WebGL2RenderingContext: getQueryParameter() 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.

The WebGL2RenderingContext.getQueryParameter() method of the WebGL 2 API returns parameter information of a WebGLQuery object.

getQueryParameter(query, pname)

A GLenum specifying which information to return. Possible values:

gl.QUERY_RESULT: Returns a GLuint containing the query result.
gl.QUERY_RESULT_AVAILABLE: Returns a GLboolean indicating whether or not a query result is available.

Depends on the pname parameter, either a GLuint or a GLboolean.

const query = gl.createQuery();
gl.beginQuery(gl.ANY_SAMPLES_PASSED, query);

const result = gl.getQueryParameter(query, gl.QUERY_RESULT);
