我们的艺术家希望能够直接通过控制粒子的方式就获得近乎流体的效果。3dsmax的插件AfterBurn就是做这个的，可惜在Maya下仿佛没有足够好的类似插件，于是他们要求我做一个。类似于Digital Domain为了《绝密飞行》中的空中云团的那个效果，而DD用的是自己的Voxel Bee-itch。曾经尝试了RBF插值，LSS插值，最后还是用了metaball。

Our artist would like to get the fluid effect by controlling the particle system. The AfterBurn for 3dsmax could finish this task very well, but as I know there is no a similar one in Maya, they asked me whether I could fork another one. We want to make some VFX just like the cloud in "Stealth" from Digital Domain, they use their in-house particle tool named "Voxel Bee-itch". I have tried to interpolate particles by RBF, LSS, finally I decided to use metaball.
