WebGLRenderingContext: cullFace() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The WebGLRenderingContext.cullFace() method of the WebGL API specifies whether or not front- and/or back-facing polygons can be culled.

Syntax

js
cullFace(mode)

Parameters

mode

A GLenum specifying whether front- or back-facing polygons are candidates for culling. The default value is gl.BACK. Possible values are:

  • gl.FRONT
  • gl.BACK
  • gl.FRONT_AND_BACK

Return value

None (undefined).

Examples

Polygon culling is disabled by default. To enable or disable culling, use the enable() and disable() methods with the argument gl.CULL_FACE.

js
gl.enable(gl.CULL_FACE);
gl.cullFace(gl.FRONT_AND_BACK);

To check the current cull face mode, query the CULL_FACE_MODE constant.

js
gl.getParameter(gl.CULL_FACE_MODE) === gl.FRONT_AND_BACK;
// true
