(1/3 of the angle) from the X axis to the Y axis, you'd set the Y value to twice
that of the X value. For example, X=0.2 and Y=0.4, or X=0.5 and Y=1.0.
Divergence Defines the range of variation (in degrees) for spin-axis orientation.
The actual deviation is calculated at random within this range. Unavailable
for the Random 3D option. Default=0. Range=0 to 180.
Uniqueness group
The Uniqueness setting affects the randomization of spin rate variation, spin
axis with the Random 3D option, and Divergence with the other options.
Seed Specifies a randomization value.
New Calculates a new seed using a randomization formula.
Scale Operator
Particle View on page 2811 > Click a Scale operator in an event or add a Scale
operator to the particle system and then select it.
The Scale operator lets you set and animate particle size during an event, with
optional random variation. Options for how scaling and animation are applied
give this operator a great deal of flexibility.
Procedures
Example: To animate particle scale:
This procedure gives an overview of animating particles to grow for 30 frames,
remain at full size for the next 30 frames, and then shrink for 30 frames. It
also gives an option for having the particles pulsate in size during the middle
period. To follow this procedure, you should be familiar with the basic usage
of Particle Flow and Track View.
1 Set up a default Particle Flow system. Set the Shape operator to Sphere,
and set the Display operator to Geometry.
2 Add a Send Out test to Event 01.
3 Add a new Scale operator to the event display, creating a new event. Set
the new event's Display operator to Geometry, and make sure it's a
different color than the one in Event 01.
4 Wire the Send Out test in Event 01 to Event 02.
