COLLADA 是一种死格式吗？
我在网上读到很多关于 COLLADA 是一种死文件格式的思考？因为应用程序没有更新对其的支持等。这是真的吗？它最初被设计为一种几乎独立于应用程序的格式，所以我的问题分为两部分。这是死格式吗？如果是这样，目前接受的格式是什么，以最大限度地提高应用程序间开发（并与 OpenGL 应用程序一起使用）？
I've been reading lots of musings on the net that COLLADA is a dead file format? In that applications are not updating their support for it etc. Is this true? It was originally designed to be a format that could be almost application independant so my question is in 2 parts. Is it a dead format? And if so, what is the current accepted format to maximise inter-application development (and to use with OpenGL applications)?

大多数应用程序都支持 COLLADA，并且一直在宣布新的支持。
在 Twitter 上关注 COLLADA 以获取每日更新……还很遥远。
事实上很难跟踪。
顺便说一句，Khronos 刚刚发布了 COLLADA 参考卡。免费位于 http://www.khronos.org/files/collada_reference_card_1_4.pdf ，使其更易于实施。
仍然缺少的部分是一致性测试，以确保应用程序正确遵循规范，并且它最近已发布。
简而言之，期望改进的支持、更多的应用程序和更好的互操作性。可以肯定的是，COLLADA 是一项已发布的标准（而不是一项专有技术），因此它可以保留并安全地进行投资，因为它不受合并、破产、公司政策变化的影响
......。 ..
此外，我们正在重建 collada.org。有一个不完整的产品列表，以及一个供您提问的论坛。
Most applications are supporting COLLADA, new support is announced all the time.
Follow COLLADA on twitter to get daily updates... far to be dead.
Hard to keep track in fact.
BTW, Khronos just released the COLLADA reference card. free at http://www.khronos.org/files/collada_reference_card_1_4.pdf , making it easier to implement.
Still the missing piece was the conformance test, to make sure applications are correctly following the specification, and it has been released recently
In short, expect improved support, more applications, better interoperability. One thing for sure is COLLADA is a published standard, (as opposed to be a proprietary technology), so it is there to stay and safe to invest in as it is not impacted by mergers, bankruptcies, change in company policies...
...
also, we are in the process of rebuilding collada.org. There is an incomplete list of products , and a forum for your questions.
COLLADA 应该是生产内容时的中间格式。这就是为什么用于建模包的插件和库比用于 3d 引擎和库的插件和库多。
自定义 OpenGL 图形引擎倾向于使用自己的模型格式，因此它可以实现 COLLADA 中没有的新功能。
COLLADA was supposed to be an intermediate format while producing content. That is why there are more plugins and libraries for modeling packages than there are for 3d engines and libraries.
A custom OpenGL graphics engine will tend to use its own model format so it can implement new features that are not in COLLADA.
COLLADA 有很多中间件支持，所以我认为你不能说它已经死了。然而，它并没有像一些人所希望的那样成为统治一切的唯一格式。基本上，它是不同软件包之间 3D 资产交换的最佳通用中间立场，但它不太适合引擎内使用。
There's a lot of middle-ware support for COLLADA, so I don't think you can call it dead. However, it hasn't become The One Format To Rule Them All, as some was hoping for. Basically, it's the best common middle-ground for 3d-asset exchange between different software-packages, but it's not a very good fit for in-engine usage.
我对 COLLADA 格式的未来不太乐观。自规范 1.5 发布以来，没有发生任何事情。没有工具支持完整的 COLLADA 功能。
OpenCOLLADA 是一个很好的库，它现在可以帮助该格式保持活力，但这还不够。格式本身也应该随着时间的推移而改进。我尝试使用 COLLADA 的物理库，我能找到的唯一可以创建合理示例的工具是 Maya。而且并非没有额外的努力来安装插件等。大多数 COLLADA 导入程序不支持 1.5，当他们支持该版本时，他们不支持某些元素。 COLLADA 模型存储库服务器已关闭很长时间，很难找到可以使用的各种好的示例。
AutomationML格式使用COLLADA作为图形格式，这为工业用途的传播带来了可能性。但这个领域已经有一些强大的竞争对手，比如JT。
另一个问题是，COLLADA 在元素中支持 MathML，但在 MathML 作为格式进行改进期间，COLLADA 保持不变，无法使用新版本的 MathML 格式。
我喜欢 COLLADA 的想法，但由于缺乏支持和应用，它离它的目标还很远。
I am not really optimistic about the future of the COLLADA format. Nothing happened since the publication of specification 1.5. There is no tool which supports the complete COLLADA functionality.
OpenCOLLADA is a nice library which helps the format alive for now, but it is not enough. Format itself should improve through the time, too. I have tried to work with physics libraries of COLLADA, the only tool I can find to create a reasonable example was Maya. And not without extra effort to install plugins, etc. Most of the importers for COLLADA does not support 1.5, and when they support the version they do not support some of the elements. COLLADA model repository server is down for ages, it is difficult to find good examples with variety to work with.
AutomationML format uses COLLADA as graphic format, which brings the possibility to be spread for industrial usage. But there are already some strong competitors in this field like JT.
An extra problem, COLLADA supports MathML in element but during MathML improves as a format, COLLADA stays put and new versions of MathML format cannot be used.
I liked the idea of the COLLADA, but it is far away from its goals because of the lack of support and applications.
