`smoothstep()`

Function in Builtins

smoothstep(e0, e1, x): Hermite interpolation from 0 at x = e0 to 1 at x = e1, component-wise.

import { smoothstep } from 'typeshade'

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

Syntax

function smoothstep<K extends `vec${number}<f32>`>(
  e0: ReadonlyNode<K>,
  e1: ReadonlyNode<K>,
  x: ReadonlyNode<K>,
): Node<K>;
function smoothstep(
  e0: ReadonlyNode<'f32'> | number,
  e1: ReadonlyNode<'f32'> | number,
  x: ReadonlyNode<'f32'> | number,
): Node<'f32'>;

Parameters

e0 ReadonlyNode<K>
e1 ReadonlyNode<K>
x ReadonlyNode<K>

Return value

Node<K>

Description

WGSL requires all three arguments to have the same type, scalar or vector. The vector overload keeps the key of x; the scalar overload takes f32 nodes or JS numbers.

Targets

Target	Support	Notes
WGSL (WebGPU)	Supported	`smoothstep(e0, e1, x)`.
GLSL ES 3.00 (WebGL2)	Supported	`smoothstep(e0, e1, x)`.
CPU oracle	Supported	Evaluated in f64 by the oracle.
