First, the Autoscale zoom option seems to always give the ! reply.


If you try to plot a half a sphere using:


This should be a sphere of radius 4. You'll notice these extreme jaggies as it gets close to the plane z=0. At first, I thought it might just be rounding errors, but if you use a radius of 10, you can see the blank areas are much taller in the z direction than 1, which means it's not rounding error. It should be flush with the plane z=0.

Try plotting the following:



That'll plot the semi-sphere and the plane, which gives the following (the semi-sphere should be flush with the plane)...

Perhaps that has to do with the TRIANGLE command, but Wofram Alpha doesn't do much better. for that reason I requested a parametric-3d plot some time ago.

Actually, wolfram alpha does do it better. However, you can see the jaggies in wolfram as it looks like it draws it and then fills in the jaggie gaps without shading, so you see them as a lighter shade.
