Blender ought to be able to handle that.
Not obvious from thier web page.  Does any one use it?

I have Blender but I find it rather difficult to get my head around. However, I just had a chat with my Blender expert friend who says that it's perfectly possible to do fly-throughs inside the model, and it doesn't even have to be 'rendered' as an animation, but can just be interacted with in real-time. I'll load up a model now and just see what it looks like inside ;)

Re: DistoX2 an alternative - PCB

re #23  I am interested in a PCB for a Cavetron. 
My only slight hesitation is that the 2D scanner is only rated to 12m with a white target by the manufacturer. However, it may be that the laser is operated at a bit more power by the Teensy compared to the board that the scanner is supplied with.

The RPlidar A1 does have a 12m radius (so it will scan the sides of a 25m diameter passage if your going down the middle!) The 12m limit is a limit of the lidar itself so you wouldnt be able to increase that.  However you can do multiple lidar traverses and overlay them (one down each side of a passage for example), but this wont help you out if you have a passage this is more than 12m high.

There are other lidars that have a wide scanning range (Such as the Rplidar A3), however at around £500 it is considerably more expensive than the £65 A1 version.

Potential other software options:

Meshlab
Paraview

Haven't assessed the suitability, just throwing them in.

re #28 RPLIDAR.

It seems there is also an A2M6 with 18m scan radius, currently just over $300.
I wonder if the 12, 18 or 25m ranges are real in the low reflectivity setting of most caves; particularly since the Slamtec info mentions white walls.

I think both meshlab and paraview were part of my workflow for turning survex data into an STL for 3d printing. There's a thread on here somewhere. I didn't use any of the functionality other than import and export, hammer to crack the nut of file conversion.

Company ive worked at used meshlab for working with lidar point cloud, photo, and radiation scanner data. It's very powerful, and free!
