The VR-based virtual exhibition system has become a popular solution for the remote exhibition of paintings. The existing virtual exhibition systems have successfully created an immersive experience of being in the exhibition hall. However, as for the presentation of Chinese Hand-Scroll Paintings (CHSP), they still have two insufficiencies. First, CHSPs are fully displayed pure images and can not be manipulated in the original way of scrolling. Second, the essential aesthetic experience of the “recumbent tour” in the painting has not been interpreted intuitively. This thesis proposes an exploration of a virtual exhibition system to complement these deficiencies.

We adopted two methods to achieve this goal. First, we applied the conventional method of “simulation” to recreate a virtual CHSP and simulate the interactive functions of a CHSP. Second, we adopted the method of “generation” to reconstruct the virtual scene of the diegetic world and drive the VR user’s virtual movement in the diegetic world by following the generative logic of the aesthetic experience in classic Chinese aesthetics.

However, the Chinese “perspective” is different from Brunelleschi’s pinhole perspective. This means that conventional 3D reconstruction methods and estimation methods of viewpoint position based on pinhole perspective are not applicable for our research. For this, we established the projection transformation model in the CHSP based on the analysis of its visual structure and inferred the corresponding 3D reconstruction algorithm and estimation algorithm of the viewpoint’s position. We realized these algorithms as script modules and integrated them into the virtual exhibition system. The system is presented as a VR application that features an interactive display and visual interpretation. It has a built-in virtual CHSP that can be manipulated in an original way and will synchronously interpret the CHSP by reproducing the experience of touring in the painting.
