The Constructing And Application Of Top-Down Color Design Model

The theme of this dissertation originates from the National High-Tech. R&D Program for CIMS - Research on the Computer Aided Conceptual Design for innovation of the product (Grant No. 2002AA411110). The dissertation elaborated the importance of implement for supporting to Top-Down design in computer aided color design. At present, to unite color design relative theory researching Top-Down color design implement means and to construct the supporting system became important research contents of computer aided industrial design.With the research of Top-Down color design process, analyzing color design domain knowledge, combining color harmony theory and the concept color scheme database, through the mapping tree establishing the mapping relationship between concept color scheme and product model part, the paper has constructed a Top-Down color design model TPCDM. Three Top-Down color design mode were proposed. They are each based on freely matching colors, color harmony theory and concept color scheme database. Using TPCDM, a computer aided color design system frame supporting Top-Down was established. The paper has studied the system module realization method and has carried on the development: has researched the freely colors selecting and matching module realization method based on the HSV color space, and realization method for application of Ostwald color harmony theory on the computer; and realization method of mapping tree which is used to establish mapping relations. A concept color scheme database was Designed and constructed, has realized two, three, four colors type concept color scheme for repeatable use. Initially develops the prototype system, has realized the integration with the 3D design platform SolidWorks2006, and has carried on the application in the product color design, effectively enhanced the product color design effect and efficiency.
