WEBGL_depth_texture 扩展属于 WebGL API and defines 2D depth and depth-stencil textures.

WebGL extensions are available using the WebGLRenderingContext.getExtension() method. For more information, see also 使用扩展在 WebGL 教程 .

可用性： 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 .

常量

This extension adds a new constant:

ext.UNSIGNED_INT_24_8_WEBGL

Extended methods

This extension extends WebGLRenderingContext.texImage2D() :

format and internalformat parameters now accept gl.DEPTH_COMPONENT and gl.DEPTH_STENCIL .
type parameter now accepts gl.UNSIGNED_SHORT , gl.UNSIGNED_INT ，和 ext.UNSIGNED_INT_24_8_WEBGL .
pixels parameter now accepts an ArrayBufferView 类型 Uint16Array and Uint32Array .

This extension extends WebGLRenderingContext.framebufferTexture2D() :

attachment parameter now accepts gl.DEPTH_STENCIL_ATTACHMENT .

Incorrectly stated as the target parameter in the specification, see https://www.khronos.org/bugzilla/show_bug.cgi?id=674 .

范例

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);
