Antispin simulator

Hi Guys.

I got bored yesterday afternoon, and I was looking at circular motion with ActionScript, so I knocked up a poi simulator that interactively allows you to adjust hand and poi rotation around the hand.

Download poi sim

right click and choose save as - I find the flash player has a much higher frame rate than when the movie is displayed in the window.

I'll probly add another poi and arm, and also strings, and a couple of different trace modes at some stage when I get bored again

patterns you should be familiar with

arm 1 poi 4 - standard flower
arm 1 poi - 3 - antispin flower


if you want to see longer trails just multiply both figures by 2 - eg

arm 2 poi 8 - standard flower double speed double trail length.

nice going joshy

arms and poi on 120 makes some interesting results though

LOL

never tried it that fast!

if you can make your arms go that fast I'm sure they would superposition too!

Josh

wooo Arm:1 Poi:89

next version will have a toggle for persistant trails!

ok loving the high numbers!

single staff antispin = Arm:1 Poi: 179

antispin fire hula hoop Arm 1 Poi: 299

120
118

produces some nice results

I like, has do do something with division of 8 ?

smiling,

:R

Amazing, I know that there use to be an old poi model that you use to be able to play around with, but this is alot better. Thank you for putting this up so we can now all see just how much fun it would be if we could spin like a computer, doing all the moves that we can only dream of.

nice ones guys! beautiful pattern that 120/118

nice going josh.. i look forward to seeing you do that soon.. can you have it down by CG?

just updated the sim.

new features;

- its now got a reset button so you can program it and then have it run the pattern from the bottom (as fire spinners tend to).

-a persist mode, so that you can see the trail stay on the stage - rather than being removed.

-A toggle switch to make the hand visible or not.

next version will have two(!) poi

Josh

With this persist thing you can get some very nice patterns, proper spiragraph stuff!

295 and 300 ^^

according to your persistance setting... the poi will strobe when going extremely fast

well they would if your eye had a frame rate!

Josh

hmmm... thats a very good point

I now see dots

hehehehe... i should point out.. i am also appreciating this as the simulator it was designed to be.. not just crewing around

thanks josh

and... on saying that.. arms 1 poi 61 creates a series of concentric circles

I'm trying to figure out how arm 1, poi 59 will look in real life :P

I just made this: http://www.homeofpoi.com/ubbthreads/showflat.php/Cat/0/Number/833262/Main/833237#Post833262

only to find i'd been outdone. Although I've noticed you can't change the ratio of arm/poi on the animation, and from playing around with my spreadsheet i found that doing this makes some very nice patterns, especially if you have different lengths for each arm and each poi. Is there anyway you could add that to your next version?

oh and is that made in flash? is it easy to? I'd like to know how to make animations so i could make them for other moves. Especially flowers where you're arms change direction, cos they always look really nice

if you put poi on 300, then arms on any multiple of 10 they appear to stop, then going +or- 1 or 2 from there gives nice patterns, especially the ones near some of the multiples of 30

I can pretty easily add a second poi and arm, and I'm thinking of making the shoulder draggable in position so you can place them one on top of the other or side by side, or any other kind of crazy situation!

Also I definitely can add variable poi radius to simulate inside / inverted planes.

It'd be nice to be able to have a programmable sweep function on the poi radius too to make even spirals and smooth transition from long to short...hmmm... possible. but I'm back at Uni now so I'll see how much time I get to do some of the more tricky stuff!

hmmm programmable sweep would be wicked on all of the functions - that would allow simulation of 1.5s and other crazy ass pendula action...

Id also like to add move recognition and naming - ie you put in -1 4 and the name 'anti-spin flower' pops up.

Flash programming is similar to java programming - cept you can shortcut much of the graphics stuff by using Flash's drawing tools and built in objects. However (at least in Mx2004) you sacrifice a lot of the OOP strong structure you get in java. ie flash mx2004 can sometimes just do whacky stuff - that a proper programming language simply shouldn't do.

The whole animation you are seeing is done in code - not tweened or anything like that.

hmm.

Perhaps I could build a file system interface that would load a PoiXML file containing timing, radius, sequence, sweep and speed information that would allow you to run a series of moves in sequence.

I guess then I'd need to write an XSDL...

then I could set up a webservice that you could upload your PoiXML docs to and we could then rate each others routines!

damn geekery.



POIXML.

Wow nice work Josh.

Geeza- 120 118 is trippy!

hmm. I'm currently hypnotising myself at 150 150, and increasing each one by 1 each time. Discovered that that when the numbers are the same, the pattern becomes somewhat 'solid' and if you increase and decrease, for e.g. do 150 150, then 150 151, then 150 150 again, the pattern changes.. yay for little discoveries Bet it was really obvious to everyone else though

ps. Is there a way to manually enter numbers? 229 587 is tripping me out, but it took a lot of clicks to get there! (I'm obviously not using this as a poi tool.. )

229 120 is nice

as is 229 133

229 228 is awesome but upon reaching rys afforementions 229587, they appear similar, but 229228 is slower

There was one which was pretty trippy and started to look very random, but I lost it and couldn't figure out what it was. It looked like a party where people were walking around to strangers, stopping to say hello, then walking off to meet other people..
