Outward opacity falloff
Top: None
Bottom: 100%
The falloff amount never makes the object less opaque than the value of the
Opacity spinner. For example, if Opacity were set to 50, and Falloff set to In,
the inner portions would remain at 50 percent opacity, and the Amt. spinner
would change the outer edges, until they became opaque at 100.
Operand
An operand is one of a set of objects upon which an operation such as
Boolean
on page 686 is to be done. The Boolean operation takes two operands: the first
operand is called operand A, and the second operand is called operand B.
Operator
In
Particle Flow on page 2713 , the operator is the basic element of the particle
system; you combine operators into
events on page 7770 to specify the particles'
characteristics over a given period of time. Operators let you describe particle
speed and direction, shape, surface properties, and more.
A list of all operators in Particle Flow is available in the
Operators topic on
page 2761 .
