支持 OpenGL 下的细分网格的 Unigine Heaven 即将发布
Posted by Michael Larabel on May 18, 2010
We have heard from Denis Shergin, the CEO of Unigine Corp, that an update to Unigine Heaven is imminent. Heaven is their beautiful but demanding technology demo / benchmark that launched last year with a DirectX 11.0 renderer and then in March reached version 2.0 and was released for Linux (finally) with an OpenGL renderer.
我们已经从 Unigine CEO 丹尼斯舍尔金 那里听到 Unigine Heaven 即将更新的消息。Heaven 是一个很漂亮的且硬件要求颇高的演示/基准测试，他去年推出了支持 DirectX 11.0渲染的版本，然后在3月份为 Linux 发布了支持 OpenGL 渲染的 2.0 版（最新版）。
The Linux release of Unigine Heaven with its OpenGL 3.x renderer was postponed many times since the Heaven 1.0 release in October due to ATI Catalyst driver problems. ATI was the first to offer a DirectX 11.0 graphics processor -- the ATI Radeon HD 5000 "Evergreen" series -- that has a hardware tesselator, but their Linux drivers always wound up being too buggy, so Unigine Corp kept pushing back the release. In March the proprietary ATI Linux driver started getting better, but Unigine Corp wound up shipping a release with the OpenGL tessellation support disabled by default even though NVIDIA now has out their GeForce GTX 400 "Fermi" series that are DX11 capable and support this functionality.
Linux 下的使用 OpenGL 3.x 渲染的 Unigine Heaven 多次推迟发布，早在 10月份 Heaven 1.0 发布的时候也遇到过 ATI 驱动产生的问题。虽然 ATI 的 Radeon HD 5000 "Evergreen" 系列首次支持 DirectX 11 ，他具有硬件处理细分曲面的能力，但是他们的 Linux 驱动的 bug 却很多，以至于 Unigine 一直不能发布。3月份，ATI 的 Linux 驱动质量开始好转，但是 Unigine 却禁用了 OpenGL 下的细分曲面，尽管 NVIDIA 支持DX11 和细分曲面的 GeForce GTX 400 “Fermi” 已经发布。
注：Unigine 曾表示，当 GTX 400 发布时，他们就在 Demo 中打开对 OpenGL 的细分曲面的支持。
Unigine Heaven 2.1 is expected to be released in the coming days and it will offer OpenGL hardware tessellation support. However, we are told by Unigine Corp that the ATI Catalyst drivers still are too broken to work there, which means it will really just run well with a NVIDIA Fermi GPU and their proprietary driver. It wasn't shared, however, whether this Heaven update is hooking into the official tessellation support found in the API for OpenGL 4.0 or what approach they are taking. It's also not known if this 2.1 update will offer any other significant changes beyond the tessellation capabilities.
未来几天即将发布的 Unigine Heaven 2.1 预计将会支持OpenGL 下的硬件细分曲面。然而，Unigine 公司称 ATI 的 Catalyst 驱动仍然问题重重，这意味着他可能只能运行在 NVIDIA Fermi 的 GPU 上。我们不知到 Heaven 是否会支持 OpenGL ，也不知道他们会不会想其他的方法来支持细分曲面。我们不知到 2.1 会不会真的支持细分曲面，也不知到究竟会有什么重大变化。
Unigine Heaven can be run through the Phoronix Test Suite along with dozens of other OpenGL benchmarks.
Unigine 可以运行在 Phoronix 提供十几个 OpenGL 的基准测试的工具上。

从 系统监视器上看，演示运行时只有一个核心的负载比较高，但没有达到100%。显卡的温度从50度上升到60度。[/size]
