WebGL2RenderingContext: createQuery() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

Note: This feature is available in Web Workers.

The WebGL2RenderingContext.createQuery() method of the WebGL 2 API creates and initializes WebGLQuery objects, which provide ways to asynchronously query for information.

In this article

Syntax

js
createQuery()

Parameters

None.

Return value

A WebGLQuery object.

Examples

gl must be a WebGL2RenderingContext. WebGLQuery objects are not available in WebGL 1.

js
const query = gl.createQuery();
