The full 3D-views of the original and re-parameterized curves

Just as before we overlay the two graphs which also include the t-variables.
All the following plots are full 3D-plots -- feel free to rotate them any way
you want. We simply display three special projections:

The top = xy-view

The xt-view alone

The yt-view alone
