mix — linearly interpolate between two values
genType mix(
|
genType x, |
| genType y, | |
genType a); |
genType mix(
|
genType x, |
| genType y, | |
float a); |
genType mix(
|
genType x, |
| genType y, | |
genBType a); |
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.
mix performs a linear interpolation between x
and y using a to weight between them. The return value
is computed as follows:
.
For the variants of mix where a is genBType,
elements for which a[i] is false, the result for that
element is taken from x, and where a[i] is
true, it will be taken from y. 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.
