Rulers in SL are 18cm out!

Am I the only one that enjoys being really small?

Nobody is probably interested in this, but a possible way to measure an avatars height is using the physics engine...

You could build a contraption that people go stand under and then drops a block on top of them. The moment the block hits the avie, you measure it's position, relate it to the 'bottom' of the contraption. This should get you a fairly accurate height of the avie, including it's attachments/hats etc. etc.

Of course, this process is kind of painful for the avie...

(And of course you need to correct again for the bounding-box/0.1m physics issues in SL... so nvm. I guess it could score points on novelty though...)

The bounding box for an avatar is also inaccurate - it's top is above your head, and does not take into account any AO's that change your posture. For example, if I am in a quad dog form, 24" tall at the shoulder, the height of my bounding box is as tall as if I was standing up, with no AO active. Which means I can't run under the table... The bounding box collides with the table edge.

Physical measuring is also iffy, because attachments are phantom, and don't affect your bounding box. So if I am in a furry vixen form, with a prim head and prim hair, the bounding box is the same as if I didn't have the head and hair prims on me.

I have seen several measuring devices that allow you to check height visually. they allow you to move a horizontal bar up or down until it just touches the top of your head, and then tells you the height from floor to bar, accurately.

I would suspect that any HUD or scanner that tells you a close to accurate height for people around you does so by calculating an offset from the height that either llGetAgentSize or llGetBoundingBox return.

Shouldn't the client have the information needed to tell you your height, including your attachments, pretty accurately, since it has to draw you?

Nevar! XD

Heck, even my "tall" shape is really short... 5'10" or something like that. (^_^)

I should dust off my old Scaled Height Bar... That texture was really nice. I used to offer it as a freebie at the hangout, but, I never boxed it and it's bloody huge. Maybe later today or this weekend I want to arrange a quick photoshoot so I can put a box together and leave it up on more freebie racks around. =^-^=

Your height bar is the only thing that can measure tinies properly Immy.
The scripted one never take into account that to be smaller the AV frame is folded with animation tricks.

You can easily see this in a group of different AV types clicking a scripted height marker, any tinies there don't touch it since we know they are always wrong for us.

You just need to linked the measuring part to a platform for precise measurements.
Make the base the root prim leaving it solid and the scaled part a flexi that is as stiff as possible to force that part phantom, this trick works. You get a solid base with a phantom post. Plus it will be a spam free measuring tool that works for just about any AV.

No more arguing with glitchy scripted height markers!!

Sorry if this is off the topic slighty - it was the closest thread I could find to my question.

My partner has an island and its total area is supposed to be 65,000 sq meters (it actually says it on her land settings), and yet to an avatar, it looks about 1/4 of that. If it really were that big, it would take some time to cross it just walking, but it doesnt seem realistic scaling at all. Can anyone tell me if Linden use their own scale for meters (maybe there is a "Linden Meter" or something ) But after reading this thread, I see you guys are measuring your avatars at near real world sizes, so it seems that avatars and terrain do not have the same scale. Any help would be really appreciated.

Your expectations may be off...an island only needs to be 256x256m to reach 65K-ish square meters.

I guess i notice it a lot mainly because i come from an FPS gamer background, thus when i move around i'm most of the time in first person view.

I suggest peoples that know a bit about scripting to try to fiddle with their default 3rd person camera settings. I got pretty nice feedback with some kind of shoulder cam (off centered so you cans ee what you do, flat angle and low/close position)

The default camera gives a "diving" effect that makes things look smaller than they are.

A sim/region in SL is 256 Meters on a side. To put that in perspective, it equals about one city block in most urban areas. By actual measure, about 843 feet, or not quite as much as 17 city lots that are each 50 feet wide on the edges facing the street. There's plenty of department stores in my home town that cover more land area than an entire sim.

A Meter in SL is the same Meter as in the real world. But most of us are not used to thinking of area as square meters, or of distances in Meters. The fact that most avatars end up about 25% oversized, due to the many causes already mentioned in this thread, means that distances in SL seem even smaller than they really are.

I went and rezzed a copy of my scaled height bar in the hangout deck again. It's near the freebie rack, and it's still a no-mod item so that the scale stays consistent from one to the next. (^_^)y

Cool. I'm actually 5' 6" (height detect scripts peg me at 5' 2"

i set my Avi to as close to my real hight as I could get using phantom box method and removing my hair,you do push you hair down when getting measured in RL with either a bar or ruler so this is fairly accurate.

then made a prim floor that was 10 feet by 10 feet 3.048 meters then using a ground sit from my AO moved the floor around until it was lined up like i was sitting leaning against the wall and my toes looked like they should sitting in a 10 foot hallway

then made the floor a cube set to the bottom of my feet the top or the cube looked about where a basketball rim would appear to be from my persecutive.

finally i went to a RL source Auraria Panthera,my truck a 2007 Freightliner Expedite truck,measured one of the tires and made 2 cylinders that matches Roia's tires spaced them apart like the back axle and low and behold the tire hits my chest at just about where it should.

So i don't think there is an 18 inch drift any place it's perspective and builders using over sized avies to scale stuff if you have a 7 foot tall Avi anything basically over 2 meters things should look small if built to RL measurements

Maybe you have a 5 foot 6 or 7 Avi using stuff that is built for a 7 to 7 and a half foot tall Avi that would make it look like things are 18 inches off because in RL things are not built for somebody that tall unless they are custom made.

Final analysis there is no 18 inch disparage it's a combined optical illusion of cam view and the builders scale being off.

I use the one in the forum hangout. I go at odd hours when you are all asleep. I poke around. Sit at the bar (drink a soda). Measure myself.
It's hard to gauge height in sl. I am relatively short in real (5 feet 4) but had to grow 6 inches to fit my partner's animations. If anyone knows where you can get an accurate height detector please let me know.
If we know how tall we are, how much do we weigh? A 7 foot woman must weigh pounds and pounds and pounds.

Silly fool 110-120 just like we weight at 5'2" gods!

Not so sure about that Mjolnor, Oh "Hammer of the Gods" - its not liek a 5 footer is elongated with same body mass. These 7 and 8 footers would be monstrous in real.
'Course its all a bit of yer old metaphyscials innit? Liek how many angels can you fit on teh head of a pin.

*shrugs* It's all a matter of perspective, isn't it?

And honestly, I don't think LL can/will fix the issue until they get a better avatar mesh. Avatar mesh will fix some proportion issues, as well as those ugly shading issues.

I think those height detectors measure to the height of your eyes. So there is the whole top of your head causing you problems.

------------------

Toy excellent point, except of course that 90++% of men on the internet claim to be 8 inches.

The dozens who have volunteered that information to me (with pictures*) over the years are proof. Of course I never did actually ask .. And why they bring it up when you aren't even interested in them, I have no idea.





*Conspicuously no rulers are ever included with said pictures.

If height seems screwy, it's a paragon of precision compared to SL mass. See http://lslwiki.net/lslwiki/wakka.php?wakka=lindogram for speculation on how the unit of mass got so screwed up. And here's a little scriptlet that "weighs" you in the conventional "lindogram" units, and capriciously converted to metric and imperial units:

default
{
    touch_start(integer total_number)
    {
        key toucher = llDetectedKey(0);
        float toucherLindograms = llGetObjectMass(toucher);
        float toucherKg = toucherLindograms * 100;
        integer toucherLb = llFloor(toucherKg * 2.2);
        float toucherOz = (toucherKg * 2.2 - (float)toucherLb ) * 16.0;
        llInstantMessage(toucher, "You weigh "+ (string)toucherLindograms + " 'lindograms'
            which at 100 kg/lindogram, would be " +(string)toucherKg+ " kilograms
            or " + (string)toucherLb + " pounds " 
            + (string)llRound(toucherOz) + " ounces.");
    }
}

You may not want to use this if you have self-image issues. For scrawny Qie, it reports "You weigh 1.699289 'lindograms' which at 100 kg/lindogram, would be 169.928900 kilograms or 373 pounds 13 ounces."

(So it's even more useless than the height detector scripts.)
