(...) I'm using a simplified form of bezier curves, like you see in most drawing software like coreldraw etc.. this is also x = f(t), y = g(t) and z = h(t) with f, g and h being a*t^3 + b*t^2 +c*t + d . a, b , c and d can than simply be calculated (...) (24 years ago, 26-Nov-00, to lugnet.cad.dev)

(...) Yes indeed! Would I simply change the reflectivity of the color? That seems pretty easy; I'll try it when I get home. Thanks! Dave! (24 years ago, 24-Nov-00, to lugnet.cad.dev)

(...) If I recall correctly, the FAQ says to use the same color code (#383).

Is there an LDraw color code for silvery metal other than bright chrome? I'm thinking something more along the lines of dull silver-grey, like the wheels on some Technic sets. Any guesses? Dave! (24 years ago, 24-Nov-00, to lugnet.cad.dev)

I feel really silly, but do any of you old-timers remember who wrote LIGHT.DAT? I don't have a clear recollection. I'm pretty sure it was either James, Lutz, or Lars. Anyone? Anyone? Steve (24 years ago, 22-Nov-00, to lugnet.cad.dev)
