degToRadfunction

degToRad

Converts degrees to radians for custom scene math. Use it when a shader uniform, animation helper, or math API expects radians while your input is in degrees.

Import

TypeScript
1
import { degToRad } from "vgpu/scene";

Signature

TypeScript
1
declare function degToRad(deg: number): number;

Parameters

ParamTypeRequiredDefaultNotes
degnumber✔—Angle in degrees. Positive, negative, fractional, Infinity, and NaN are passed through JavaScript number arithmetic.

Returns: number — deg * Math.PI / 180, suitable for Math.sin, Math.cos, matrix helpers, or shader uniforms that expect radians. Throws: None.

const quarterTurn = degToRad(90);
const rotation = { sinAngle: Math.sin(quarterTurn), cosAngle: Math.cos(quarterTurn) };

Notes

  • Public camera helpers in vgpu/scene accept degrees for field-of-view values; do not convert PerspectiveCameraOptions.fov yourself.
  • Use degToRad for custom transforms and CPU-side uniform values that explicitly need radians.
  • See also: perspectiveCamera, orbit.
