It is a process of creating a wireframe model that represents a three dimensional object. That object can be alive or inanimate. A three dimensional model is created using a set of points in 3D space, which are connected by various geometric data such as lines, and curved surfaces.
Modeling Process
1.Polygonal modeling: use basic block to make a basic shape.
2.Nonuniform rational B-spline: trying make the curves smooth.
3.Splines & Patches modeling:visible surface.
4.Primitives modeling: use balls, cylinders, cones or cubes as building blocks for more complex models.
5.Digital sculpting: use digital method to make the modeling.
