As a method of dissemination of environmental symbiosis design towards environmental problem solutions, 3DCG pre-rendering animation (3DCGPRA) which has a high quality of representation and has a powerful appeal, is expected to be particularly effective. After arranging components required in an environmental symbiosis design, the representation targets which needed to be developed were clarified. In addition, representation methods of shade and shadow, grass, human activity, and symbiosis methods etc. were developed. In a real project, a 7i 3DCGPRA was created applying these new methods, and its validity was evaluated.
