The WebGLRenderingContext.depthRange() method of the WebGL API specifies the depth range mapping from normalized device coordinates to window or viewport coordinates.
WebGLRenderingContext: depthRange() method
Syntax
js
depthRange(zNear, zFar)
Parameters
-
zNear -
A
GLclampfspecifying 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 tozFar. The default value is 0. -
zFar -
A
GLclampfspecifying 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 (undefined).
Examples
js
gl.depthRange(0.2, 0.6);
To check the current depth range, query the DEPTH_RANGE constant which returns a Float32Array
js
gl.getParameter(gl.DEPTH_RANGE);
// Float32Array[0.2, 0.6]
