In my Poser 7 by experimenting I have found that 1 Poser Native Unit of length = 103.20 inches = 2.621 meters. Is this correct? Why choose such a value for the Native Unit instead of a  rational multiple of an inch or of a centimeter?

It's a (very) long story but ...

Dr Geep uses 1.000 Poser native units (Pnus) = to 100.0 inches.

e.g.,
0.100 Pnu = 10 "
0.010 Pnu = 1"
0.001 Pnu = 0.1"

That makes the conversion between the two extremely easy. .

If you want to see the exact number Poser uses, change the
interface to inches, feet, meters, etc, and after each change
look at the Poser.INI file.  The UNIT_SCALE_FACTOR number will show
the value.  For instance, when the interface is set to feet, the line is

UNIT_SCALE_FACTOR 8.600000

which means 8.6 feet per PNU.

... depending on which version of Poser that one is using. :lol:

And it's even more fun because the default figures are not re-scaled
for each version.  Jessi and James were apparently built in 5 for use
in 6, but somebody changed the scale between versions and didn't
bother to recalibrate the figures.  So J and J are freakishly tall when
measured by Poser's own values in 6 and 7.

And ...

That's why I use Dr Geep's Scale (DGS) ... It is valid for ALL versions of Poser and has not changed since the very first version of Poser circa '94.

Use the link (above) and download a FREE 9 foot or 1 meter scale prop for use in Poser - ALL versions.

cheers, ... and happy measuring :

P.S. If you use the link, make sure to scroll down to see a really neat example !!! :biggrin:

I'm an old model builder, built model ships etc. before I got into computing. I approched the scaling issue as follows and works well for me.
The base v4 mesh is .739" tall, assuming the average woman is 5'5" tall then
65/.739=87.9 so the approximate scale is 1/88th.
I don't know if 5'5" is the actual average height for women, it's just the number I picked that seemed reasonable.
This all doesnt help if your just working with Poser but I use it when building objects in my 3d modeling program(Carrera) then import the obj into Poser.
The math tells me this all should be correct, but I do find some objects built to this ratio seem a bit large when imported into Poser for some reason so I just scale them down till they look right. But my starting point and the scale I build to is 1/88th

Poser 7 Reference Manual (page 24):

"ONE POSER NATIVE UNIT IS THE EQUIVALENT OF 8.6 FEET, OR 262.128 CENTIMETERS"

Yup, ..................... and the beat goes on ..... and on ....... and on ..... ;=]

But ............. It must be true ................ if it's in the "Manual," right?  Page 24? .... :huh:

Thanks anyway but I think I'll stick to DGS ......... because ................. it works. ... ;=]

I use the SWBG scale that I found works perfectly for all software programs and all versions thereof.  --been using that scale since well 1995.

SWBG= Scientific Wild Butt Guess scale--Jan

Please don't think I'm arguing because I'm not.
But if I export the base v4 figure obj and scale it times 100 and import into Carrera with auto size unchecked It measures 73.93" tall. Thats Approximatly 6'2" tall
If I bring it into my uv mapper and check properties it's hieght is 73.93"
So what am I missing or where is the descrepancy unless the v4 figure is supposed to be 6'2"

Um, I am not arguing either but ...

Who ever said that Poser peeps are "normal?" ... :b_confused:

cheers,

P.S. The bottom line is  .................. Do what works for you.

I have mine set to "inches", not that I understand "inches" being from a metric country, but bagginsbill uses inches for his settings and I tend to use a number of his shaders and stuff, and well, they just don't look the same when used with a cm setting.

Besides, so far as I'm concerned there is no "measurement" and distance inside Poser. I haven't a clue how tall things are, or the distance things are from each other.  I just turn dials until I get a placement that I'm happy with. So all of this measurement stuff inside Poser seems really weird to me :)

Then, you need one of these. 

@geep: Seems you missed the point. The OP wrote:

"I have found that 1 Poser Native Unit of length = 103.20 inches = 2.621 meters. Is this correct?
"*

I answered with what a PNU means in Poserworld. I think that nobody here knows it better than the people who wrote Poser. So,

"ONE POSER NATIVE UNIT IS THE EQUIVALENT OF 8.6 FEET, OR 262.128 CENTIMETERS"

should be correct and the OP is ok with what he found out.

It's cause V4 (like her older sisters) is not really 'average' Her mesh is close to 8 heads tall, which is firmly in the 'idealized' height range. A more average height for women is somewhere between 7-7 1/2 heads. And note that if the 8 head V4 is 73.93" tall, then a 7.5 one would be 73.93" * (7.5/8) = roughly 5'9" which is much closer to an average.

So geep's 1:100 unit thing is actually pretty close for most work. You would need more precision if you were adding your characters to archi/pre-viz type work but for artistic renders it's an easy to use alternative.

Well, using the handy-dandy 9 foot ruler I got the following:
As a reference, average height of American Female 5'6", Male 5'10"

Poser Figure Heights:

Aiko 3 - 5'9"
Aiko 4 - 6'2.5" - (Her growing 6" is why I don't actually use her.)

dr geep <--------------------------------- loves these heart to hearts re: "scale"
;=]

1 inch = 2.54 centimeters exactly by definition by law, at least here in Britain.
So, 1 foot = 12 inches = 30.48 cm
1 yard = 3 feet = 914.4 cm
1 mile =1609.344 meters.

You guys are very silly, with all this stuff.

The question was very simply asking what is the ratio of a PNU to a Poser Inch. Nobody asked how tall Vicky is.

And it seems none of you actually knows the true answer.

The true 100% correct answer (not an approximation) is 1 PNU = 103.200005 Poser inches.

I know you think I'm silly, but it matters sometimes. I do very precise displacements in Poser shaders. I generate these shaders (MT5 files) so I must use the MT5 format. In MT5 files, displacement is expressed in Poser inches, always, regardless of your display unit. For certain displacements, if you use 103.2 instead of 103.200005, you will get visual artifacts.

For most uses, 103.2 is a decent approximation, but it is not exact.

By the way, the Poser Hi-res sphere has a diameter of .1 PNU, or 10.3200005 inches.

This is also the precise height of the Poser box, and the one-sided square.

Actually 103.200005 also may be an approximation.

I have some evidence that the ratio is actually

103.20000458

However, I've never noticed any visual differences based on that figure versus the other.

By the way, the Poser Hi-res sphere has a diameter of .1 PNU, or 10.3200005 inches.
This is also the precise height of the Poser box, and the one-sided square.

Bagginsbill, love it!!!!   Additionally, the height of a received Poser box must be adjusted by the variable USPSC factor.  Jan

If your building any props, furniture, buildings etc. they need to be proportionate to the characters in the scene. The only way size and scale is not important is if your using the charachter as a stand alone.
So determining the height of a poser figure is not silly at all.

I didn't mean that scaling a chair to fit Vicky is silly.

I mean that it is silly to talk about how tall Vicky is when you're trying to convert Poser inches to Poser Native Units. That was the original question.

The answer is not "Vicky is 6 feet 1 inch." The answer is 103.200005

Quote - The answer is 103.200005

Damn! And there was I thinking it was 42!

Um, ................ maybe ....... 42.200005 ? ...

LOL 42 is the answer to the biggest question of all (well perhaps the Poser height question) and required the most powerful computer in the galaxy to compute--wasn't that computer destroyed for an intergalactic bypass by the Vorgon Construction Fleet?   Jan

yup   ;=]

Quote - 42 is the answer to the biggest question of all

It's The Answer to "The Ultimate Question of Life, the Universe, and Everything"

Quote - ... required the most powerful computer in the galaxy to compute

The Answer was calculated Deep Thought, which was the second most powerful computer.

... wasn't that computer destroyed for an intergalactic bypass by the Vorgon Construction Fleet?No, that was the Earth (it was programmed to find what The Question is).
The computer that calculated The Answer, designed the Earth :tongue2:

I notice that nobody mentioned the fact that the builders of the computer that informed us that the Answer was 42 also spent so long waiting for the computer to tell us that that they forgot the question and had to build another computer to reverse engineer the question itself! :biggrin:

--and then it (the computer designed to reverse engineer the answer to get back to the question) was destroyed in order to make way for the hyper space bypass (love folks who have an advanced degree in HGG).  Jan
