The WebGL2RenderingContext.endQuery() method of the WebGL 2 API marks the end of a given query target.
endQuery(target)targetA GLenum specifying the target of the query. Possible values:
gl.ANY_SAMPLES_PASSEDSpecifies 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_CONSERVATIVESame as above, but less accurate and faster version.
gl.TRANSFORM_FEEDBACK_PRIMITIVES_WRITTENNumber of primitives that are written to transform feedback buffers.
None (undefined).
const query = gl.createQuery();
gl.beginQuery(gl.ANY_SAMPLES_PASSED, query);
// …
gl.endQuery(gl.ANY_SAMPLES_PASSED);
