XYZ plot + Normal to surface output [message #57929] Mon, 07 January 2008 06:41

Dear all,

I am a beginner in IDL programing and I am looking for a few
things :

1/ I have some xyz ASCII files and I want to plot them in a 3D view.
But my X and Y are not regular. Is there any way to plot them firstly
without any interpolation and secondly using kriging interpolation so
as to get regular plot.

2/ I have two files (also in XYZ ASCI format), corresponding to Vx
and Vy of a velocity field. How can I plot the complet velocity field
with vectors in 2D and draped on a 3D surface ?

3/ Using two XYZ files (ASCII format), If I plot them in the same
frame I thus get two surfaces S1 and S2. I want to output the
difference between S1 and S2 but in the normal frame of S1 (in this
case S1 is below S2). Imagine 2 topographies where S1 is below S2.


Thank you for any help !
