaf()

ErrorCode moab::RayIntersector::leaf ( EntityHandle  node )

virtual

Process a leaf node during tree traversal.

Implements moab::OrientedBoxTreeTool::Op.

Definition at line 837 of file OrientedBoxTreeTool.cpp.

{
    boxes.insert( node );
    return MB_SUCCESS;
}

References MB_SUCCESS.

visit()

ErrorCode moab::RayIntersector::visit ( EntityHandle  node, int  depth, bool &  descend  )

virtual

Visit a node in the tree during a traversal.

This method is called for each node in the tree visited during a pre-order traversal.

Parameters

node	The EntityHandle for the entity set for the tree node.
depth	The current depth in the tree.
descend	Output: if false, traversal will skip children of the current node, or if the current node is a leaf, the 'leaf' method will not be called.

Implements moab::OrientedBoxTreeTool::Op.

Definition at line 827 of file OrientedBoxTreeTool.cpp.

{
    OrientedBox box;
    ErrorCode rval = tool->box( node, box );
    if( MB_SUCCESS != rval ) return rval;
 
    descend = box.intersect_ray( b, m, tol, len );
    return MB_SUCCESS;
}
