`mix()`

Function in Builtins

mix(a, b, t): linear interpolation a + t·(b − a), component-wise, keyed by a.

import { mix } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

function mix<K extends FloatKey | Float64Key>(
  a: ReadonlyNode<K>,
  b: NoInfer<ArithArg<K>>,
  t: ReadonlyNode<'f32'> | number,
): Node<K>;
function mix(
  a: number,
  b: ReadonlyNode<'f32'> | number,
  t: ReadonlyNode<'f32'> | number,
): Node<'f32'>;

Parameters

a ReadonlyNode<K>
b NoInfer<ArithArg<K>>
t ReadonlyNode<'f32'> | number

Return value

Node<K>

Description

A t outside [0, 1] extrapolates; pass t through clamp or smoothstep when the result must stay within the a..b range.

Examples

Example

import { fn, mix, vec3, f32T } from 'typeshade'

const blend = fn('blend', { t: f32T }, ({ t }) => mix(vec3(0, 0, 0), vec3(1, 1, 1), t))

Targets

Target	Support	Notes
WGSL (WebGPU)	Supported	`mix(a, b, t)`. Over `f64` operands the fp64 pass rewrites it into its `df64` helper.
GLSL ES 3.00 (WebGL2)	Supported	`mix(a, b, t)`. Over `f64` operands the fp64 pass rewrites it into its `df64` helper.
CPU oracle	Supported	Evaluated in f64 by the oracle.
