Tekton
ekton is an evidence-driven 3D digital reconstruction platform for ancient architecture, specializing in the preservation and visualization of Tang Dynasty timber-frame buildings.
Core trick
Every parametric 3D element carries a source citation and confidence tier, and a verifier rejects any geometry lacking one.
Description
ekton is an evidence-driven 3D digital reconstruction platform for ancient architecture, specializing in the preservation and visualization of Tang Dynasty timber-frame buildings.
Problems We Solve:
Digital Heritage Loss: Ancient architecture lacks systematic digitization, making it difficult for academic research, restoration consulting, and cultural preservation
Traceability Challenges: Traditional 3D models cannot trace the historical evidence of individual components, making accuracy verification difficult
Limited Interactivity: Existing visualization tools lack intuitive playback and control interfaces
What Tekton Offers:
✓ Real-time 3D building visualization with 339 incremental construction states
✓ Evidence Chain Traceability: Every component can prove its historical source
✓ Interactive Playback System (play, pause, speed control)
✓ Precise annotation and documentation of key artifacts like Buddha statues
✓ Integration with actual conservation work and restoration consulting
Tekton bridges digital 3D technology with heritage preservation, providing a comprehensive solution for academic validation, restoration guidance, and cultural asset licensing.
