Number

WebGL extension #NN

Dependencies

Written against the WebGL API 1.0 specification.

Promoted to core and no longer available as an extension in WebGL API 2.0 specification.

Overview

This extension exposes the OES_depth24 functionality to WebGL.

There are no WebGL-specific behavioral changes.

Consult the above extension for documentation, issues and new functions and enumerants.

When this extension is enabled:

IDL

[Exposed=(Window,Worker), LegacyNoInterfaceObject]
interface OES_depth24 {
  const GLenum DEPTH_COMPONENT24_OES = 0x81A6;
};

Sample Code

        var extension = gl.getExtension('OES_depth24');
        if(extension !=== null){
            var depth = gl.createRenderbuffer();
            gl.bindRenderbuffer(gl.RENDERBUFFER, depth);
            gl.renderbufferStorage(gl.RENDERBUFFER, extension.DEPTH_COMPONENT24_OES, 128, 128);
            gl.bindRenderbuffer(gl.RENDERBUFFER, null);

            var fbo = gl.createFramebuffer();
            gl.bindFramebuffer(gl.FRAMEBUFFER, fbo);
            gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.DEPTH_ATTACHMENT, gl.RENDERBUFFER, depth);
            
            var fboStatus = gl.checkFramebufferStatus(gl.FRAMEBUFFER);
            console.assert(fboStatus == gl.FRAMEBUFFER_COMPLETE, 'Framebuffer is not complete');

            gl.bindFramebuffer(gl.FRAMEBUFFER, null);
            console.assert(gl.getError() == gl.NO_ERROR, 'A GL error occured');
        }
