And yes, Matt those were the points I modelled
and it works

"and the beat counter reads 6
perfect "

yep

It's not quite right if you do in time because the the beats still count

1,2,3,4,5,6

instead of

_,2,_,4,_,6

The In time split time button works fine in 1 plane but when you switch to anothr plane it is reversed. I think this is because the cos and sin for the rotation are contolling the wrong axes, i'll check it out.

I'll code the poi body to be 5 conected points.

oooOOOO, i'm getting excited about the possibilities.

oh, I made it hit itself in the nads

Posted: 6th Jan 2005
haha, thats impossible ~ poibot's way too much fun to watch spin, she must be female...

well done lads.

Getting to the other side

Posted: 6th Jan 2005
Holy crap this has come along...i really need to check poi every second instead of every week

ok ok...dude that wanted the source code...err...you dont want the source code . I promise you....its a terrible uncommented crime against humanity ....but i'll make it available if you're interested

poibot....is...amazing ....so close to exactly what i wanted to be done at the beggining of this thread ...

The freestyle mode is amazing.

The only glitch seems to be at the end of every 'bar' of maxbeats... when he returns to the beginning, he does a little spaz glitch.

I'm finding new transitions just watching him. He did a nice transition from an offset hug to an isolated buzzsaw that I'm totally stealing.

Well, shall we go?
Yes, let's go.

Yeah that glitch is a bitch. It never used to be there, then it appeared, then i thought i got rid of it and now it's back.

I think i know how to get rid of it. It happens because for a split second the beat value is 1 more than maxBeat.

Been watching some awsome isolated butterfly patterns.

When she spins a random pattern over and over it makes the way we define 'moves' seem so arbitery.

Whatcha gonna call her? I'm sure you can come up with something other than Poibot

Posted: 6th Jan 2005
it's always been poibot i'm afraid, been well over a year in the making,

but i'm up for suggestions.

Lol, ok then. Tis not very feminine though

Split time butterflies in the wheel plane appear to be "In time"... though I'd happily admit I was wrong.

If I was doing butterfly buzzsaw and they both hit the bottom at the exact same time, I'd call that 'in time'. If my buzzsaw butterflies hit the front and back at the same time, I'd call that 'split time'.

Poibot disagrees with me.

Am I wrong? I think I might be wrong.

Well, shall we go?
Yes, let's go.

you have no idea how much reading this has made me smile

thanks beautiful geeky people

Geologists do it in the dirt................

Ok dude this thing is amazing, but you clearly have the X, Y and Z pos of every bit of poi so why not move it into 3D!



I was sure flash had a 3D engine (if not built in then as a library)



Swift 3D seems to be flash's 3D animation suite

https://www.erain.com/products/




But yeh, at least when i was whacking it together in OpenGL the hardest bit was working out the positions on the X,Y and Z and just rendering the correct polygons( or models 3D poi model ). Seeing as you have the X,Y and Z it seems the hard bit is over and all you need to do is render a nice 3D poi in the appropriate positions!



It must be done ....especially with your current isometric 3D studio max style display which is BEGGING for that 4th window to be the 3D view

hello just read this and i would like to say i am realy realy confused cos i hate maths lmao
thanks

i am hard but i'm soft, i am fruity but i'm sweet, i am jelly,what am i?

The in time split time thing seems to vary according to the plane, i think i have sin and cos round the wrong way for the localX and localY values in the wall plane. And you're right, if you're doing butterfly In time, then they cross top and bottom, if you do split time they cross left right.


The 3 views are indeed begging for a 4th in perspective. Glass sent me the equations i need to do it in flash. However as musashii pointed out on sph'ism, shockwave has uilt in 3d engine which is far better to use. I downloaded a trial copy of director today and it seems as easy to use as flash, gonna do a 3d tutorial and see how possible it is to rewrite the whole thing in shockwave. Cos at the moment the localZ value (going in and out of your monitor) is a bit of a bodge because in flash ou cannot have 2 movieClips on the same _level, that's why if both poi are at the same depth the green one disappears (beause it draws the green one at a certain level and then draws the red one on the same level, which deletes the first.

If i do it in shockwave i can reder a fully boned model spinning in 3d with a moving camera and particle effect, like ribbons or fire.

I don't think swift is all that, but i could be wrong.


Thanks for all the feedback guys,

DAMN matt, thats brilliant. Wow!

Hey if you press randomize all, it even looks like matt doing his crazy butterfly/isolation/threading combos

Once again, wow, fair play.

Come forth and thou shalt win enternal happiness. but he came fifth so he won an electric toatser.

welp, good luck with the flash 3D stuff. By the ways, how open source is your stuff? After my exams are over and i have some time to breath id definetly like to have a go at porting it to C++ and openGL from flash?

Cheers MOT, that's just the beggining I wish i could spin poi that well, and I wish my poi would pass straight through my body and I wish I could do perfect head isolations but hey. Very addictive to watch tho.

sinjax, once I've tidied up the code it will be available to anyone who wants it. At the moment it is quite a mess. I need to go through it and turn everything into functions, instead of just copy and pasting it all.

good stuff, thats wicked!

I'm going to leave the army and run away to the circus

if not i will just become a MI5 agent !!!

>>When she spins a random pattern over and over it makes the way we define 'moves' seem so arbitery.

that's prolly because we have something called 'collision detection' in our world. we can't spin arbitrary patterns in space -- our own arms and chains (and often faces and nads and other things) get in the way. the other reason I don't know if that type will ever work is because one of the instruments you have to model perfectly is the human body. generating all the possible combinations of angles we can put our body into is equivalent to listing all possible poi angles about that body. the poi are the easy part, and can obviously be simulated (gets harder with tangles, i guess)-- the bodies, though, are near impossible to code more fully than a flexible person could try in real space easier. if it gives us even a few newideas, it's got to be worth it though, right? and it can easily show newbies certain specifics they'd not gotten in their head. I'd concentrate on getting the wrists and elbows to start looking a little more realistic, next. beautiful job coming up with an interface that works so well, too!

well ive just read the first post, not gonna read through all the pages, i do 3d animation and i think your crazy! if you wanted to animate it surely it would be easyer to just have the poi follow a path, that way its easyer to edit and put it natural imperfections to the animation
