>Does anyone know how to clip the ViewingBox of a ParametricPlot3D. >You can specify the range of the values for the z-coordinate by >using PlotRange -> {val,val}, but I did not find a way to specify a >range for the x an y coordinates. PlotRange is a very versatile command. PlotRange -> {zmin, zmax} PlotRange -> {{ xmin, xmax}, {ymin, ymax}, {zmin, zmax}} PlotRange -> { Automatic, {zmin, zmax}, All} are all possible settings. Thus In[3]:= ParametricPlot3D[ {Sin[z] Sin[t], Sin[z] Cos[t], z}, {z,-Pi, Pi}, {t,0,2Pi}, PlotRange -> {{ 0, 1}, {0,1}, {0,1}}] is what you are asking for. >I would also be interested in viewing cuts of ParametricPlot3D, >where I could specify a plane which intersects the object and all >the points above or below the plane are left out. Perhaps anybody >has written a package to deal with this problem. This is an interesting idea. My initial idea would be to write a package that ended spitting out a ContourPlot command.
