Analysis of Three-Dimensional Reality Modeling Algorithm in Animation Design

During animation design process, when the overlap of animation graphics is overtopping, inaccurate three-dimensional feature points appear in the established model, which resulting in low fidelity of model. For this drawbacks, a three-dimensional reality animation design modeling based on an optimization algorithm of animation modeling fidelity is proposed. Triangle refinement method is utilized to refine feature points distributed disorderly in the three-dimensional animation model, so as to obtain a three-dimensional animation composed of triangles, according to the method of calculating the intersection of intersecting triangles, optimal triangles can be achieved, i.e. the new three-dimensional coordinate points are acquired. Afterwards, two-dimensional coordinate calculation is processed for the new added points to get the exact coordinates of the point in the three-dimensional animation model, eventually obtain a three-dimensional animation model with high degree of fidelity.
