RGB to GDL

[eldhead]

Hi,
I´m trying to understand the RGB to GDL conversion,

From the GDL reference manual:

Example:
DEFINE MATERIAL "water" 0,
0.5284, 0.5989, 0.6167,
!Comment surface RGB [0.0..1.0]
...code...
...more code...

How can I translate RGB to GDL?

The decimal numbers are proportional, so that if RBG is normally done from 0 to 255, the GDL numbers are from 0 to 1, so a value of 127 normally would be about 0.5 in GDL.

Hi

I using:

RGB_R= 200 !----    0 to 255
......
DEFINE MATERIAL "water" 0, 
RGB_R/255, RGB_G/255, RGB_B/255, 
.....
