The existing methods of mesh fusion for 3D models are based on geometric mesh

which needs sufficient number of vertices to enhance the purpose

to connect components. However

the 3D characters in current games and animations generally use low poly model

which mainly uses a variety of maps to show details. To befit the situation of the low-model characters sparse vertices and extensive use of maps

we propose a simple method of harmonic mapping and averaged-plane to simplify mesh connection process and improve the efficiency. Thereafter

map synthesis based on affine transformation is applied to solve the problem of generation of the new map. Therefore

the new seamless fused model is acquired. Based on methods used in this paper and operational processes of model design and production

a Human-Computer interactive fusion application is developed to implement the efficient 3D model fusion and map synthesis operations. Many experimental results have shown that this approach is fast and effective enough to accomplish the fusion for 3D-character models in games and animations

forms a new character model that is more vivid

and thereby makes more interesting applications.
