`vec4`

Function

Builds a vec4 from four scalars, a vec3 and a scalar, a vec2 and two scalars, or broadcasts a single scalar to all four components.

The signature and the sentence under each name are the compiler's own text at commit 26de7be8.

Syntax

declare function vec4<T = f32>(): VecFor4<T>
declare function vec4<T = f32>(x: number, y: number, z: number, w: number): VecFor4<T>
declare function vec4<T = f32>(v: vec3, w: number): VecFor4<T>
declare function vec4<T = f32>(v: vec2, z: number, w: number): VecFor4<T>
declare function vec4<T = f32>(x: number, v: vec2, w: number): VecFor4<T>
declare function vec4<T = f32>(x: number, y: number, v: vec2): VecFor4<T>
declare function vec4<T = f32>(x: number, v: vec3): VecFor4<T>
declare function vec4<T = f32>(a: vec2, b: vec2): VecFor4<T>
declare function vec4<T = f32>(scalar: number): VecFor4<T>
declare function vec4<T = f32>(v: vec4): VecFor4<T>
declare function vec4<T>(x: bool, y: bool, z: bool, w: bool): VecFor4<T>
declare function vec4<T>(scalar: bool): VecFor4<T>
declare function vec4<T = f32>(v: vec4i): VecFor4<T>
declare function vec4<T = f32>(v: vec4u): VecFor4<T>
declare function vec4<T = f32>(v: vec4b): VecFor4<T>
declare function vec4(v: vec4f64): vec4

A number in a parameter or a return position is the scalar slot. The ambient file declares a GPU scalar as a branded number whose brand is optional, so a literal and any branded scalar both fill it.

type f32 = number & { readonly [f32Tag]?: true }

A declaration you write still needs a width, and a bare number on a field or a parameter is refused; the TypeScript constructs page carries that row with the compiler's own message.

A signature may name a type the ambient file declares for its own use. These are those declarations.

VecFor4: type VecFor4<T> = VecElemOf<T, vec4u, vec4i, vec4f64, vec4b, vec4>
