Hullo all. I ran a search through the forum in an attempt to find a tutorial on hydraulics. I found a few images posted by someone and while its great at showing me how a real-life piston works, it doesnt really help in the way of Poser. If anyone could toss me a link to a tutorial or point me in the right direction, i would greatly appreciate it.

thanks for posting this again Doc.. questions tho ;) are the shocks modeled as part of the leg or as seperate entities? how does one precisely set the origins? (bascially with number rather than by hand/mouse? well.. how do you work out where to put an origin working from 0/0/0(poser zero point))

Watching thread. :-)

thanks geep, but do you think you could interperate, or if someone else could?

Hi Khai, <------------------------ (does that rhyme?) ;=]

Q. " ... are the shocks modeled as part of the leg or as seperate entities?" A. The "shocks" are modeled as 2 separate objects, i.e., entities. The Upper Piston (UP) is a slightly larger diameter than the Lower Piston (LP). The origin (green cross hairs) may be set using the cursor or with numerical values. The end point (red crosshairs) may be set using the same method as the origin. Access the origin and end points using the Joint Editor (JE) ... Note - (NOT the "Display Origin" in the properties window). JE = [menu] "Window" ---> "Joint Editor" You can usually obtain satifactory results by just using the cursor. After you have set the origin and end points ... Parent the UP to the appropriate body part (or object). Parent the LP to the appropriate body part (or object). Set the UP to "Point At..." the LP. Set the LP to "Point At..." the UP. As long as the parent(s) of the UP (and LP) remain within proper limits, the pistons will appear to slide in/out of each other. - - - - - -

Q. " ... how does one precisely set the origins? (bascially with number rather than by hand/mouse?" A. The origins may be set precisly by clicking on the numerical value with the parameter dial and entering a numerical value. (up to 6 decimal places) Note - P4 only shows 3 places but store 6 places ...P5 shows all 6 places - - - - - -

Q. " ... well.. how do you work out where to put an origin working from 0/0/0(poser zero point)" A. The "origin" is called the "Center Point" when you are using the JE. They are the same location. The absolute position of the object(s) in the Poser studio is determined by the x, y, and zTran values. (an exception to this is when an object is parented to another object) (then, the absolute position is controlled by the parent object)- - - - - -

I hope this answers your questions ... if not, please feel free to ask again. cheers, dr geep ;=]

Hi Furyofaseraph, re: " ... do you think you could interperate" Do you mean "interpret?" ...... If so, interpret what? Sorry, I do not understand what you are asking. cheers, dr geep ;=]

the image you posted...i can tell it supposed to tell one how to make pistons in Poser, but its gibberish to me...i mean i get the basics of poser, its just my mind doesnt work in such a i way where i can extrapolate how to do it from what you posted.

Ah, now I think I understand what you are asking. The picture in NOT intended to show you how to MAKE a piston. It is only intended to show you how to make 2 separate objects OPERATE like a piston. Ok? Would you like to know how to make a piston using only poser? cheers, dr geep ;=]

(Diolma pumps in a bookmark...)

i am aware how to model a set of pistons, thats easy. i know how to make them behave like pistons in 3dMax, but what i dont know is how to you make them behave like pistons in Poser.

Ok ?

LOL smartass. but seriously, thanks, this helps, a lot.

Smartass? ......... for taking an hour to put together a special edition graphic and trying to help explain something?

Sorry, but I guess I am just confused. ;=[

My apologies if I have offended you.

lol, relax...i was kidding... i'm used to forums where people sass me a lot.

Me, too ................. but not usually when I try to help them. ;=[

well, dont get me wrong, i appreciate your help, immensly. and sorry for misunderstanding, but even if you were sassin me, its fine... lol...no worries, mate.

After seeing stills of "Polar Express" all I shall say is "Walschaert". The worrying thing is that I know how to spell "Walschaert". "Poirot", "Simenon", and "Herge" are easy.

No good deed goes unpunished eh? ;) Cliff

I'm so glad this thread re-surfaced. I forgot to save it last time.
Now on HD:-)

Cheers,
Diolma
