Abstract: In the 3-D visualized simulation of hydropower project, the CG (Computer Graph) knowledge base is employed in line with the designing characteristics and visual features. With software CATIA and 3DS MAX as the application platform, ideas of the implementation and main technologies of CG knowledge bases inclusive of 3-D parametric model base, 3-D grid model base, and material base of hydropower projects are discussed. The details such as link decomposition, elements classification, model-establishing methods, and key issues are also explored. Through the application of CG knowledge base, the 3-D visualized simulation scene could be built rapidly, the production cycle of similar project can be shortened, and the level of application automation can be improved.
