I'm trying to get a mesh to appear on a surface in Sage 4.8 using parametric_plot3d. Here is the code:
var('u,v')
f=[u-u^3/3+u*v^2,-v+v^3/3-v*u^2,u^2-v^2]
parametric_plot3d(f,(u,-7,7),(v,-7,7),opacity=0.7,mesh=True)
What am I doing wrong? I also can't get any of the examples from the tutorial page to show a mesh.
This is a known bug; see Trac ticket 9708. As mentioned there, the problem is that the keyword "mesh" isn't getting passed on to show. Until it gets fixed, you can use the show method explicitly:
var('u,v')
f=[u-u^3/3+u*v^2,-v+v^3/3-v*u^2,u^2-v^2]
parametric_plot3d(f,(u,-7,7),(v,-7,7),opacity=0.7).show(mesh=True)
