Coordinate system with tikz-3dplot

1

I am trying to use tikz-3dplot to draw a cube and I was particularly interested by the possibility to define a point using tdplotsetcoord which allows to get x/y/z/xz... coordinates. But when I try to define a point in (4,4,4) of the main coordinate system of tikz-3dplot (so tdplotsetcoord{P}{sqrt(3)*4}{45}{45} I think), I do not get what I am expecting as you can see below. The blue and black nodes should be the same in my figure. Any ideas ?

documentclass[tikz]{standalone}

usepackage{tikz-3dplot}

begin{document}



tdplotsetmaincoords{70}{110}

begin{tikzpicture}[tdplot_main_coords]



% cube

tdplotsetcoord{P}{sqrt(3)*4}{45}{45}

  (0,0,0) -- (Pz);

draw[->] 

  (Px) -- ++ (1,0,0) node[anchor=north east]{$x$};

draw[->]

   (Py) -- ++(0,1,0) node[anchor=north west]{$y$};

draw[->] 

  (Pz) -- ++(0,0,1) node[anchor=south]{$z$};

filldraw[dashed,blue] (0,0,0)-- (P) circle (2pt);



filldraw[dashed] (0,0,0)-- (4,4,4) circle (2pt);
