Show HN: I 3D scanned the tunnels inside the Maya Pyramid Temples at Copan

The linked article is about the archaeological excavation of Temple 26 and its associated tunnels in the ancient Maya city of Copán, Honduras. It discusses the discoveries made by archaeologists, including intricate architectural details, burials, and the complex tunnel system that interconnects various structures within the site. The article highlights the significance of these findings in understanding the history, religious practices, and urban planning of the Copán civilization.

With these 3d captures, you can explore the 4km tunnel system that archaeologists created inside the temples at Copan that are closed to the public. The tunnels are often flooded by hurricanes and damaged by other natural forces--and collapsed on me and my Matterport scanner more than once--so this is a permanent record of how they appeared in 2022-23.

Unlike Egyptian pyramids, the Maya built their temples layer by layer outward, so to understand them, researchers tunneled into the structures to understand the earlier phases of construction. I arranged the guided versions of the virtual tours in a rough chronology, moving from the highest to the lowest and oldest areas: the hieroglyphic stairway composing the largest Maya inscription anywhere, the Rosalila temple that was buried fully intact, and finally the tomb of the Founder of the city, Yax Kʼukʼ Moʼ.

I've been working to build on top of the Matterport SDK with Three.js--and then reusing the data in Unreal for a desktop experience or rendering for film (coming soon to PBS).

Major thanks to the Matterport team for providing support with data alignment and merging tunnels while I was living in the village near site.
