| lampcolor - compute spectral radiance for diffuse emitter |
| lampcolor [ lamptable ] |
| 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. |
