RelaTime3D

Consider the graph

Plot3D[Sin[x] - y^2, {x, -2*Pi, 2*Pi}, {y, -2, 2}]
(*plot to be displayed*)

One way to get a rotatable 3D graph is to execute the following command
which
puts you in the real time mode:

<< "RealTime3D`"

>From now on, any 3D graphics generated will come out in rotatable mode.

Plot3D[Sin[x] - y^2, {x, -2*Pi, 2*Pi}, {y, -2, 2}]
(*plot to be displayed*)

The only relevant information I found was

Information["RealTime*", LongForm -> True]
"RealTimeGraphicsDisplayFunction is display function which allows
Graphics3D and SurfaceGraphics objects to be rotated interactively in
the front end."
(...)

Executing then

<< "Default3D`"

you switch back to PostScript output.

Plot3D[Sin[x] - y^2, {x, -2*Pi, 2*Pi}, {y, -2, 2}]
(*plot to be displayed*)

Can someone explain how exactly happens this changing from PostScript
output
to rotatable object and back?
What is loaded with << "Default3D`"?
