WebGLRenderingContext: depthRange() method

{{APIRef("WebGL")}}{{AvailableInWorkers}}

The WebGLRenderingContext.depthRange() method of the WebGL API specifies the depth range mapping from normalized device coordinates to window or viewport coordinates.

Syntax

depthRange(zNear, zFar)

Parameters

• zNear
  • : A {{domxref("WebGL_API/Types", "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.
• zFar
  • : A {{domxref("WebGL_API/Types", "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.

Return value

None ({{jsxref("undefined")}}).

Examples

gl.depthRange(0.2, 0.6);

To check the current depth range, query the DEPTH_RANGE constant which returns a {{jsxref("Float32Array")}}

gl.getParameter(gl.DEPTH_RANGE);
// Float32Array[0.2, 0.6]
