HN comment orderThe Nazca lines in Peru seem to align with the shadows of the mountain, I made two videos to demonstrate it: https://x.com/janBuild/status/1796472554905022785 In the second video, you can see that the shadow seems to align with a curved line during summer solstice: https://x.com/janBuild/status/1796473232658518133

Hi HN. I've been learning WebGL and working on this project for about a year. I posted it previously when it worked in 2D and wanted to share it again because the 3D really makes the shade come to life. Most of the credit for the update due to migrating from Leaflet to Mapbox GL JS.
Happy to field any questions about the project.
