[Abstract]:The fast modeling method based on sample has been one of the hot research directions in the field of computer 3D modeling. There is a great deal of demand in the field of animation film and television 3D game to introduce sample modeling into the creation and display of 3D model of animation characters. In this paper, based on the extensive research on the modeling of the sample, according to the characteristics of the animation role model, this paper explores the diversification of the role model from the perspective of model fusion and micro-deformation. Based on the study of the application scope and algorithm characteristics of the two methods, a model diversification random generation system for animation roles is established. Finally, the automatic generation effect of the diverse role scenes is given. The main work of this paper includes the following aspects: (1) aiming at the characteristics of low precision model vertex sparse and widely used map representation, a method based on simplified harmonic mapping is proposed to improve the efficiency of mesh fusion. The content of the source model map is preserved and the transitional map content is generated by using the mapping composition technique, which ensures the completeness of the newly generated model. It has important significance in data reuse and diversification of 3D model. (2) according to the requirements of animation and game field for the diversification of similar characters, it meets the strict limitation of space-time complexity. A method for generating diversified models based on micro deformation is proposed. A new model with the same subject and different details is generated by using the methods of reference deformation and path deformation, which can ensure the efficiency and cost of the algorithm. (3) on the basis of the previous research work, the model diversification random generation system of animation characters is realized. First of all, a parameter schema library is established to store a variety of parameter pattern sets that satisfy the conditions. Secondly, the parameter pattern set is loaded in batches according to the requirements of the scene and in a random manner. Finally, according to the complete parameter information in the parameter mode, the analysis and reproduction of the diversified results are completed, and the multi-character scene of the animation is generated automatically.
