Baseline Widely available
Note: This feature is available in Web Workers.
The WebGL2RenderingContext.getQuery() method of the WebGL 2 API returns the currently active WebGLQuery for the target, or null.
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.
pname
A GLenum specifying the query object target. Must be gl.CURRENT_QUERY.
A WebGLQuery object.
const currentQuery = gl.getQuery(gl.ANY_SAMPLES_PASSED, gl.CURRENT_QUERY);
