It just doesn't do what you want it to do because "Epilog is an option
for graphics functions which gives a list of graphics primitives to be
rendered *after* the main part of the graphics is rendered."

In the case of 3d-graphics this means *after* the projection of the
3d-model was projected onto the 2d drawing window:

"In three-dimensional graphics, two-dimensional graphics primitives can
be specified by the Epilog option. The graphics primitives are rendered
in a 0,1 coordinate system. "
