Hi all,
I am working on adding a function library to povary.co.uk and not being
familiar with functions, am a little stumped on how I can categorise them.

Well, you can start with the purpose of the function...if they are meant
to be used as patterns, in other functions, as isosurfaces...
Also, if they are meant as isosurfaces, you will need to provide info
about the intended threshold. The max_gradient and contained_by would
also be important.

you have gone to complex! - I was hoping for a simple list :) - I have not
done anything with ISO surfaces and the like - period, if it can be made
understandable to me, then anybody should be able to use the library
the intention is not just to provide a list of formulas, but include a
rendered image, sample source, and any other notes that the functions author
feels the need to share (and anything any others have to say as well), its a
question of how I can break a long list of items down into easily find-able
sections
(or if anybody fancies joining the staff with the post 'master of functions
')

Catagories: Pattern, object & other
Per catagorie by description of the result?
"plane with bubbles"
"maze with rounded corners"
"Isoflower"

I did give a list, categorize them by intended purpose: pattern,
component of other functions, isosurface.

Ok...functions are useful for more than just isosurfaces. You can also
use them as patterns and as pieces of other functions.

Category: Patterns(functions intended to be used as patterns)
The Patterns category requires the function itself, a simple
description, and a preview image.
Sub-categories:
Noise patterns(anything that is similar to granite/bozo/wrinkles)
Wood patterns
Geometric patterns
Other patterns
Category: Building blocks(functions intended to be used as parts of
other functions)
Requires the function itself, and a description. May have a
preview image.
Sub-categories: none
Category: Isosurfaces
Entries in this category require the function, sign, and
threshold value used, a description, and a preview image. Information on
max_gradient and contained_by would also be useful. In fact, everything
other than the texture and interior would be useful.
Category: Parametric surfaces
Objects done with the parametric object. Requires a description
and image, as well as the object minus texture and interior, like the
Isosurfaces category.
You may also want isosurface and parametric categories in an object
library, because you can make many interesting objects by combining
isosurfaces and textures.

My personal nitpick, ignore at will:
Isosurfaces have nothing to do with the International Standards Organization.
The prefix "iso-" means, roughly, "same." An isosurface is the surface you
get when you visualize all points in a field that have a given (the same)
value.
