One can create spiraling motions for particles using expressions. This method propagates a local up vector for the curl so that the twist direction does not go through pole flipping as the particle changes direction.
Here is the vein brush from my unfold presentation, along with help on creating brush presets.
As promised here are the scene files from my Unfold presentation along with some brief descriptions.
I've modified the roman candle scene in my previous post to use lights positioned at particle locations for illumination, along with further refinements.
Here is a simple example that uses Maya nParticles and Fluids to simulate a roman candle.
One can use nParticles to create a jiggling Jello substance that can be sliced using an nConstraint with breakable bonds. The workflow is relatively quick and easy.
The trail of a torpedo is tricky to do because it combines fluid dynamics, surface and volume rendering as well as fog and light scattering.
I have put together a talk on emergent phenomena in Maya for Siggraph that one can currently view on the area. here are some of the scene files and scripts mentioned in that talk.
Emergence is a fascinating phenomenon where complexity can emerge through iteration of simple rules or processes. One of the most dramatic illustrations of emergence is the Mandelbrot set where seemingly endless structure and detail arise when iterating on a very simple equation (zn+1 = zn2 + c). I had a little fun and implemented a Mandelbrot texture totally inside a MEL expression. **WARNING: LOTS of hires images ahead...
With particle emission into a fluid in Maya2011 one can create natural looking large waterfalls.
