Study on development tendency of product design rendering

The goal of the product design rendering is to express design concepts and creative ideas through the reasonable recurrence of product shape, color and material quality as well as the description of product function, usability and etc. The designs are often represented by the real or hand-pained object, or being aided by computer or the above all. However, with the development of information technology and changing of people¿s social cognition, traditional design rendering is inevitably undergoing a profound transformation. Although the general tendency is the vision extension in multi-dimensional space, the design rendering has practically evolved into two completely different methods: (1) an independent and complex communication employed by a designer during conceptual development; (2) a mutual communication with multiple perspectives employed during discussion on proposed project. In this article the authors tried to systematically discuss these two methods from both conceptual and technical perspectives, and summarized some experiences obtained during the design practice.
