Is anyone making or has a technique for making animated splatters. I think it would be a good IPAS, it could be used for everything from blood splatters flying out of a victim to a raindrop causing a splash in a pool. It shouldn't be difficult, it's just a particle system. – Neil

Neil, >> Is anyone making or has a technique for making animated splatters. << I've used hand-lofted and morphed splatter shapes before for paint splatters (see Siggraph '93 (or '92) reel under the name CEC/3 Space). Nowadays I'd probably try a combo of metaballs and dynamics (or hand animated).

I have used spurt from Yost with an inverted gravity factor to simulate rain splatters. Works well for water (I have hade best results using a sphere emmitter), but blood has a thicker consistency. I would recommend a metaballs modeler for simulating blood, oil or mercury effects.

Thanks Martin, I've tried lofted splatters, but they never seem to come out right. I guess I'll have to invest in Metaballs in the near future. – Neil

I would suggest using a combination of metaballs and a dynamics package. Alternatively, there are a couple of "dynamics" scripts floating around here. They should give you the kind of control you need over the metaball reference spheres to achieve this effect.

Thank Danny, I'll look into a metaballs program. – Neil

Neil, >> Thanks Martin, I've tried lofted splatters, but they never seem to come out right. << they worked OK for me for very thick paint splats. Care must be taken in the lofting to ensure the vertex order makes sense – otherwise the splat may turn itself inside out or react in other unpredictable ways. >> I guess I'll have to invest in Metaballs in the near future. << there is nothing quite like them for certain type of effects.

Hi Neil, << Animated splatters..? >> Check out Peter's cool Spray.zip and associatde Hoser.zip in the scripts section of the library. jonas[adesk]

Thanks, I know about those scripts. I'm using them for a completely unrelated project right now, but maybe they will work for the splatter project if I use them along with Metaballs or Meterreyes. – Neil
