Anyone have suggestions for the easiest software to build a 3d environment (like in their demo) and drop in scanned models?
Or at least a path to accomplishing this with the lowest barriers to entry?

Back to your comment I'd love to hear what you're looking to do and what you'd need, sounds like I may have explored the same problem space.
There is Regard3D, if by barriers to entry you mean sensor hardware: http://www.regard3d.org/index.php/documentation/introduction
If by barriers to entry you mean technical skills, there are SaaS solutions like Beholder: https://beholder.vision/
About embedding the demo in a web page, I have no idea.
