Abstract

In the process of functionally gradient material entity modeling, in order to meet the design requirements, one needs to constantly change coefficient of material composition equation. In order to facilitate visual design of functionally graded material entities within the distribution, the method based on gradient material source be adopted to directly change the coefficient of material composition functions, and according to the coefficient of material composition equation function image to choose material composition functions. Homogenous approaching gradient is used, the feasibility of change of gradient direction transformatio is proved.
