ARROW in 3d? [message #31681] Sun, 11 August 2002 19:19

Hello,
I need to add some arrows, on the x-y plane of a 3-d SURFACE plot.
Seems that IDL's ARROW routine, and one_arrow.pro from the Astronomy
library only work in 2-d - there's no /t3d option.

I could modify one_arrow.pro as it uses PLOTS, which accepts /t3d (or
write a routine from scratch using PLOTS) - but surely this has been
done before? Is there already a 3-d arrow plotting routine?
Thanks,

RW
