Thanks for your prompt reply, Bill. I modified the code to change the
longitude range and disable the texture mapping. The results are still
not what I expect. Can you shed any light on what I'm doing wrong?
latitude = RealType.Latitude;
longitude = RealType.Longitude;
domain_tuple = new RealTupleType(latitude, longitude);
int NCOLS = 5;
int NROWS = 6;
domain_set = new LinearLatLonSet(domain_tuple, -90.0, 90.0, NROWS,
-180, 108.0, NCOLS);
dispGMC.setTextureEnable(false);

Hi John,
The image attached to your email is displayed using texture
mapping, so interpolation is not used. Also, your lower and
upper longitude bounds (-180 and +180) are "equal", so there
would be no meaningful interpolation between them anyway.
LinearLatLonSet is only useful if your application is using
interpolation and you have a truly "circular" longitude
sampling (say every 5 degrees from -177.5 to +177.5). Sorry
to say I don't know of an example using LinearLatLonSet.
Good luck,
Bill

Hello All,
I'm trying to employ the LinearLatLonSet to take advantage of the
longitude "wrapping". Can someone provide me an example of how to
properly use this? Although I can get an image, it's not clear to me
that any interpolation is occurring across the longitude boundary. Test
case is based on example P3_2 in the tutorial and salient parts of the
code are listed below.
int NCOLS = 5;
int NROWS = 6;
latitude = RealType.Latitude;
longitude = RealType.Longitude;
domain_tuple = new RealTupleType(latitude, longitude);
domain_set = new LinearLatLonSet(domain_tuple, -90.0, 90.0, NROWS,
-180, 180.0, NCOLS);
Thanks for your help!
