In the field of computer graphics 3D modelling is the process
of developing a mathematical representation of any threedimensional
surface of object using a specialized 3D
modelling software. Using 3D modelling techniques we can
represent a object in digital space. Within the software
package of a 3D modelling software 3D models can be
automatically interpreted and visually represented as
geometric objects made up of edges, vertices, and polygonal
faces.
