I have a similar issue with Epilog working in ParametricPlot, but not
ParametricPlot3D.
For instance, this works:
Manipulate[
ParametricPlot[{Cos[t], Sin[t]}, {t, 0, a}, PlotRange -> 1.2,
Epilog -> {Red, PointSize[Large], Point[{Cos[a], Sin[a]}]},
PlotLabel -> N[{Cos[a], Sin[a]}, 4]], {a, \[Pi]/48,
2 \[Pi], \[Pi]/48}]
Yet this does not.
Manipulate[
ParametricPlot3D[{Cos[t], Sin[t], t/2}, {t, 0, a},
PlotRange -> {{-1.2, 1.2}, {-1.2, 1.2}, {0, 4 \[Pi]}},
Epilog -> {Red, PointSize[Large], Point[{Cos[a], Sin[a], a/2}]},
PlotLabel -> N[{Cos[a], Sin[a], a/2}, 4]], {a, \[Pi]/48,
8 \[Pi], \[Pi]/48}]
