Detailed Description

Here is the documentation for this node type, from the ISO standard.

+6.42 Normal

This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (e.g., IndexedFaceSet and ElevationGrid). This node contains one multiple-valued field that contains the normal vectors. Normals shall be of unit length.

Constructor & Destructor Documentation

Normal (  const char *  name = ""  ) 
 

Construct a node with all its fields set to default value, which is equivalent to the code below: 

    		
  







  

    
      

        

          ~Normal           
          ( 
                    
           )

Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.

Return a handle on the i th event in of the node or a "unknown" typed handle if there is no such node. emarks This class has no eventIn. This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.
