Full radiosity of diffuse surface.

Post by raider » Mon Nov 05, 2012 9:03 pm

Guys, please help me to understand.

If we have diffuse surface, irradiance L, then full radiosity is pi*L.

Irradiance is watt/m^2, radiosity is watt/m^2 as well...
So the question is: why I think total energy is not conserved?
(arriving = L*dA*dt, leaving = pi*L*dA*dt, that's pi times more leaving).

Sorry for such a stupid question, I know I miss something trivial, so please forgive me ))

We do not forgive. We do not forget.

Are you sure that the L is irradiance and not radiance?

Ingenious )) you are absolutely right ) I mixed them up as radiance for diffuse surface is constant over direction, just mixed them up.
