The 'function1' function returns the result of a Function1 using just
one of the arguments given to the function2. The function1 is specified
as value1 or value2, depending on which argument it is to be evaluated
with. E.g.:
<name>
{
type function1;
value2 table
(
(0.00 (0 0 0))
(0.35 (0 0 1))
(0.71 (0 0 0))
);
}
The 'product' function returns the product of two independent
Function1-s of the two input arguments, again specified as value1 and
value2. For example, to scale a table of vectors in the first argument
with a ramp in the second argument:
<name>
{
type product;
value1<vector> table
(
(0.00 (0 0 0))
(0.25 (1 0 0))
(0.50 (0 0 0))
);
value2<scalar>
{
type linearRamp;
start 1;
duration 4;
}
}
Note that only one type specification (the <vector>/<scalar>/... part)
is needed in general for the value entries, and no type specifications
are needed if the function is scalar.
The 'radial' function returns a Function1 of the magnitude of the
two-dimensional vector with components equal to the input arguments.
E.g.:
<name>
{
type radial;
value table
(
(0.00 (0 0 0))
(0.35 (0 0 1))
(0.71 (0 0 0))
);
}
