Subject: Poser5's "Real World Units" vs the "Real World" ...............

I think I know what has caused the problem. In Poser 4 and previous versions, there were no "RWU" (real world units) defined. The absolute "scale" just kind of "floated" and everyone did their best to scale figures and props to the size they thought look correct with no way to accurately measure anything. I don't remember how I originally came up with the conversion factor of 0.126* = 1 foot but that's what it was. Something I worked out using RayDream Studio (which uses feet and inches) and Poser. *Pnu (Poser native units - from Poser5) If you use 0.126 Pnu = 1 foot, the whole world is happy, ................ at least, I am. And, everything created (with any kind of scale in mind) prior to P5 appeared to work fine using this scale. In Poser5, 1 foot appears to equal 0.116 Pnu. Oops! I thought it was 0.126! Do we have a typo there? This is what creates the discrepancy between my scales and P5. 0.116 0.126 Hmm? Typo? I don't know. I believe what I am going to do is continue to use my original "scale" and ignore P5's "real world" numbers. I have already re-worked all my scale props to "fit" Poser5 but I'm not going to use them and I will not distribute them. Looks like we're going to have a schism here. Pre5 vs Post5 as far as scale is concerned. What do you think? cheers, dr geep ;=]

I always used 1 unit = 100 inches, which comes to 1 foot = 0.120 poser units Some people used 1 poser unit = 8 feet, which comes to 1 foot = 0.125 poser units

What method do you use to determine the scale (size) of your model (figure or prop) for Poser (pre P5)?

Where are you saying the typo exists, in the P5 programming?


geep ( ) posted Mon, 16 September 2002 at 11:02 AM

Jeff,

I am not saying that a typo exists.
I am simply raising the question about the possibility of a typo creating this situation.

It does seem strange though, that if that one digit were changed then we would have essentially the same scale factor that the majority of Poser users appeared to be utilizing before P5.

If the conversion factor were changed now, before items are generated using P5's "real world units," it would eliminate a double standard for scaling within Poser.

But, that's just my opinion.

I could be wrong. ;=]

Just say Don is 6 ft. 0 in. and take it from there. No need to be precise or beat the issue to death. It's about posing and animating figures, not about doing a certifiable surgical planning guide. You can import 1-ft. scales from 3D Studio, Maya or Carrara (or some extinct software like Ray Dream) and they still may disagree with each other.

Most modeling programs allow the user to use a real world scale (feet and inches or metric).

When an object is exported, there is a "multiplier" (or divider) that can be used to control the size.

This is done (I hope I'm not being too pedantic here) so that parts of any given model will have the correct proportions to each other. Picture a car that has wheels that are not correctly proportioned. It will look like a cartoon vehicle. Unless that's what you are trying to render, correct proportioning is very important when modeling.

For example: I use (the "extinct") RDS for modeling and if I change the model's size to 4.2% before I export, it will import into Poser exactly the right size. I don't have to "diddle" with the imported prop's "Scale" until I think it looks right.

Re: using Don=6'0" for a reference, how do I make a doorway exactly 7' tall, or a wall 8' tall?

If you only have one prop in the Poser studio, that may work ok but when you have dozens of props, you could spend many hours adjusting the scale on each different prop trying to get your render to look good.

When objects are not to "scale" and properly proportioned, you may get ONE good render and then change the camera angle and everything will probably not look so good anymore. Hmmm? Back to adjusting scales on different props, I guess.

BTW - Did you want fries with that?

P4 has a scale, it's 1/8"=1'0". That would be .125 = 1'-0". There are 96 1/8 inches in 12 thus 1 = 96 not 100 as some believe. The dials in P4 use real world numbers, in other words, if you move a trans dial .125 you move that object 1/8. What it looks like they did in P5 is take these real world numbers and multiplied them by 100 instead of 96, which is what they should have done. Take number you get from measuring Donk, divide it by 100, and then multiply it by 96 and see what you get.

*"P4 has a scale, it's 1/8"=1'0". "* Scale is actually 1/10" = 1'0" *"That would be .125 = 1'-0"."* Actually that would be 0.125 = 1' 1/2" or (12 1/2") (suggested pronounciation from geep's dictionary) pnu = Poser Native Unit (pronounced "pee-en-yu" or "new") 10.000pnu = 1,000" = (83 1/3') = (83' 4") 1.000pnu = 100.000" = (8 1/3') = (8' 4") 0.100pnu = 10.000" = (0.83') 0.010pnu = 1.000" = (0.083') 0.001pnu = 0.100" = (1/10 inch) = (0.0083') Thus, "Dork" is 6' 3" and "Posette" is 5' 10 1/2". *"There are 96 1/8 inches in 12" thus 1 = 96 not 100 as some believe."* There are 120 1/10 inches in 12" thus 1 = 120 not 100 as some believe. *"The dials in P4 use "real world numbers", in other words, if you move a trans dial .125 you move that object 1/8"."* if you move a trans dial .125 you move that object 12 1/2". (in Poser4) *"What it looks like they did in P5 is take these "real world numbers " and multiplied them by 100 instead of 96, which is what they should have done. Take number you get from measuring Donk, divide it by 100, ..."* The number is 0.752pnu divided by 100 = 0.00752 (case 2) - If you use 752pnu divided by 100 = 7.52 *"and then multiply it by 96 and see what you get."* 0.00752 x 96 = 0.72192" [not correct] (case 2) - 7.52 x 96 = 721.92" [not correct] Take number you get from measuring Donk, multiply it by 100, The number is 0.752pnu multiplied by 100 = 75.2" (6' 2.2") Thus, "Dork is 6' 3" (actually measured on the screen in Poser4) 6' 2.2" is close enough to 6' 3" for me. I'm done. ('cept for P5) ;=] NOW ..... I can go back to designing a new "Scale" that WILL be correct. cheers, dr geep ;=]

In Poser 4, 0.120 pnu = 1 foot.
It is based on 0.001 pnu equal to 1/10 inch.

In Poser 5, 0.116 pnu = 1 foot.

That's 0.009666... pnu = 1 inch
This creates an awkward (strange) conversion factor.
(P5 actually shows 0.009688 on the screen)
(stranger still ...)

I wonder why this has changed ...

Oh well, back to my new Scale prop.

Do you mean Vickey (Vicky, Vicki, Viki)? In P4 or P5?
