getQuery(target, pname)
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.
js
const currentQuery = gl.getQuery(gl.ANY_SAMPLES_PASSED, gl.CURRENT_QUERY);
