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.

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? | | Thanks in advance. |
