WebGL2RenderingContext.endQuery()

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

Syntax

void gl.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 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.

Examples

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

// ...

gl.endQuery(gl.ANY_SAMPLES_PASSED);
