#10215: Sage's plot3d() is very poor compared to Mathematica's Plot3D[]

Following a request to test the following 3 lines of code on #8433
{{{
y=var('y')
B=plot3d(sqrt(sin(x)*sin(y)),(x,-2*pi,2*pi),(y,-2*pi,2*pi),viewer='tachyon')
B.show()
}}}
I did this on Sage 4.5.1 running on Solaris 10 and found no problems of
excessive CPU time as reported at #8433. However, the quality of the
output leaves a lot to be desired, and appears to show discontinuities
which are not in the function.
Attached are two images showing the output from Sage using the above
commands, and Mathematica 7.0 using the following command
{{{
Plot3D[Sqrt[Sin[x] Sin[y]],{x,-2 Pi, 2 Pi},{y, - 2 Pi, 2 Pi}]
}}}
It would be good if we could improve this.
