The average radiance across a particular field of view

Hi Radiance Community,

I have been looking into ways to implement the view angle and direction to irradiance calculation (preferably with the ‘rtrace’ program but I am sure if that’s possible) as an input to calculate the radiant flux for a given field of view, to compute the average radiance across a particular field of view (watts reaching a defined field of view). My priority is to use solid angles as input to the program.

If anyone has experience in this area, I’d appreciate any tips you may have.
Thanks!

Hi Parisa,

I’m not 100% sure what you are asking, but you might want to look at the rsensor tool, which takes an angular sensitivity function and traces importance samples to estimate a specific sensor output.

Cheers,

P.S. I don’t know where to find the man page on the website, so I’m including it below for convenience.
