WebGLQuery - Web APIs | MDN
WebGLQuery Baseline Widely available
The WebGLQuery
interface is part of the WebGL 2 API and provides ways to asynchronously query for information. By default, occlusion queries and primitive queries are available.
Another kind of queries are disjoint timer queries, which allow you to measure performance and profiling of your GPU. Disjoint timer queries are available with the EXT_disjoint_timer_query
extension only.
WebGLObject
WebGLQuery
When working with WebGLQuery
objects, the following methods of the WebGL2RenderingContext
are useful:
in this example, gl
must be a WebGL2RenderingContext
. WebGLQuery
objects are not available in WebGL 1.
const query = gl.createQuery();
