6.11.11.2.12 Normal and Radiosity
Radiosity estimation can be affected by normals. To enable this feature,
add normal on to the radiosity{} block. The default is off
</manual>
In with way normals do affect radiosity? Where can I find more detailed
explanation of how some options/algorithms work (how they work in phisics
model, and how they are computed by Pov) - apart from source code?

By default the normal modifier is not taken into account when
calculating the illumantion of a surface caused by radiosity samples.
This means that if you have a surface (not illuminated directly by
any light source) with a normal modifier, it won't show any (it will
be flat, as if it didn't have any normal modifier).
By turning this option on, you can make POV-Ray to take the normal
modifier into account. (The reason why it's off by default is because
it slows down the rendering.)
