You are using package pst-vue3d which is obsolete since years. You 
should switch to package pst-solides3d. However, if you want to see
a circle then you have to use the correct viewpoint of the 3d
coordinate system:

\documentclass{article}
\usepackage{pst-vue3d}
\begin{document}

\begin{pspicture}(-5,-4)(5,4)
\psset{THETA=45,PHI=45}
\CircleThreeD(0,0,0){30}
\end{pspicture}%

\end{document}
