IDL and 24 Bits
type: item
description: Hello. I've just got a 24 bit display, and am trying to use IDL more productively than I used it on my old 8=bit display I've read the users guide chapter 16, but still have some questions.. My display (attached to a personal Iris), will only come up in TrueColor mode, which doesn't seem to have writable color tables. xdpyinfo tells me I can't get direct color. How do other people in my situation get color tables and the like working. It seems I could write quite a bit of code to do this, but I'd bet other people have done many things with 24 bits without having DirectColor. Things I am interested in (but my interest is not limited just to this ...) are * Replicating the old Pseudo-Color behaviour (eg, shade_surf,dist(20) loadct,4 does something) without having to go to Psuedo-Color mode * Do shaded surfaces with colors. * Transparent Isosurfaces, ala explorer or some such. (Bet this one is hard ...) * Anything else exciting and new! Thanks for your help.
