[Therion] CaveView a 3D web viewer

[Xavier Robert]

Hi all,

I have work on that a bit more on that. 

1) The developper has updated the code. See https://github.com/aardgoose/CaveView.js/issues/4 and https://github.com/aardgoose/CaveView.js/tree/master/build

2) I downloaded the missing files and the updates. I still have the same problem in my browser (Safari 10.1.2) :  « failed loading cave information »
In the debugger, I have the error : « XMLHttpRequest cannot load file […] Cross origin request are only supported for https »
A quick googling points that this is because I am working with Safari in local… I moved to Firefox, and that’s working. —> For mac Users, do not use Safari to test with local files !

Cheers,

Xavier

CaveView also has some nice features like highlighting a specific height level, by specific survey section, etc.

I went to the fulldemo website (https://aardgoose.github.io/CaveView.js/fulldemo.html <https://aardgoose.github.io/CaveView.js/fulldemo.html>), and I open the development plugin from Safari. I add a snapshot in attachment that show the different scripts used by the website.
