ABSTRACT
This chapter discusses polygonal and spline modeling, introduces different types of modifiers and deformers that can be used to quickly model complex shapes from simpler ones such as primitives. It also introduces efficient and time-saving group of techniques collectively known as constructive solid geometry. The chapter looks at various modeling techniques and categories starting with primitives. It also discusses a modeling technique that is closely related to primitives called polygonal modeling, and also looks at some specific techniques that are applied using polygons. The chapter covers deformations that can be applied to simple primitives to create complex, intricate shapes. In computer graphics, a set of objects known as primitives are used to approximate simple geometric shapes. In polygonal modeling, the 3D scene objects are generated by putting together many flat surfaces, known as polygons or faces. One common method employed to create such realistic 3D models is to use texture and map them onto the 3D-modeled objects.
