This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.getInternalformatParameter() method of the WebGL 2 API returns information about implementation-dependent support for internal formats.
any gl.getInternalformatParameter(target, internalformat, pname);
targetGlenum specifying the target renderbuffer object. Possible values: gl.RENDERBUFFER: Buffer data storage for single images in a renderable internal format.internalformatGLenum specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).pnameGLenum specifying the type of information to query. Possible values: gl.SAMPLES: Returns a Int32Array containing sample counts supported for internalformat in descending order.Depends on the requested information (as specified with pname). It is an Int32Array if pname is gl.SAMPLES.
var samples = gl.getInternalformatParameter(gl.RENDERBUFFER,
gl.RGBA8, gl.SAMPLES);
