[comp.graphics.visualization] Hue-Intensity and modern workstations?

bglenden@mandrill.cv.nrao.edu (Brian Glendenning) (12/04/90)

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.
