a. Why break down a model?
The most efficient way to create a 3D model is usually to go from general to specific. The simpler the model, the more influence each vertex will have over the final form, and the more likely that once detail is added it will be correct.
This is an ages-old concept taken from traditional art. Whether drawing, painting, sculpting, or 3D modeling, a common starting point is visualizing your desired end result as simplified forms. This ensures that proportion, scale, and shape are correct before adding in smaller details, thus reducing the chance that details which take longer to create are the wrong size or shape.
These drawings clearly show human figures even though they actually consist of cylinders.
