WebGL2RenderingContext: getInternalformatParameter() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨September 2021⁩.

Note: This feature is available in Web Workers.

The WebGL2RenderingContext.getInternalformatParameter() method of the WebGL 2 API returns information about implementation-dependent support for internal formats.

Syntax

js
getInternalformatParameter(target, internalformat, pname)

Parameters

target

A GLenum specifying the target renderbuffer object. Possible values:

gl.RENDERBUFFER

Buffer data storage for single images in a renderable internal format.

internalformat

A GLenum specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).

pname

A GLenum specifying the type of information to query. Possible values:

gl.SAMPLES

Returns an Int32Array containing sample counts supported for internalformat in descending order.

Return value

Depends on the requested information (as specified with pname). It is an Int32Array if pname is gl.SAMPLES.

Examples

js
const samples = gl.getInternalformatParameter(
  gl.RENDERBUFFER,
  gl.RGBA8,
  gl.SAMPLES,
);
