Detailed Description

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

+6.60 Shape

Shape {

The Shape node has two fields, appearance and geometry, which are used to create rendered objects in the world. The appearance field contains an Appearance node that specifies the visual attributes (e.g., material and texture) to be applied to the geometry. The geometry field contains a geometry node. The specified geometry node is rendered with the specified appearance nodes applied. See 4.6.3, Shapes and geometry, and 6.3, Appearance, for more information.

4.14, Lighting model, contains details of the VRML lighting model and the interaction between Appearance nodes and geometry nodes.

If the geometry field is NULL, the object is not drawn.

Constructor & Destructor Documentation

Shape (  const char *  name = ""  ) 
 

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

    		
  







  

    
      

        

          ~Shape           
          ( 
                    
           )

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.

Return a handle on the i th event out of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:
    

  • 0 : appearance_changed
  • 1 : geometry_changed This function is useful, with nbEventsOut() if you want to traverse all events in of a Node.
