Parameters
-
x
-
Specify the start of the range in which to interpolate.
-
y
-
Specify the end of the range in which to interpolate.
-
a
-
Specify the value to use to interpolate between x
and y
.
Description
mix
performs a linear interpolation between x
and y
using a
to weight between them. The return value is computed as $x \times (1 - a) + y \times a$.
The variants of mix
where a
is genBType
select which vector each returned component comes from. For a component of a
that is false, the corresponding component of x
is returned. For a component of a
that is true, the corresponding component of y
is returned. Components of x
and y
that are not selected are allowed to be invalid floating-point values and will have no effect on the results.
