I'm currently researching the lighting system in Omniverse and have some questions about certain light source properties

Omniverse Core Platform
1

1. Are DiskLight, RectLight, etc., Lambert radiators? Do they follow the spatial distribution of luminous intensity conforming to cosine law?

2. Can the Intensity property of a light source be understood as intensity per unit area, equivalent to radiance? Yet, in the description of the light source’s Intensity property, it is labeled as ‘power’

3.I’ve noticed that increasing a light’s area actually boosts its light intensity, even though the Intensity value remains unchanged.

4. The Intensity property of DistantLight differs from other lights. It states: ‘Scales the emission of the light linearly. The DistantLight has a high default intensity to approximate the Sun.’ Other lights describe their Intensity property as ‘Scales the power of the light linearly.’ What’s the difference between these two descriptions?

5. The scale property has no effect on DomeLight. Can we assume DomeLight’s radius r is infinitely large? If so, when I calculate DomeLight’s power using 2*pi^2*r^2*radiance, the result is infinite. Is this correct?

Hi there and welcome.
The lights in Kit are measured in NITS, with the exception of the distant light which is lux*pi at the receiving surface.
1 Nit is equal to 3.426 lumens
