Re: how to fill in pixels


Thanks for your reply. I was not too clear on the
manifold dimension vs. domain dimension,
but I went back and read the Developer's guide
and now it all makes sense.  Using manifold dimension
of 2 in the Gridded3D constructor fixes the problem.

Also, I am not clear on how this solution works:

Is there something that you can point me to
that explains this? Specifically, I don't understand why
gate is radius and elevation is latitude other than
that the units and ranges match ... 
Ideally, I would like to use this solution, because then
I don't really have to compute x,y and z ...

Also, since these are not really longitude and latitude,
will I be able to overlay another cone (at
a different location on the earth) and still have things
work correctly?  The x,y,z solution works, because
my x,y,z is in a co-ordinate system with the center
of the earth as origin (not the apex of the cone).

this works, and I even understand why :)
However, I still don't know how to turn off interpolation

thanks again.
