Re: Viewing 3D slices of data



Hello Jethro,
to your first question: Add in ParametricPlot3D the option
Lighting->False. (I found it by comparing the options of
Plot3D[{f,s}...] and ParametricPlot3D[{fx,fy,fz,s}...], no idea why you
have to use the option, I think they just forgot to tell, in the Help
for ContourPlot3D it is mentioned.)
As to your second question, check ContourPlot3D.
