Another way to approach this. First, if you will allow me to remake
your text file into this:
(x,y,z)->p
x,y,z,p
1, 3, 6, 1000
2, 12, 4, 1012
8, 18, 5, 1005
9,4, 7, 990
Then in Jython:
from visad.python.JPythonMethods import *
a = load("test.txt")
dumpTypes(a)
you get:
VisAD MathType analysis
FunctionType:
Domain has 3 components:
0. RealType: x
0. Name = x
1. RealType: y
1. Name = y
2. RealType: z
2. Name = z
Range:
RealTupleType has 1 components:
0. RealType: p
0. Name = p
- - - - - - - - - - - - - - - - - - - - - - -
DataType analysis...
FlatField of length = 4
((x, y, z) -> p)
Domain has 3 components:
Irregular3DSet (x, y, z) Length = 4
Range has 1 components:
0. FloatSet (p) Dimension = 1
0. number missing = 0
Is this what's you're after? (Pardon my use of Jython -- it's just so
much quicker for me.....).
