188.8.131.52 Cylindrical Lights
cylinder keyword specifies a cylindrical light source that is great for simulating laser beams.
Cylindrical light sources work pretty much like spotlights except that the light rays are constrained by a cylinder
and not a cone. The syntax is:
<Location>, COLOR cylinder
SPOTLIGHT_ITEM | AREA_LIGHT_ITEMS | GENERAL_LIGHT_MODIFIERS
radius Radius | falloff Falloff | tightness Tightness |
radius: 0.75 degrees
falloff: 1 degrees
tightness keywords control
the same features as with the spotlight. See "Spotlights" for
You should keep in mind that the cylindrical light source is still a point light source. The rays are emitted from
one point and are only constraint by a cylinder. The light rays are not parallel.
