It has been quite a while since I've posted any animations here, but I was 
recently inspired by Tim Nikias' website about his particle system to try a 
Matrix style effect with an I/O based particle system. The anim is quite crude, 
but was only intended to determine whether it could be done. It can :-)

Ooh, neat! You should have let it go longer, though, so we could see them
settle down a bit.

Very nice! Is this your own particle system or did you expand Tim's?

When you say "matrix" what does it mean - that it's calculated with static
functions rather than evaluating the enviroment, what ever it may be?  If
so, the only reason I can imagine for using a static approch would be higher
speed of parsing.. At the expense of flexibility. But it could be useful in
some situations, for example water fountains.

Your animation doesn't look crude.. I like it.

Matrix was used to refer to the bullet-time effects
of the movie "The Matrix", not the matrix of
POV...

And he couldn't have used mine, cause he used an I/O
system (its in the headline) and mine is non-I/O. People
always forget that (or never know)... :-)

I knew that it can be done. After all, I/O may be
modelled in such a way that particle may move
slower and slower until they stop, its just the
velocity and gravity have to be influenced appropriately
as not to negate the realistic effect.

But, is it possible for your system to run backwards?

But never mind. I guess everything can be implemented
in a non-I/O as well as an I/O system, its just patience and
knowledge that divides the possibilities. Look at Rune's
system, it supports looping. So, in a sense, it could
support moving backwards through time, as it would
just have to calculate the path of a particle a little less
further...
But sometimes you want nice, easy and intuitive
algorithms and setups, and then its sometimes the
best idea to model programs to fit a certain task.

And I do like the animation, though it should go a
little longer to see the balls drop, and they should
be stretched a little from speed, like you can see
in some of Rune's animations (IIRC) and Chris'
System, and last of all, mine. :-)

I know, but it was just a test.

Thanks! This is my own system.

Matrix, the movie.

I remember this only because the non-I/O approach is so different to my own.

It should be able to run backward. I'll have to try.

Yes, I can't agree more here. This was the first time in about 6 months that I 
touched my particle system. It was a little more difficult to get back into it 
than I had hoped.

Thanks. I think stretching is quite redundant on what is essentially a simple 
test, though.

Nice.  Would be interesting to see how they bounce on out.  Can they remain
stationary on the floor?
