Ken,

You have hit a problem that I have seen in everything from flight
simulators to animation systems, ie. lights/color values are clamped to 1.0.

So here is my open wish list:
1) Allow values greater than 1.0 to be input and used in the
computation. After all, even a dark grey surface will look white if you
pump enough light into it.

2) Give me 10/12 bit DACs on the IR. Then I can render a moon lit night
scene with values below 128 (or 0.5) but still "spike" the display with
values over 3000 for light sources.

Is anyone from ASD out there listening?

Gerry
