WebGLRenderingContext.depthRange()

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

Syntax

void gl.depthRange(zNear, zFar);

Parameters

zNear
A 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 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.

Examples

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]
