This paper presents Negative Shanshui, an AI-powered real-time interactive simulation technique. It reinterprets classical Chinese landscape paintings to convey a message about the ecological crisis of the Anthropocene. The system optimizes the Stable Diffusion model for real-time inference and integrates gaze-based inpainting and frame interpolation to create dynamically changing animations based on the viewer's gaze. Furthermore, it is presented as an interactive virtual reality (VR) experience. The paper describes the entire technical pipeline, including the system framework, optimization strategies, gaze-based interaction, and multimodal deployment in an art festival. Furthermore, analysis of visitor feedback collected at the exhibition reveals a range of responses, including empathy, ambivalence, and critical reflection.
