This model was created by Saba Rofchaei and Greg Ward under contract from the U.S. Navy. It is an H-shaped deck space with three lighting configurations (see README file and credits in the repository). Here is a floor plan for the geometry visible in various camera perspectives:
The images above were rendered with the interactive Radiance viewer rvu (see man page) and there is a Makefile with a rule view_all which can be used to render even more camera perspectives of the same scene. This assumes that you have Radiance installed on your computer.
The import into Blender was not fully automated, but I step by step imported geometry into Blender, cleaned up (e.g. by combining several meshes into a single mesh), and slowly assembled the full scene by mirroring geometry from one side of the ship to the other.
