I am confused as to the use of the VERT_COLORS keyword
with the IDLgrSurface object. I tried using the BYTSCL
function to get vertices coloured according to data
height but without success. I have fallen back on a
single colour for the surface; while I can see the
overall shape, small-scale features like ripples are
hard to observe.
I would appreciate advice on (i) how to get vertices
coloured according to field height and (ii) general
ideas for colouring surfaces that are either aethetically
appealing or aid in bringing out small-scale features
without losing the overall shape.
Cheers,
Darran.
