I remember there's a way to insert a function instead of a bitmap into
heightfields.
My thorough study of the heightfield and function sections of the inbuilt
docs wouldn't allow me to find this.
Perhaps we could drop hints of whatever this is called into at least the hf
docs....

(Ken, are you getting senile? ;-))
I think a note in both the heightfield and the image_map section would be
appropriate.

I want to put all image input-formats into one section, that would include
df3 and function image.

I'm not sure if that's a good idea, df3 is only used in a pattern
(density_file), but image types are used in heightfields, image_map,
bump_map, material_map, image_pattern and heightfield.

I have suggested this as well. A note and a link to 6.7.11.16 in both
of those sections would help a lot finding that feature.
I don't understand how they succeeded in hiding that feature so well... :)

It isn't really a "function thingy", it just uses them, and it doesn't
have anything to do with height fields, it is just an image type. Look
for a list of the image types...

Christoph,
do you mean, don't put the df3 in such a section, or do you mean don't do
it all?

I meant to leave out df3. Otherwise it seems a pretty good idea
(especially if it includes a few hints for the newbies about which image
formats should be preferred for which purpose).

- Input formats:
description of all types of input that POV-Ray can deal with,
except *.pov, *.inc and *.ini files.
- Image formats:
- TGA
- SYS
- PNG
- ...
- Notes on use
- Internal formats:
- function
- Density formats:
- DF3
(- DF/DFD if it will make it into an official)
(- Font formats ?)
( ... )
This kind of like the setup I was thinking of, but I havn't finished
these thoughts. "Internal formats" could be indented one more level and
be part of Image formats. Font files could be part of it, or not. Where
in the whole structure of the SDL section does it fit best? etc.

It will.
