         Part 1836:
         Application module: 
         Vertex colours for tessellated geometry
      
      
      
         This part of ISO 10303 specifies the application module
         Vertex colours for tessellated geometry.
         
         The following are within the scope of this part of ISO 10303: 
         
      
      
         - association of colour information with vertices of a Tessellated_face;
 
         - association of colour information with vertices of a Tessellated_surface_set;
 
         - association of colour information with vertices of a Tessellated_shell;
 
         - association of colour information with vertices of a Tessellated_solid;
 
         - specification of colours using integer triples to represent RGB colours or integer quadruples to represent RGBT colour values
            with transparency.
         
 
      
      
         The following are outside the scope of this part of ISO 10303: 
         
      
      
               
         - association of colour information with any geometry elements which are not tessellated;
 
               
         - association of colour information with a Tessellated_edge or a Tessellated_vertex except when included as elements in a Tessellated_shell
            or Tessellated_solid;
         
 
               
         - the specification of semantics associated with the use of colours.
