Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The WEBGL_depth_texture

Constants
This extension adds a new constant:
ext.UNSIGNED_INT_24_8_WEBGL
-
Unsigned integer type for 24-bit depth texture data.
Extended methods
This extension extends WebGLRenderingContext.texImage2D()
:
- The
format
andinternalformat
parameters now acceptgl.DEPTH_COMPONENT
andgl.DEPTH_STENCIL
. - The
type
parameter now acceptsgl.UNSIGNED_SHORT
,gl.UNSIGNED_INT
, andext.UNSIGNED_INT_24_8_WEBGL
. - The
pixels
parameter now accepts aUint16Array
or aUint32Array
object.
This extension extends WebGLRenderingContext.framebufferTexture2D()
:
- The
attachment
parameter now acceptsgl.DEPTH_STENCIL_ATTACHMENT
.
