NAME
lampcolor - compute spectral radiance for diffuse emitter
SYNOPSIS
lampcolor [ lamptable ]
DESCRIPTION
Lampcolor is an interactive program for computing the appropriate color for a diffuse emitter. From the total lumen output and a simple
description of the fixture geometry, the radiance for a diffuse fixture is calculated. Since most light fixtures are not really diffuse,
the preferred method is to use luminaire distribution data (see ies2rad(1)).
A table of lamp colors and depreciation factors is used to get the color for a specific lamp type. If "white" is specified, the lamp will
be uncolored. This is probably preferable for scenes with only a single variety of lamp in order to produce color-balanced images.
