I think much of the use of dithered colors in LDRAW really paid
off when the dithering was used to imply a different texture,
such as shiny gold, diffuse rubber, or flourescent colors.
I'm currently concerned about what happens to the dithered colors
when LDLite is used to generate 4096x4096 pixel high res images
for printing -- I think the "implied texture" will be lost,
and I'm wondering if I need to expand the dither pattern to make
it stand out better.

| Wow, Lars, that was a lot of code to support r = (r1+r2)/2. The obvious hypothesis would say that the eye performs spatial integration on the pixels, so therefore values are averaged. I guess I can try it on my eyes with L3Lab then. I looked in (...) (23 years ago, 2-Jul-01, to lugnet.cad.dev)
