My little attempt at modeling human male anatomy, using just simple objects and
unions (if a superellipsoid can be considered a 'simple object'!) No meshes or
CGS difference/merge, so the model is very quick to render. This started out as
basically a challenge to myself, to see if I could create a reasonable human
facsimile 'from memory' so to speak, without resorting to art or anatomy books
(which I have loads of--but that would have muddied the experient!) It's meant
only as a 'stand-in' model for testing out scenes.

I'm planning on adding this to the POV-Ray objects collection, but wanted to
post some images first, just to give folks a chance to make some suggestions.
But only a *few* please--it's just meant AS a quickly-rendering place-holder,
nothing more. Not something I want to spend *too* much more time at. (Every
time I use this model, I see small ways to tweak and add to it--but lately that
process has been getting a bit ridiculous. so it's time to post the thing.)
Nevertheless, suggestions *are* welcome. :-) And if it doesn't look too useful,
I guess I need to know that as well. :-[

I also posted an animation over at p.b.a, so you can get a better look at it 'in
the round' as it rotates.

It's basically just a static model, as you see it: no I-K or other special
facility for rotating the joints--although that's something I might add later,
in a 'new and improved' version...at least making basic rotation of the parts
easier. And I might even work on that egg-like head!

I want to make him as easy to 'substitute' for a real figure as possible, so a
few questions: Should I scale the model to be 1-unit high? Or some other scale
based on, say, typical imported POSER figures (whatever that scale is)? How
about the y-positioning? (Presently he stands with his feet touching y=0;
should he be centered on the origin instead?)

Since the model started out far simpler, as just a personal project, the various
parts were not made (or placed or scaled) in a truly logical fashion. Kind of a
mish-mash. But as a temporary place-holder model, it serves its purpose.

Hi Kenneth!

The whole idea is excellent I think, and you did a good job overall. The 
only thing that I am really unconfortable with is the head. Imo, it should 
be much more rounded (seen from the side) with an approximately vertical 
*face*.

This would be an attractive alien, though :-)

Great, really!

This is approximately what I would have liked to do to my simple pig figures if
RalLife(TM) and other excuses wouldn't get in the way all the time :-)

I would very much like to have a look into your code, please do post that soon!

Admittedly the head is somwhat strange now, but I'm quite used to exchanging
heads on my figures ;-)

Thank you for sharing your work.

Happy Easter to all
Karl

An ALIEN, eh?  ;-) I guess I do need to re-work that 'egg' a bit! Thanks
for the input.

I'm still curious about my scaling and positioning questions. Since you're quite
familiar with using POSER and/or other 'real' figures, can you give me any
advice?

Coming very soon--after a bit of head modification.

Yes, that shouldn't be at all difficult with my code--everything is in simple
unions. (I hadn't actually thought of that idea--replacing body parts to suit
the user's needs.  Good one! I'll add that suggestion when I post the code.)

The feet at y=0 is a good positioning for any standing figure.
As for the scalling, scaling it in "actual" units, ether imperial or metric, 
seems maybe more usefull than 1 POV unit tall. Usualy, scenes where you use a 
human figure are scaled to real world units.

It it posable?

That makes sense to me, too.  But I've seen other 'human figure' programs that
seem to center the figure on the origin (I think that's how MakeHuman does it.)
But to me, having the feet at y=0 makes more sense.

I didn't know that; interesting. The trouble is, should it be in meters or feet?
Most of the world uses metric units; but here in the 'States, we still use feet
and inches (mostly.)

Well, kind of.  The trouble with my present code is that I never made the
individual parts with that idea in mind. So instead of the upper arm (for
example) rotating AT the shoulder, it may rotate from *somewhere else.*  That
needs fixing in the future. (It's not a quick fix--I would need to reposition
MANY of the parts, while trying to reproduce the same look of the figure.)

As you Americans probably can't even decide whether to use feet or inches,
obviously it should be metric :P

But no kidding actually: what kind of size system would *you* prefer to code
your scenes in - one in which you can easily compute the next bigger or smaller
scales by just moving around the decimal point, or one where you have to
multiply/divide by 12, 3, and 1760, respectively?

.... I mean, if it wasn't for the sake of local tradition of the country you
happen to have grown up in.

FWIW, I think this has been discussed extensively three or four times in 
off-topic. :-)  It seems fixing the scale of a POV-ray model is one of the 
easier fixes, especially if it doesn't make the object move (as in, the feet 
are centered at 0,0,0)
