A Contrastive Analysis on Effect Evaluation of 3D-to-2D Rendering Technologies for Animated Characters

With the rapid development of computer technologies and arts, the 3D-to-2D rendering technologies have been extensively applied to the animation industry. This thesis makes a contrastive analysis on the applications and their effects of two 3D-to-2D rendering technologies in the performance of animated characters. The eye movement data of the subjects were recorded by Tobii Pro XL eye tracker, and the subjective evaluation scores of the two kinds of 3D-to-2D rendering images of animated characters, the characteristics of eye movement data and the relationship between the two were analyzed. The results showed that: there were significant differences in subjective evaluation scores between the two technical schemes; subjective evaluation scores were closely related to the concentration trend of fixation points; the scores of each factor were significantly different; eye movement data such as fixation time and fixation points in the region of interest were significantly correlated with subjective scoring behavior of subjects. These subjective and objective indicators can be integrated to promote effect evaluation more objectively and guide the creation direction of 3D-to-2D rendering technical modeling of animated characters.
