WEBGL_depth_texture extension

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.

See full compatibility

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.

Note: This extension is only available to WebGL1 contexts. In WebGL2, the functionality of this extension is available on the WebGL2 context by default. The constant in WebGL2 is gl.UNSIGNED_INT_24_8.

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 and internalformat parameters now accept gl.DEPTH_COMPONENT and gl.DEPTH_STENCIL.
The type parameter now accepts gl.UNSIGNED_SHORT, gl.UNSIGNED_INT, and ext.UNSIGNED_INT_24_8_WEBGL.
The pixels parameter now accepts a Uint16Array or a Uint32Array object.

This extension extends WebGLRenderingContext.framebufferTexture2D():

The attachment parameter now accepts gl.DEPTH_STENCIL_ATTACHMENT.

Examples

const 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,
);
