#16bit display dithering
5 messages in this thread
I have noticed that when I am rendering with the Targa+ set to tmode 17
(640x480x16bit), that 3DS seems to be dithering (not dithering like
Floyd-Steinberg dithering, but something like dithering) the image as it
puts it on the screen. Is there a way to turn this off? I would like it
to look the way it does if I use gettga to display the image in this mode.
I've looked in the manuals, but the only references to dithering I can find
are to DITHER-256, which is another thing entirely.
Thanks.

The ADI driver handles dithering to non 24-bit devices. I'm not sure if
the T+ driver gives you a way to turn that off. If you don't want to
dither to 16-bits, render to the null device with the tga-depth 3ds.set
option set to 16.

Garry,
thanks for the tip but it didn't work. With TGA-depth=16 and Rendering-
device=NULL. The TGA image was stored as a 16bit dithered TGA.

You're right… we always dither our 16-bit output. The only way to get a
non-dithered image would be to convert a 24-bit file to a 16-bit version
with an external utility.

You can't turn off the dithering when rendering in 16bit mode. I had
the same problem. Render in 24bit mode and then convert your 24bit
TGA in a 16bit TGA with an external converter like ImageAlchemy.
