Arul V Posted almost 3 years ago How much of structural (shape) changes have taken place to the objects since it was invented? Thanks for your reply. This called as customization of objects. Customization is doing some modification over an existing object or modifies the already existing. The shape of the objects never changes since invention/discovered. For an example: There is an always possibility circular or any other shape can have best behaviours than hull shape. This can be applied to any objects.
