Hi Stefan
Regarding point 1, the visad data object corresponding to the function
type that you mentioned
is a FieldImpl. You can extract the flatfield with the FunctionType
((lat,lon)->Temperature)
by using following FieldImpl method:
data.getSample(0);
It will get you the first flatfield (or let say first image) in the
sequence.
Regarding second one, I am not able to understand the query exactly.

Hi,
i have some question about data transformation or resampling.
1) I have some data that are defined like this
(time->(lat,lon)->temperature).
a) Is it possible to transform/resample the data to
(lat,lon)->temperature?
(The result should be a n x m grid with temperature values.
b) I want to get the value information for a specific
coordinate (in this case lat/lon).
field.evaluate(LatLonRealtupleType) is not working, because
of the wrong mathtype.
2) I'am using screenbased axis with TwoDDisplayRendererJ3D . Now i want
to set the clipping area to the bounds of the screen based axis. But i
have no clue how to calculate the clipping area. For testing, i tried
to use the cursor position as a clipping boundary.
double[] cursor = getCursor();
float tmpXMAX=(float)cursor[0];
tmpXMAX=1-(tmpXMAX-1);
setClip(0, true, tmpXMAX, 0.0f, 0.0f, -1.0f);
But it is not working as aspected. The boundary is only correct if the
cursor is exactly over the right side of the box (cursor position = 1).
I think i missed some kind of transformation. Maybe someone can give me
a hint.
Thanks a lot
Stefan Below
