Using Thomas' patch plot3(x,y,vvv) gives the expected result.

I also have no problem with mesh(x,y,vvv).

Although I'm running the default branch from jwe's mercurial archive,  
I don't see a record in the ChangeLog that indicates anything has  
changed since 3.0.0 was released.

Have you tried Thomas' patch to plot3? ... and what problem do you  
encounter with mesh?
