The 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:
- light_source {
<Location>,
COLOR cylinder
[LIGHT_MODIFIERS...] }
- radius
Radius | falloff
Falloff | tightness
Tightness | point_at
<Spot>
The point_at
, radius
, falloff
and tightness
keywords control the same features as with the spotlight. See "Spotlights" for details.
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.
