Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

I spoke too soon ... there is still a problem. I do get filled pixels in the xy plane, but things are not filled along the surface of the cone ... instead I get rings. There is a snapshot and source code at: http://www.nssl.noaa.gov/~lakshman/ElevationScan.html a) I am using x,y,z as the domain, so why is the x-y direction working, but not the z-component? b) Is there a conical geometry in visad that I am overlooking here? c) How do I tell the display not to interpolate but use the nearest neighbor? thanks Lak
