<<Is there any way to dither the 15-bit rendering display to eliminate
the banding often apparent in this mode?>>
If you want dithering in the rendered image itself, it seems you will
need to use an IPAS routine. Yes something could be done in the
driver, but the image would be a lie. When you tried to output the
image to a device other than the screen, you would again see the
banding. You aren't the first to ask the question though. Anyone
want to work with us on an IPAS for this???
Brian:
IPAS? Did you say IPAS? <g> Sure, we'd be interested! But what
happens if you just press the "16 bit" option button in 3DSR3?
I don't understand why dithering the 15-bit image in the driver would
be a 'lie': the banding is a result of displaying a true-color image
on a display that can't handle 24-bit depth. Let's say I am saving
the images to full 24-bit targa files. If they are output to video or
print, they'll show 16.7 million colors. Since the Hicolor display
can only display 32k colors, a dithering option would give a more
accurate approximation of the 24-bit image.
I realize that inexpensive video adapters are available which offer truecolor,
but I don't make the purchasing decisions around here.
What do you think?
