You can compare the process to construction with lego and sculpting clay. Just like lego, you can add blocks to your 3D model, and like sculpting clay you can shape these blocks to your liking.
We start with a basic 3D shape, known in the industry as a ‘primitive’: a simple cube, sphere, cylinder, or another basic 3D shape. These 3D shapes are all made up of polygons, and we can manipulate individual polygons, or the whole shape using a range of techniques to stretch, squeeze and sculpt the primitive. In this way, we gradually bring out the 3D vision.
We manipulate the polygons using ‘modifiers’ which are a collection of varied actions that can be applied. A modifier could be a chamfer that is added to the edges of a shape. One of the most used modifiers is the ‘turbosmooth’ that divides all of the polygons in the whole shape into four making the whole shape higher definition. So, if a circle has sixteen sections, we apply turbosmooth, to give it now sixty-four, which makes it look rounder, and also allows us to sculpt in finer detail.
