smoothstep

Syntax

declare function smoothstep<V extends vec2 | vec3 | vec4>(a0: V, a1: V, a2: V): V
declare function smoothstep<P0 extends number, P1 extends number, P2 extends number>(a0: P0, a1: P1, a2: P2): ([P0] extends [boolean] ? bool : typeof f32Tag extends keyof P0 ? f32 : typeof i32Tag extends keyof P0 ? i32 : typeof u32Tag extends keyof P0 ? u32 : typeof f64Tag extends keyof P0 ? f64 : ([P1] extends [boolean] ? bool : typeof f32Tag extends keyof P1 ? f32 : typeof i32Tag extends keyof P1 ? i32 : typeof u32Tag extends keyof P1 ? u32 : typeof f64Tag extends keyof P1 ? f64 : ([P2] extends [boolean] ? bool : typeof f32Tag extends keyof P2 ? f32 : typeof i32Tag extends keyof P2 ? i32 : typeof u32Tag extends keyof P2 ? u32 : typeof f64Tag extends keyof P2 ? f64 : number)))
declare function smoothstep<T extends Numeric>(a0: T, a1: T, a2: T): T

Parameters

A parameter named by position (a0, a1) carries a name the ambient file generates. A call passes its arguments in order and names none of them.

• a0 VP0T
• a1 VP1T
• a2 VP2T

Return value

V([P0] extends [boolean] ? bool : typeof f32Tag extends keyof P0 ? f32 : typeof i32Tag extends keyof P0 ? i32 : typeof u32Tag extends keyof P0 ? u32 : typeof f64Tag extends keyof P0 ? f64 : ([P1] extends [boolean] ? bool : typeof f32Tag extends keyof P1 ? f32 : typeof i32Tag extends keyof P1 ? i32 : typeof u32Tag extends keyof P1 ? u32 : typeof f64Tag extends keyof P1 ? f64 : ([P2] extends [boolean] ? bool : typeof f32Tag extends keyof P2 ? f32 : typeof i32Tag extends keyof P2 ? i32 : typeof u32Tag extends keyof P2 ? u32 : typeof f64Tag extends keyof P2 ? f64 : number)))T

Description

Returns 0 when x is less than or equal to edge0, 1 when greater than or equal to edge1, and interpolates smoothly between. Componentwise over vectors.

Evaluated in f64 by the CPU oracle.
