new_traversal_scale = old_traversal_scale*lod_state_node_scale new_traversal_offset= old_traversal_offset*lod_state_node_scale + lod_state_node_offset
Note: the affect of nested sglLODStateNodes is cummulative.
After computation of the new scale and offset, traversal then proceeds as if this were an sglGroup node.
Example:
sglLODStateNode *lod_state_node = new sglLODStateNode; sglLOD *lod_node = new sglLOD; lod_state_node>addChild(lod_node); // scales and offsets the range calculations for all sglLOD nodes that // appear below (as descendants of) it in the scene graph lod_state_node>setRangeScale(2.0f); lod_state_node>setRangeOffset(20.0f);

The single precision intersection traversal function which returns the closest object (bounding volume and/or triangle) that intersects with the given intersect segment.
Reimplemented from sglGroup. 

The double precision intersection traversal function which returns the closest object (bounding volume and/or triangle) that intersects with the given intersect segment.
Reimplemented from sglGroup. 

The single precision pick traversal function which returns all objects that fall within the pick frustum.

Make a copy of the scenegraph rooted at this node.
Reimplemented from sglGroup. 

Output the state of this node to the specified ostream.
Reimplemented from sglGroup. 

The single precision cull traversal function that culls out subgraphs that do not lie in the view frustum (stored in the sglCull parameter). Subclasses must implement this function. The entry point for userfriendly culling is in the sglScene class.
