Here is the first version of Viewport boundaries:

This program allows us to see an approximation of the wall surface seen by the user.

In this program i am using an update of my libraries.

Here I use:

• utils.js
• wall.js
• slider.js

I only had to add functions in wall.js to display the area visible by the user.

Now:

• I manage to work directly on the R2D3 section.
• We can create a border around the wall with D3.js.
