The WebGL2RenderingContext.endQuery()
method of the WebGL 2 API marks the end of a given query target.
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.
None (undefined
).
const query = gl.createQuery();
gl.beginQuery(gl.ANY_SAMPLES_PASSED, query);
// â¦
gl.endQuery(gl.ANY_SAMPLES_PASSED);
