`reflect`

Function

Reflects the incident vector i about the normal n: i - 2 * dot(n, i) * n.

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

Syntax

declare function reflect<V extends vec2 | vec3 | vec4>(a0: V, a1: V): V
declare function reflect<T extends Numeric>(a0: T, a1: T): T

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

Numeric: type Numeric = number | vec2 | vec3 | vec4 | vec2i | vec3i | vec4i | vec2u | vec3u | vec4u

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.

VT

n should be normalized. Same shape in, same shape out.
