WebGL 2.0 草案[1]出来了,看来 WebGL 工作组的所有工作,包括 * WebGL 1.0 规范/WebGL 2.0 草案 * WebGL 扩展 * WebGL 测试案例 都支持 GitHub[2] 提交 pull request,需要讨论的技术议题有公开邮件组[3] (OpenGL ES 好像就没有 :()。我不是对 GL 很熟悉,这个版本主要的新特性有: * 多重渲染目标(out vec4 fragData[N]) * 着色器语言升级为 GLSL ES 3.00(从 GLSL 3.3 改出来的,但是差很多,也 没有几何着色器) * 压缩纹理 * 新的 render-buffer 格式 * VAO * PBO * ... 欢迎专家带动讨论一下。个人的经验是 OpenGL 4.x 的规范比 OpenGLES 好 读,OpenGLES 看起来各种不严谨(不过 WebGL 是最差的 orz)。 最近 Khronos 北京也开始有各种活动,或许之后会来翻 OpenGLES 2.0 跟 WebGL,有兴趣的人可以加一下 QQ 群:295115370 Firefox 有一个实验性质的实现[4],不过我注意到他用的着色器好像不是 GLSL ES 3.00(这个版本没有 gl_FragData 了),另外,使用 WebGL2 的方法是: canvas.getContext("experimental-webgl2"); 那个 2 让人很不爽,不过草案也要求这样,参考讨论[5]。之后讨论一下。 [1] http://www.khronos.org/registry/webgl/specs/latest/2.0/ [2] http://www.khronos.org/webgl/wiki/Using_Github_To_Contribute [3] https://www.khronos.org/webgl/public-mailing-list/archives/ [4] https://wiki.mozilla.org/Platform/GFX/WebGL2 [5] https://www.khronos.org/webgl/public-mailing-list/archives/1310/msg00000.html 以上 Kenny -------- Original Message -------- Subject: [Public WebGL] First editor's draft of WebGL 2.0 available Date: Mon, 16 Sep 2013 10:07:49 -0700 From: Dean Jackson <dino@apple.com> To: public_webgl@khronos.org webgl <public_webgl@khronos.org> We're happy to announce that the first editor's draft of WebGL 2.0 was uploaded to github/khronos.org last Friday. http://www.khronos.org/registry/webgl/specs/latest/2.0/ There are plenty of missing sections, and TODOs, and errors we've already discovered, but it gives everyone a good idea of the API. If you're a github member, you can file typos/etc against: https://github.com/KhronosGroup/WebGL However, if the issue warrants broader discussion, it's probably best to email this mailing list. Again, this is an editor's draft - not an official release from the WebGL Working Group.
