EXTDisjointTimerQuery class
The EXT_disjoint_timer_query extension is part of the WebGL API
and provides a way to measure the duration of a set of GL
commands, without stalling the rendering pipeline.
WebGL extensions are available using the
WebGLRenderingContext.getExtension() method. For more
information, see also Using Extensions in the WebGL tutorial.
Note: This extension should be available in WebGL1 contexts
only. EXT_disjoint_timer_query_webgl2 is available in WebGL 2
contexts .
In WebGL 2, the getQueryObject was renamed to
getQueryParameter.
In WebGL 2, other queries (such as occlusion queries and
primitive queries) are possible using WebGLQuery objects.
