###### Abstract  
The rising popularity of ecotourism on the Tibetan Plateau has intensified the tension between wildlife conservation and economic development. Conventional wildlife displays often fail to achieve high-fidelity, non-invasive representations of animal morphology and typically lack immersive, interactive features, limiting public engagement in ecological protection. To address these limitations, this study presents a fur simulation algorithm based on the Texture Procedural Overlay Technique (TPOT), integrated with Augmented Reality (AR) technology, focusing on the endangered white-lipped deer in the Sanjiangyuan region. The proposed TPOT-based algorithm enhances the visual realism of fur through multi-layered procedural texturing and physical property fusion. Combined with an AR-driven interactive framework, it seamlessly integrates high-resolution 3D models into real-world environments, significantly improving user immersion and engagement. Comparative experiments demonstrate that the approach surpasses traditional static display fidelity and animation rendering efficiency methods. User feedback further validates its effectiveness for scientific research and environmental education. This work introduces an innovative technological solution for wildlife conservation on the Tibetan Plateau and provides a practical reference for applying digital technologies in ecotourism. animal digitization; animal fur; simulation algorithm; augmented reality; Texture Procedural Overlay Technique 2020 IEEE/RSJ Web Conference  
of wildlife in the Sanjiangyuan region of the Tibetan Plateau, an ecologically vital area often referred to as the \"Third Pole of the Earth\" due to its unique geography and global environmental significance. This high-altitude ecosystem is home to a rich diversity of flora and fauna, including endangered species such as the white-lipped deer, [PERSON]'s gazelle, and snow leopard, along with distinctive endemic vegetation. The Sanjiangyuan region is not only a sensitive indicator of climate change but also a critical area for nature conservation. However, tensions between the demands of cultural tourism and the imperative of ecological preservation persist [5]. Traditional methods of wildlife display, such as field observations and static imagery, often fail to meet the increasing public demand for immersive, informative experiences while preserving fragile ecosystems. In this context, our research aims to explore innovative digital strategies that reconcile the dual goals of ecological protection and cultural communication. In recent years, the rapid evolution of augmented reality (AR) and virtual reality (VR) technologies has presented new possibilities for digital wildlife representation. Nevertheless, existing approaches still face significant limitations [6; 7; 8]. For instance, a VR-based virtual simulation of the Chinese white dolphin combines morphological data and field survey results with conventional texture mapping [9]. Similarly, AR and traditional textures simulate six rare wildlife species but lack fine rendering of skin and fur details [10]. A hybrid hair rendering method with realistic lighting effects has been developed, though it required high-performance hardware, limiting its applicability on mobile platforms [11]. In contrast, virtual animal companions are present in mixed-reality contexts but without an emphasis on conservation [12]. The role of extended reality (XR) in sustainable tourism with a focus on education has been explored, but used overly simplistic animal models [13]. The influence of AR/VR technologies on perceptions of nature have been analyzed; however, that study did not engage with the critical tension between ecotourism development and wildlife conservation [14]. Common limitations across these studies include insufficient realism in fur rendering, limited mobile performance, and a lack of rich user interaction, constraints that significantly hinder their effectiveness in supporting ecological conservation efforts.
