The methods of geometric modelling differ from one to another based on the level of information completeness of the features in objects. Figure 2.22 shows the evolution of modelling methods. Wireframe modelling is historically developed for computer aided drawing but only for the representation of key vertices and boundary edges. Solid modelling is the most advanced modelling technique since it is capable of representing the complete information of solids and beyond. Other methods such as surface modelling, boundary surface modelling (also called B‐Rep or Mantle modelling), and space decomposition are between the extremes of wireframe modelling and solid modelling in terms of the completeness of information about solids.
