```Hi,

and rewrite it into an implicit function, like
If[2 - y^2 - z^2 < 0 || 2 - y^2 - x^2 < 0, 1, 0]

and use ContourPlot3D[] does not help ??

You man also cut the two parametric surfaces with
the implicit versions by hand.

Regards

Jens

| Hello,
|
| I did not describe my problem accurately in
surface intersection.  I should have said:
|
| I wish to plot the region bounded by the
surfaces x = Sqrt[2 - y^2] and z = Sqrt[2 - y^2]
which lies in the first octant.  I wish for the
plot to be limitd to only the region bounded by
the surfaces.  My best attempt is
|
| ParametricPlot3D[{{Sqrt[2-t^2+0.00001], t, u},
{u, t, Sqrt[2-t^2+0.00001]}},
| {t, 0, Sqrt[2]}, {u, 0, Sqrt[2]}, ViewPoint ->
{2.75, 2.4, 1}];
|
| However, this shows more than the region bounded
by the surfaces.
|
| Any ideas?
