Those are function patterns. ;-)
In POV 3.5, you can make functions directly from patterns. In MegaPOV, 
you have to use a pigment with a Black-White color_map.

Also, check out the additions to the standard includes...

Is this some "insider" joke? Let's take a look at what the "possibly not
useful" features are that didn't make it into the 3.5 self-incrementing
Beta (all of which work just fine thank you):

MegaPOV 0.7
Reflection blur - I've seen enough workarounds in these groups to know this
is needed.
Motion blur - okay, flawed, but certainly useful; I use it often.
Blinn microfacets - superior to specular highlights in every way.
Heightfield_height_at (no way trace works better on hfs, sorry).
Text object enhancements (why use a macro when you can just use this?).
Ini_option (why in the world was this removed?).
Mesh Type 2 (parsed much faster and came out smoother).
Glows (Ahem, Chris, didn't you write this one? ; } ).

POVMan
ClothSim (How is 3.5 better than this?)
Renderman-like Shaders (See falling star animations at p.b.a)

MegaPOV Plus
Particle_system (I know the author is around somewhere).

OK, there are a few things I like about 3.5 Beta+, like the easier
dispersion and improved functions (especially for isos), but, let's face
it, MegaPOV in general is more powerful. The true breakthroughs in 3.5 are
in the superior interface, with enhanced insert menu features, accessible
command line and better error control, but one could easily load MegaPOV
into the bin folder. That is, if you didn't have to keep downloading and
installing the new betas.

and what's the difference (except for a slightly longer syntax)?

hmmm, I've never used standard includes... So I'm not really interested in the
additions
:)

I don't use MegaPOV's reflection blur anymore since I know that the "workarounds"
(using
an average texture_map) gives much better results.  Only problem is when you're using
layered textures...

> Motion blur - okay, flawed, but certainly useful; I use it often.
The only time I really wanted motionblur, the effects were really ugly. :(

> Blinn microfacets - superior to specular highlights in every way.
never used them actually...

> Heightfield_height_at (no way trace works better on hfs, sorry).
trace is a more general approach.  I never used heightfield_height_at
Might be because it's longer than trace :)

> Ini_option (why in the world was this removed?).
ini-options have nothing to do with the scene-file.  They should indeed be separated.

> Mesh Type 2 (parsed much faster and came out smoother).
mesh2 ?  There's no mesh2 in POV3.5 ??
:(

> Glows (Ahem, Chris, didn't you write this one? ; } ).
I don't think glows are really useful.  They would be if you could block them with
other
objects.

> POVMan
yeah, POVMan rules! :)

> ClothSim (How is 3.5 better than this?)
never used it, but you're absolutely right: cloth simulation is a nice thing to have
:)

> Renderman-like Shaders (See falling star animations at p.b.a)
tnx for mentioning my animation :)
And again: POVMan rules!!! :)

> MegaPOV Plus
hmmm, what's new in MegaPOV Plus?

I almost never use the insert menu, and I'm happy with the ini-settings in POV-Ray
3.1...

I really don't understand why POV-Ray 3.5 was made.  IMHO it's a waste of time.  The
POV-Team should have concentrated on starting with POV-Ray 4.0.
I mean: POV 4.0 will be a complete rewrite, so everything they do now will have to be
redone.  What's the point?

Maybe I'm just tired.  I've been awake for 17 hours :)

POV3.5's a big improvement, IMHO.  I no longer even touch MegaPOV or 3.1 :)

MegaPov wouldn't parse a scene in which I used variable reflections...


Does MegaPov have average patterns? I don't remember any, but I've never really
fully gone through the docs either.

To make one thing absolutely clear, and this is not only to you but also some
others in this thread:
You have no, I repeat no, business to tell us how we spend our time!!!  If we
would make a POV-Ray 3.6, 3.7, 3.8 and 3.9, it would be our decision to do so
and you would have no business telling us to not to do it!

The POV-Team is not going to justify any design decisions for POV-Ray 3.5.
There is a reason for everything, and if you are not willing to understand
this, it is your problem alone.  If you don't like POV-Ray 3.5 fine, then
don't use it and quit whining and wasting the time of everybody else!

Thank you for your attention,

    Thorsten Froehlich

Uh oh.. Such comments are not gladly seen by the Pov-team, and I hope you
understand why.. Pov3.5 is their baby.. Well, I think ... surely Pov3.5 is
not a waste of time, you see, it cleans up all the features in Megapov. The
coders do their best to clean Povray - both the source code and SDL - so
that future coders will be able to understand what's going on in Pov and
easily move forwards from that point, to make further improvements.

Pov3.5 takes the best of Megapov, remove the bugs, and makes it the official
version from which all future versions will be build.. I don't see why
Pov4.0 should be a complete rewrite.. Anyway, making Pov3.5 first, is the
logical way to go.. It's like to climp up the stairs, instead of trying to
jump to the top.

Okay, then I would definetely be tired.. Hope you had some rest, when you
read this..  :o)  Peace..
