Gaussian Splatting in Heritage Conservation: High-Fidelity Reconstruction of Shisi Temple with Aholo 3D

From Ancient Woodwork to Real-Time 3D Immersion

2026.6.3

Introduction: The Challenge of Heritage

Time is the ultimate architect, but it is also the most relentless destroyer. Across the mountains of Zhejiang, China, the Shisi Temple stands as a rare "living fossil" of Song and Ming Dynasty architecture. However, like many wooden treasures globally, it faces the quiet erosion of humidity, structural shifts, and the simple passage of centuries.

Traditional conservation has long relied on photogrammetry, but for complex timber structures, pixels often fail to capture the "soul" of the space. While recent cultural phenomenons like Black Myth: Wukong have brought worldwide attention to the breathtaking beauty of temples like Shisi, the real challenge lies in creating a digital record that is as technically precise as it is visually immersive.

At Aholo 3D, we believe that preservation shouldn't just be a static photo—it should be a dynamic, future-proof digital twin. By utilizing Gaussian Splatting (3DGS), we have moved beyond the limitations of traditional 3D modeling to document Shisi Temple with unprecedented fidelity.

Why Gaussian Splatting for Ancient Architecture?

For years, the industry standard has been "The Mesh." We take thousands of photos, calculate points, and stretch a texture over a polygonal skeleton. The result? Often "plastic-looking" models that struggle with the intricate, porous textures of 800-year-old wood or the way light scatters through a temple courtyard.

Gaussian Splatting (3DGS) changes the game by treating 3D space not as a collection of hard edges, but as millions of learned "splats" or 3D Gaussians.

Atmospheric Depth: Unlike meshes that feel "heavy" and flat, 3DGS captures the volumetric lighting and environmental atmosphere of Shisi Temple. You don't just see the building; you feel the depth of the shadows under the eaves.
Specular Highlights: Ancient Chinese architecture is famous for its intricate woodwork and weathered finishes. 3DGS excels at rendering the way light reflects off these surfaces—something traditional photogrammetry often "muddies" into a flat texture.
The Aholo Edge: Our optimized pipeline is specifically designed to handle large-scale heritage datasets. While raw 3DGS can sometimes produce "floaters" or artifacts in open spaces, Aholo’s proprietary processing ensures a clean, sharp, and enterprise-ready reconstruction.

The Workflow: Bridging the Physical and Digital

Digitalizing a site as complex as Shisi Temple requires more than just a camera; it requires a strategic, multi-layered approach to data acquisition. Our workflow at Aholo 3D is split into three distinct phases to ensure every bracket and beam is accounted for.

Aerial Phase (The Macro View): We deployed high-resolution drones to perform a systematic mapping of the temple’s exterior. This phase is critical for capturing the sweeping geometry of the rooflines, the placement of tiles, and the overall spatial context of the temple within its mountain environment.
Close-up Phase (The Micro Detail): Drones are excellent for scale, but they often miss the intricate "Dougong" (wooden bracket sets) and hidden carvings beneath the eaves. Our team used handheld scanners and professional-grade cameras to capture these micro-details at eye level, ensuring the 3DGS model has the fidelity required for architectural study.
The 3DGS Process (The Volumetric Shift): Once the data is captured, Aholo 3D’s proprietary algorithms take over. Instead of forcing these millions of pixels into a rigid geometric mesh, our system "learns" the scene as a cloud of 3D Gaussians. This volumetric representation is fundamentally more efficient, allowing us to represent complex, non-manifold surfaces—like the weathered edges of ancient wood—with far greater accuracy than traditional polygons.

Results & Visual Showcase

The true power of Gaussian Splatting is best understood when seen in motion. Traditional mesh models often require minutes of "buffering" or massive hardware resources to display high-resolution textures. In contrast, the Aholo 3DGS solution offers instant loading and cinematic fluidity.

Performance vs. Fidelity

While exploring the Shisi Temple reconstruction, notice the lack of "texture popping" or mesh tearing. Our 3DGS implementation allows users to navigate the temple in real-time on standard consumer hardware—including tablets and laptops—without losing the intricate visual fidelity of the original site. This "lightweight yet high-fidelity" characteristic is what makes 3DGS a breakthrough for accessible heritage conservation.

Future Applications

The digital reconstruction of Shisi Temple is not just a visual achievement; it is a foundational tool for the future of heritage management. By capturing the site with such unprecedented precision, Aholo 3D unlocks a range of practical applications that transform raw data into actionable insights and immersive experiences:

Digital Twins for Structural Health: By creating a millimeter-precise record, conservationists can monitor structural shifts or decay over time. Comparing a 2024 scan to a 2026 scan allows for the early detection of issues that are invisible to the naked eye.
Virtual Tourism & Global Education: Shisi Temple is physically remote. Through Aholo 3D's high-fidelity models, this masterpiece of Song Dynasty architecture can be brought to classrooms and living rooms worldwide, fostering global appreciation for Chinese heritage.
Digital Archives: Natural disasters and environmental wear are unpredictable. A permanent, unchangeable digital archive ensures that even if the physical structure is damaged, the architectural wisdom and artistic legacy of the temple survive for future generations.

Summary

Aholo 3D is redefining the boundaries of cultural preservation by bridging the gap between cutting-edge AI and ancient history. Our work at Shisi Temple proves that Gaussian Splatting is no longer just a laboratory experiment—it is a professional, enterprise-ready tool for documenting the world's most precious landmarks.
