The artist studies his materials and methods in order to gain the greatest possible control over his manipulations, so that he may bring out the best characteristics of his chosen technique, and express or convey his intentions.
Every manufactured object represents the culmination of a design/build process. Individuals or teams create design prototypes, but the final product—the real thing—is fabricated by others. The creative phase of product development ends at the moment when goods go into production.
A rendering is a drawing or painting that translates a real-world object, actual or imagined and often three-dimensional, into a two-dimensional image. Renderings are a way in which proposed new products can be visualized. Ideas for new forms and colors are sketched, modified, revised, and ultimately tweaked into a final form ready for production. These illustrations have another, equally important, use. Renderings are a means of selling design and color ideas. They are the principal way in which new product and color ideas are communicated to potential purchasers.
