Kevin,

Apparently in 3D graphics, you can only render 2D graphics using Epilog.
>From the 'advanced' help (the 'more information' section) of Epilog:
     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.

Hope this helps,

Maarten

The following gives me an error. I would have thought that Point was a
Graphics primitive, but vers 6 says no. Any help would be appreciated.
BTW a 2D equivalent works fine.
Plot3D[Sin[x y], {x, -2, 2}, {y, -2, 2},
  Epilog -> {Red, AbsolutePointSize[7], Point[{0, 0, 0}]}]
