Re: Gidded2DSet

Hi Eugen,

The first dimension in your float[2][3*4] array should be the
fastest varying dimension (VisAD convention), so this should
work if you invert the [3*4] arrays.

Hi there,

are only quadratic Gridded2DSets allowed?
Or: Why is a Gridded2DSet with the following coordinates not valid?

new float[]{0,6,9}   // X-Coordinates
new float[]{0,7,8,9} // Y-Coordinates

Which makes up the following float[2][3*4] Array of Coordinates:
[[0.0, 0.0, 0.0, 0.0, 6.0, 6.0, 6.0, 6.0, 9.0, 9.0, 9.0, 9.0],
[0.0, 7.0, 8.0, 9.0, 0.0, 7.0, 8.0, 9.0, 0.0, 7.0, 8.0, 9.0]]


A VisadException Exception is thrown in the Samples consistency test of the Gridded2DSet class, line 171 ("Gridded2DSet: samples do not form a
valid grid (0,0)").

The values of the variables at the point of the thrown expection are:

i= 0
j= 0

xpos= -42.0

w1= -42.0
w2= 12.0
w3= 54.0
w4= 0.0
v00= float[2]  (id=38)
        [0]= 0.0
        [1]= 0.0
v10= float[2]  (id=39)
        [0]= 0.0
        [1]= 7.0
v01= float[2]  (id=40)
        [0]= 0.0
        [1]= 9.0
v11= float[2]  (id=41)
        [0]= 6.0
        [1]= 0.0

So, w2, w3 and w4 would cause the exception to be thrown.
Is this intended?


Thanks for your help!


Best wishes,
Eugen
