Polygon mesh models have been widely used in various areas due to its high degree of verisimilitude and interactivity. Since the mesh models usually undergo various phases of signal processing for the purpose of storage, simplification, transmission, and deformation, the perceptual quality as well as the visual experience of mesh models are often subject to distortions at every stage. Therefore, investigating the perceptual quality and the visual experience of mesh models have become one of the major tasks for both the academia and industry. In this paper, we have designed two subjective experiments to investigate the perceptual quality and the visual experience in both the virtual reality environment and the traditional 2-D environment. Experimental results showed that there is no statistically significant difference in the quality perception between the two viewing conditions, independent of the model content, the distortion type, and the distortion level. On the contrary, there exists significant difference in the visual experience between the two viewing conditions under various factors. This paper helps researchers to better understand the quality perception behavior and the visual experience toward polygon mesh models.
