Polygon culling is disabled by default. To enable or disable culling, use the enable() and disable() methods with the argument gl.CULL_FACE.
gl.enable(gl.CULL_FACE); gl.cullFace(gl.FRONT_AND_BACK);
To check the current cull face mode, query the CULL_FACE_MODE constant.
gl.getParameter(gl.CULL_FACE_MODE) === gl.FRONT_AND_BACK; // true
