1. We propose a Shape language

• Based on our understanding of "what" shape is.
   
• Driven by the needs of the "markets".
   

2. Its elements are :

• A model for significant vertices and curves:
  • Curvature extrema and ridges and valleys
     
• A model for curve and surface fits :
  • Implicit polynomials
     
• A model for symmetries, scaling, topology and unifying graph:
  • Shock scaffold (related to skeletal models, Voronoi Diagrams and Delaunay tesselations)
