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)

(...) Couldn't you just specify "rotate X axis" "rotate Y axis" rotate Z axis"? Something a'la most 3D apps, with an XYZ key visible in the model window would help with this (could be toggled on/off). Matt (23 years ago, 2-Jul-01, to lugnet.cad.dev)

What verbs are better for describing rotation about the standard axes? Rotate is usually understood as spinning about the vertical axis. There are aeronautical terms for the other two, pitch and yaw, and I can't remember which is which, so I'm using (...) (23 years ago, 2-Jul-01, to lugnet.cad.dev)

Hi, I'm wondering how to treat dithered colors (LDRAW 0x0100 to 0x01ff, see FAQ).
