103: 3d Gaussian Splat of Jack Lenor Larsen's Study

This research explores the application of 3D Gaussian Splatting (3DGS) as an alternative computational photogrammetry method for documenting complex interior spaces containing cultural artifacts. The study focuses on Jack Lenor Larsen's personal study at LongHouse Reserve, where diverse textiles, furniture, and Indigenous crafts create a challenging environment for traditional 3D capture due to mixed lighting conditions and material complexity. The methodology employed COLMAP for initial sparse reconstruction through structure-from-motion (SfM), followed by conversion to dense 3DGS modeling using PostShot software. The resulting point cloud was refined using CloudCompare and visualized through Supersplat for real-time web-based exploration. The final model achieved a Structural Similarity Index of 0.811, demonstrating adequate capture of intricate spatial relationships and material details. This approach successfully preserves the contextual significance of artifacts within their original environment, enabling virtual visitors to examine objects in situ while maintaining the immersive quality.
