WebGL2RenderingContext: endQuery() method

Available in workers

The WebGL2RenderingContext.endQuery() method of the WebGL 2 API marks the end of a given query target.

Syntax

endQuery(target)

Parameters

• target
  • : A GLenum specifying the target of the query. Possible values:
    • gl.ANY_SAMPLES_PASSED
      • : Specifies an occlusion query: these queries detect whether an object is visible (whether the scoped drawing commands pass the depth test and if so, how many samples pass).
    • gl.ANY_SAMPLES_PASSED_CONSERVATIVE
      • : Same as above, but less accurate and faster version.
    • gl.TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN
      • : Number of primitives that are written to transform feedback buffers.

Return value

None (undefined).

Examples

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

// …

gl.endQuery(gl.ANY_SAMPLES_PASSED);
