Documentation Talk:Reference Section 6.1

Regarding the note at the end of http://wiki.povray.org/content/Documentation:Reference_Section_6#Media

The casting of a shadow depend on the kind of media concerned.

Absorbing media always cast a shadow.

Scattering media also cast a shadow unless it's extinction is set to zero.

Emissive media never cast shadow.

I would suggest reordering the 3 sampling methods descriptions.

Start with method 3.

Then, put the warning followed by methods 1 and 2.

A few minor suggestions:

Section 6

Transformations apply only the density statements -> Transformations apply only to the density statements

There should be a consistent capitalization for the first word in a "Note"

Section 6.1

The emission keyword specifies a color of ... -> The emission keyword specifies the color of ...

Although we say they "emit" light, this only means that they are visible without any illumination shining on them. They do not really emit light that is cast on to nearby objects. -> Particles which emit light are visible without requiring additional illumination. However, they will only illuminate other objects if radiosity is used with media on.

a scattering media -> scattering media

, additionally samples Min=Max so a single samples parameter is acceptable. -> This doesn't really seem to belong in the box. Rather, when describing samples Min, Max below, add "The value for Max may be omitted, in which case the range Min = Max will be used".

a max samples higher than the minimum samples -> a maximum number of samples higher than the minimum number of samples

Generally, commas are set a bit sparsely. Here are some which should probably be there for grammatical correctness:

After "for example" (2x) After "However" (3x at beginning of sentence) Before "i.e." After "For object media" After "In addition" After "Typically"
