This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.endQuery() method of the WebGL 2 API marks the end of a given query target.
void gl.endQuery(target);
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 above, but less accurate and faster version.gl.TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN: Number of primitives that are written to transform feedback buffers.None.
var query = gl.createQuery(); gl.beginQuery(gl.ANY_SAMPLES_PASSED, query); // ... gl.endQuery(gl.ANY_SAMPLES_PASSED);
