WebGLRenderingContext.cullFace()

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

Syntax

void gl.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.

Examples

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
