The WebGLRenderingContext.clearDepth() method of the WebGL API specifies the clear value for the depth buffer.
This specifies what depth value to use when calling the clear() method. The value is clamped between 0 and 1.
void gl.clearDepth(depth);
depthGLclampf specifying the depth value used when the depth buffer is cleared. Default value: 1.None.
gl.clearDepth(0.5);
To get the current depth clear value, query the DEPTH_CLEAR_VALUE constant.
gl.getParameter(gl.DEPTH_CLEAR_VALUE); // 0.5
