SAMPLEXYZ(DAT_TO_SAMPLE,XPTS,YPTS,ZPTS) Returns data sampled at a set of (X,Y,Z) points, using linear interpolation.

Arguments: |
DAT_TO_SAMPLE |
Data to sample |
|
XPTS |
X values of sample points |
|
|
YPTS |
Y values of sample points |
|
|
ZPTS |
Z values of sample points |
|
|
Result Axes: |
X |
ABSTRACT; length same as XPTS, YPTS, and ZPTS |
|
Y |
NORMAL (no axis) |
|
|
Z |
NORMAL (no axis) |
|
|
T |
Inherited from DAT_TO_SAMPLE |
Note:
SAMPLEXYZ is a "grid-changing" function; its output grid is different from the input arguments. Therefore it is best to use explicit limits on the first argument rather than a a SET REGION command. See the discussion of grid-changing functions.
The XPTS, YPTS, ZPTS values must be in the same units as the coordinate axes of the variable DAT_TO_SAMPLE.
