Hi Greg,
Thanks for your info so much.
But I am still confused about what you mentioned in the previous email 'can
characterize the reflectances of materials in each of these spectra,
probably through measurement".
For instance, the green crops will be the objectives in the greenhouse
environment I plan to simulate, what specifically you mean 'can characterize
the reflectances of materials through measurement"
Regards,
Alex

Hi Alex,
The RGB channels can represent any spectral content, so if you have 3 (or
fewer) illuminant spectra, and can characterize the reflectances of
materials in each of these spectra, probably through measurement, then you
can get accurate results from Radiance. If you have more than 3 spectra you
want to try, you can perform sequential runs accordingly. It's a bit
tedious, but people have done it.
Cheers,
-Greg

Hi All,
Currently I was involved in a research on how different coloured LEDs and
the optimal intensities affect plant growth and qualities.
After reading through some info online, I know that it is okay with
simulating sunlight in Radiance but am not sure if it is possible to
simulate different coloured LEDs (such as red , blue, orange, etc)?

Alex
