[pstricks] object=plan in pst-solides3d

[Zbigniew Nitecki]

I am trying to draw a triangle in space together with its projections onto the three coordinate planes.  I have no trouble drawing the triangle and the three projected triangles (using \psPolygonIIID), but am totally confused by the behavior of the object plan when I try to draw 
and color the three coordinate planes themselves.  I enclose three minimal codes, and three pictures, one for each attempted plane.  

The xy plane (blue, figure 1.3.1a) comes out as I expect.

The yz plane (red, figure 1.3.1b) comes out in the correct position, but the color is off 
(usually when I invoke red!10 I get a more "pink" color---but here fillcolor=pink gives a similar result to what is there) 
and it is outlined, as the blue one is not (I want it not outlined).

The xz plane (figure 1.3.1c) simply does not show up.

Since my commands for all three are essentially the same (except for the definition), I have no idea what is going on.   Any suggestions/explanations?
