... if you don't mind me asking?

Mmm..."meatballs"; 'cos the Japanese inventor couldn't...

-Understand the history but never use them. just curious.

Thanks.

how do you animate it?

... some month ago, I was modeling a freezed splash of water, it was verry easy to do with metaballs...

Cool. I see, that's logical.

Thanks!

I guess it could be done with hypervoxels or metaballs

quote " ... there a different ways to animate, in my last work I used to morph some metaballs, and other I was working with only the points I was generating from the metaballs, using hypervoxels and dynamics to get them animated..."



That's not really animating the metaballs though, as the blobbing together effect can only happen in modeller where it can't be rendered.

So, by using hypervoxels, you're just recreating a metaball-like effect in layout. and by morphing them, you're morphing the frozen metaball, which is just a tripled mesh once taken to layout, not a metaball as it exists in modeller

they are not unusable

No, not in modeller to give you a guide where to put some points, but once in layout they are directly unusable for animation.
I'm not trying to be pedantic, it's just always irritated me that metaballs can't be used this way, as the concept of skinning a dynamically generated mesh over animated points would actually be very useful.

I was hoping for a moment that maybe you'd discovered the .p file that lets you animate them in layout.

It was done with Metaballs by an UK company...not done in LW though... You can see more about it on the 3DWorld magazine, the one that has a Dino on the cover.

Never said it couldnt, just confirmed that it was made with Metaballs and that they are still usefull :D

I stand corrected!!

Wow that's a bit embarrassing I've fiddled with them in the past and never got them to do anything in layout. Cheers for that.

The most recent use of metaballs I've seen in production is for the ice Frozone created in The Incredibles.

yep Sil3, unfortunatly I have that magazine.

The last time i used metaballs was.. 1996? in Strata Studio pro to make this devil character that brought the computer to its knees when merging them all into a cohesive mesh.

Back in 2005 I did a test with metaballs. This animation was driven by a procedural only.

This quicktime video is 2mb's @120 frames. I had to rerender this test animation as indeo is no longer available for a codec.

Cool, but you could do that without metaballs.

Only if you haven't seen Spider-Man 3 (and after the 'evil jazz hands' segment I really don't blame you if you missed it or are blocking the trauma from your memory). The Venom 'alien goo' was made using Houdini's metaballs, which can apparently be animated using a stretchy spline of some sort. Every twitch and wave had to be keyed by hand as a result, and one tech said they were working on the final scene (death of Venom) until just two weeks before release. Cool stuff.

That being said, has anyone considered using them for an object replacement sequence? This would be another way to 'animate' them in LW I would think.

Yeah, but where's the fun in that. ;)

I used them in a protein animation. Loaded in the protein from a data base, cleaned out some of the excessive points and used meta balls. Worked great.

Being somewhat lysdexic at times I often read these as meatballs... mmmmmmm... meatballs. :)

Yeah, indeed where is the fun? OK, I'm getting the drift. I thought they were a little outdated and wow about ten years ago bring surpassed by pfx?

-No, you're not dyslexic/lysdexic; the guy who invented them was. It's told that he called them meatballs but being Japanese... is-ha-meata-ball. So the story goes.
