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.
