For this project for Carlsbad Caverns National Park, we documented a historic winding staircase that was part of the original visitor's trail within the cavern. Deteriorating and slated for removal, the stairway needed to be documented before it was destroyed. 

The stairway was captured from eleven scan positions and HDR panoramic photography was used to color the pointcloud. The flytrough of the pointcloud shown on this page was completed in Bentley Pointools. I also experimented with making a panorama from one of the spots on the stairs that could be explored in-browser using the javascript library three.js  The cube environment of a position on the stairway that can be seen here.
