The WebGLRenderingContext.depthRange() method of the WebGL API specifies the depth range mapping from normalized device coordinates to window or viewport coordinates.
depthRange(zNear, zFar)zNearA GLclampf specifying the mapping of the near clipping plane to window or viewport coordinates. Clamped to the range 0 to 1 and must be less than or equal to zFar. The default value is 0.
zFarA GLclampf specifying the mapping of the far clipping plane to window or viewport coordinates. Clamped to the range 0 to 1. The default value is 1.
None (undefined).
gl.depthRange(0.2, 0.6);To check the current depth range, query the DEPTH_RANGE constant which returns a Float32Array
gl.getParameter(gl.DEPTH_RANGE);
// Float32Array[0.2, 0.6]
