Hi, Yes of course that's it... 12 or 16 bits color displays had it. A decade ago! In the SGI days, many systems did double-buffer by halving the color space to 2x12 bits, dithered too.
Nevertheless, for 24 bits "true color" it would look nicer too :) -Ton- -------------------------------------------------------- Ton Roosendaal - [email protected] - www.blender.org Chairman Blender Foundation - Producer Blender Institute Entrepotdok 57A - 1018AD Amsterdam - The Netherlands On 6 Jun, 2013, at 14:10, Brecht Van Lommel wrote: > I can't find good info on it either, maybe it was only ever used for > OpenGL color index mode or displays with less than 8 bits per color > channel? > > The dither implementation is not specified by the OpenGL > specification, and it's valid to not do any dithering at all. > > On Thu, Jun 6, 2013 at 12:58 PM, Ton Roosendaal <[email protected]> wrote: >> Hi all, >> >> Someone pointed me at the banding, visible in shaded 3d viewports with >> greyscales. >> None of the systems I tried (mac nvidia, mac ati, linux nvidia) shows any >> dither in the viewport... and there's nothing in the code pointing at being >> disabled. >> >> I checked it with a print in the graded backdrop drawing: >> printf("dither is %d\n", glIsEnabled(GL_DITHER)); >> >> And it says it's on. >> >> Screenie, with expanded color range to see the banding: >> http://www.pasteall.org/pic/52953 >> >> Shouldn't it show a nice stipple pattern?
