WebGL2RenderingContext: endQuery() method

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

Syntax

js

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

js

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

// …

gl.endQuery(gl.ANY_SAMPLES_PASSED);
