This week at Game Developers Conference IBM will show a Linux based PS3 real-time rendering a complex (3 million triangle) urban landscape, at 1080p resolution, using only software rendering techniques (iRT).

Even though the PS3’s RSX is inaccessible under Linux the smart little system will reach out across the network and leverage multiple IBM QS20 blades to render the complex model, in real-time, with software based ray-tracing.  Using IBM’s scalable iRT rendering technology, the PS3 is able to decompose each frame into manageable work regions and dynamically distribute them to blades or other PS3s for rendering.  These regions are then further decomposed into sub-regions by the blade’s Cell processors and dynamically dispatched to the heavy lifting SPEs for rendering and image compression.  Finished encoded regions are then sent back to the PS3 for Cell accelerated decompression, compositing, and display.


Here is a resolution reduced (30MB) Quicktime movie of the demo.

Myself, Mark Nutter, and Joaquin Madruga will be on hand in the IBM booth to run the demonstration so stop by, introduce yourself, and swap some Cell programming stories.  Even though much has been made in the press about how difficult the Cell processors is to program, our team of three started with a couple white papers and in only three months created this renderer, the 3dsMax to BVH tree output tool chain, the display client, and the blade distribution framework using only the tools provided in the Cell SDK.  Actually we spent as much time trying to figure out how to preserve our 3dsMax models during export and create a good BVH tree as we did writing the Cell code.




在PS3 LINUX下，RSX不可用，用CELL软RENDERING

1080p，300万TRIANGLE

…………惊！

cell真猛啊

王道的IBM。

看起来有点像分布运算的概念啊,模拟地球指日可待:D

看清楚英文, 渲染使用的是n个blade, 终端的PS3只需要视频解码。

楼主你以后发帖可以跟战的时候一样认真么？

听不懂啊，解释一下嘛

？blade’s Cell 和 PS3's Cell的分别总看得出来吧？Blade就是刀片服务器, OK?

我也被你惊了，你是搞美工的？

谁说一定是Blade？

而且PS3－CELL做的也不只是视频解码  ........

抠字眼我没有兴趣。
