The documentation for plot3d() <http://doc.sagemath.org/html/en/reference/plot3d/sage/plot/plot3d/plot3d.html>is a little misleading:
----- cut here ----- We draw two parametric surfaces and a transparent plane: sage: L = plot3d(lambda x,y: 0, (-5,5), (-5,5), color="lightblue", opacity=0.8)sage: P = plot3d(lambda x,y: 4 - x^3 - y^2, (-2,2), (-2,2), color='green')sage: Q = plot3d(lambda x,y: x^3 + y^2 - 4, (-2,2), (-2,2), color='orange')sage: L + P + QGraphics3d Object ----- cut here ----- These are not parametric surfaces (i.e., the images of functions R^2 -> R^3), just ordinary graphs of functions R^2 -> R expressed in lambda notation. It would be helpful for the documentation for plot3d() to refer the user who wants to plot an arbitrary parametric surfaces to parametric_plot3d(). -- You received this message because you are subscribed to the Google Groups "sage-support" group.
