Metaball effect

[electrichead]

Hi,

 

I was wondering if there is any help out there to create a metaball effect with two 2D circles. I am using Raphael to create the 2D shapes. Is this something that needs to be done within Raphael?

 

The effect I am going for is that there are a bunch of indicators moving vertically down a line at varying speeds. When they get close enough, I would like to animate them with a metaball effect so that the circles merge together and a number is displayed to show how many are in the cluster.

 

Is there any help out there to construct something like this? The bezier plugin only does tweening "along a bezier path," if I am not mistaken - it won't do a shape tween using beziers?

Not really sure how you would accomplish all that. Perhaps one of our community members will be willing to lend a hand.

Maybe you could use this as a starting point: http://jsdo.it/yokotak0527/75dO

Thank you for the replies. I am currently trying to use the algorithms at the link above (not fully in English) and this link: http://www.themaninblue.com/experiment/Blobular/

 

I'll post if I make any headway.
