@luma.gl/webgl/constants

From-v9.3

info

In luma.gl versions earlier than v9.3, these exports were provided by @luma.gl/constants. Use @luma.gl/webgl/constants going forward.

Use this entry point when you need the raw numeric WebGL enums that luma.gl still uses internally for WebGL interop.

import {GL} from '@luma.gl/webgl/constants';
import type {GLParameters, GLSamplerParameters} from '@luma.gl/webgl/constants';

Exports​

  • GL: numeric WebGL enum object covering WebGL 2 and supported extension constants.
  • WebGL enum-related TypeScript types such as GLParameters, GLExtensions, GLTextureTarget, GLUniformType, and related helper types.

When To Use This​

  • When calling raw WebGL APIs on WebGL2RenderingContext.
  • When translating between luma.gl abstractions and numeric WebGL parameters.
  • When writing low-level WebGL helpers, tests, or debugging tools.

Preferred API Style​

Most luma.gl application APIs use typed WebGPU-style strings rather than numeric WebGL enums. Prefer those higher-level string APIs unless you are specifically interfacing with raw WebGL.
