Advanced modelling
In the chapter on basic modelling (Chapter 5) we considered the creation of primitives and their modification using standard deformations and transformations. We also considered creating Boolean objects. In this chapter we are going to introduce:
- creating 3D objects from 2D drawings using lathe and extrude commands;
- creating arrays;
- creating NURBS surfaces.
Using lines and shapes
So far we have worked with 3D geometry that is represented as a wire frame and is visible when rendered. The process that we are about to undertake begins with shapes, which are (generally) 2D forms. The term ‘shape’ usually refers both to a closed set of lines (a square, a circle), a line (straight or curved) or an open connected series of line ...
