NAME
|
lampcolor - compute spectral radiance for diffuse emitter |
SYNOPSIS
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. |
