Message-ID: Date: 4 Dec 90 06:22:58 GMT Sender: news@murdoch.acc.Virginia.EDU Organization: National Radio Astronomy Observatory Lines: 21 I only really have direct experience with old technology image displays (e.g. IIS) and modern workstations with 8 bit only colour graphics so excuse me if this is a simpleminded question: Are the colour models of modern high end graphics workstations sufficiently able so that, e.g., you can combine two 8 (or more) bit images so that one image controls the intensity and the other controls the hue? (These types of displays under interactive control can be quite useful for displaying related data). Obviously you can compute this in a CPU, the question is are the LUT schemes in modern workstations able to do this. Since the old technology things could do it I'd be amazed if they can't. Still I don't know the answer and I suppose it's possible that a simpler system could have taken over. Thanks.
