Mix
Constrain a value to lie between two further values
Declaration
float mix(float x, float y, float a)
vec2 mix(vec2 x, vec2 y, vec2 a)
vec3 mix(vec3 x, vec3 y, vec3 a)
vec4 mix(vec4 x, vec4 y, vec4 a)
vec2 mix(vec2 x, vec2 y, float a)
vec3 mix(vec3 x, vec3 y, float a)
vec4 mix(vec4 x, vec4 y, float 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×(1−a)+y×a.
