I am trying to use ParametricPlot3D in the form ParametricPlot3D[{fx, fy, fz, s}, ...] where s is a colour specification. I expected that the following two commands would give roughly the same output: In[3]:= ParametricPlot3D[{x, y, 1, Hue[x]}, {x, 0, 1}, {y, 0, 1}] Out[3]= -Graphics3D- In[4]:= Plot3D[{1, Hue[x]}, {x, 0, 1}, {y, 0, 1}] Out[4]= -SurfaceGraphics- But while the second gives a nicely coloured surface, the first does not. I am using In[5]:= $Version Out[5]= SPARC 2.2 (February 5, 1994) What am I doing wrong? Or is there a bug? James Lawry. ==== [MESSAGE SEPARATOR] ====
