Under what license is this library?

I am trying to convert the Mindbomb 3D Ball Screen from JS/Codef to C# for conversion to C++/DirectX which I have wanted to do for years but I am having problems with the perspective calculations.

There seems to be no documentation for codef_3d.js

I have tried to separate the shape definition from the transformation but I still don't understand how this works.

Given this setup:
my3d=new codef3D(ballcanvas, 400, 40, 1, 900 );
my3d.vectorball_img(myobjworm, ball );
my3d.group.scale.x=my3d.group.scale.y=my3d.group.scale.z=30;
my3d.group.position.z = mover;
And these rotations:
my3d.group.rotation.x+=0.00;
my3d.group.rotation.y+=0.04;
my3d.group.rotation.z+=0.00;

Is this updating a COPY of the shapes definition:
my3d.group.children[i].position.y = siny-2;

But how is this transformed for display into real x,y coordinates?
Are the bobs transformed and then sorted in Z-order so the furthest away are displayed first?
What are the perspective calculations given the depth of the field and current mover position?
