 Particular Bobbylize? by Billyson Apr 6, 2005 at 10:43:47 pm

I'm wondering if this is possible? I'd like to make particles that have liquid like properties like merging but that look solid and are geometric. How is this possible? I'm also wondering how you would morph particles. Like a fellow member asked, example: a circle fills with particles, then the circle morphs into a square or some other geometirc shape and the particles shuffle around to fill the new shape. think of those old rice commercials where the rice builds different objects on the plate, or the bread commercial for bergen where the bread grains form different symbols.

Where do I begin? How would I constrain the particles made up of symmetrical shapes? and furthermore, how would I get them to morph into another shape? Is it even possile in particular? All this would be in 2d of course. Thanks a lot.

oh ant btw an example sort of simialr is this: http://www.nextlimit.com/cgi-bin/showvideo.pl?movie=phantom_dance.mov&width...

of course not to that extreme, just imagine it being 2d with square particles.

To emit particles in a certan shape, check out the "Layer Emitter".

It's not possible to morph shape so that the particles actually move into new positions, but you can let them die and then have new particles born in a new shape. Not the same thing...

Thanks, is it possible to precomp an alpha morph and assigning the particles to it to mimic such an effect?

heres a better example of what I'm aiming for http://www.profoundeffects.com/products/gakpak/gallery/footage/waves_blocks...

[Billys] "is it possible to precomp an alpha morph and assigning the particles to it to mimic such an effect? "

Yes. And there are two sampling methods for the alpha: At Current Time and At Particle Birth.

The only problem I'm having now is trying to constrain the particles to form the various geometric shapes. I've consulted the manual but with no luck. I'm trying to confine the particles using walls on an alpha mode. Do I have to contruct it like the floor bounce where I have to set up walls in 3d? http://www.flash4all.de/start.htm These 2d shuffling tiles is similar to what I'm trying to achieve, except mine are all symmetrical and shuffle into different shapes. Thanks again, I should have been more specific to begin with, sorry.
