Well, it is an optional feature of emission media. I added two optional
keywords: emission_method and emission extinction that have meaning only
in the case of emission media. Specifying emission_method 1 is the same
as standard pov. I would have preferred a syntax similar to scattering
(emission { type, color, extinction }) but I haven't taken the time to
find out how to do this while staying compatible with the current
syntax.
To Rune:
Of course there are ways to do something similar in straight pov and
you'll get more flexibility that way. But it is impossible to get
exactly the same effect and you need a lot more code to get results
especially if you've got a complex media (remember TonyB's mediagames
last spring?)
