• Spiral: Particles emerge from a spiral pattern. Using the onscreen controls (with the
Adjust Item tool), you can specify the size and location of the spiral. The Spiral shape
displays additional parameters.
• Wave: Particles emerge from a waveform. Using the onscreen controls (with the Adjust
Item tool) or the Start Point and End Point parameters in the Emitter Inspector, you
can specify the length and location of the wave. The Wave shape displays additional
parameters.
• Geometry: Particles emerge from the edge of a shape, defined by a spline object used
as the shape source. The Geometry shape displays additional parameters. The following
image on the right shows the shape that used as the emitter source. The image on the
left shows particles emerging from the edge of the shape source.
