WEBGL_depth_texture
The WEBGL_depth_texture
extension is part of the WebGL API and defines 2D depth and depth-stencil textures.
WebGL extensions are available using the WebGLRenderingContext.getExtension()
method. For more information, see also Using Extensions in the WebGL tutorial.
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 anArrayBufferView
of typeUint16Array
andUint32Array
.
This extension extends WebGLRenderingContext.framebufferTexture2D()
:
- The
attachment
parameter now acceptsgl.DEPTH_STENCIL_ATTACHMENT
.
Note: Incorrectly stated as the target
parameter in the specification, see https://www.khronos.org/bugzilla/show_bug.cgi?id=674.
Examples
var ext = gl.getExtension('WEBGL_depth_texture');
gl.texImage2D(gl.TEXTURE_2D, 0, gl.DEPTH_COMPONENT, 512, 512, 0, gl.DEPTH_COMPONENT, gl.UNSIGNED_SHORT, null);
