MIX(3G)

NAME
mix - linearly interpolate between two values

DECLARATION

genType mix(genType x, genType y, genType a);

genType mix(genType x, genType y, float a);

genDType mix(genDType x, genDType y, genDType a);

genDType mix(genDType x, genDType y, double a);

genType mix(genType x, genType y, genBType a);

genDType mix(genDType x, genDType y, genBType a);

genIType mix(genIType x, genIType y, genBType a);

genUType mix(genUType x, genUType y, genBType a);

genBType mix(genBType x, genBType y, genBType a);

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.
