a discrete position and affect the entire scene. You can turn the display of
light glyphs on or off while you work. By default, light glyphs are not plotted.
Photometric Lighting Workflow
For more precise control over lighting, you can use photometric lights to
illuminate your model. Photometric lights use photometric (light energy)
values that enable you to define lights more accurately as they would be in
the real world. You can create lights with various distribution and color
characteristics, or import specific photometric files available from lighting
manufacturers.
Photometric lights can use manufacturers' IES standard file format. By using
manufacturers lighting data, you can visualize commercially available lighting
in your model. Then you can experiment with different fixtures, and by varying
the light intensity and color temperature, you can design a lighting system
that produces the results you want.
Luminaire Objects
Light fixtures can be represented by embedding photometric lights in blocks
that also contain geometry. A luminary assembles a set of light objects into a
light fixture.
