IBM将在GDC上对PS3 CELL进行技术演示！（CELL独自演算300W多边形的城市）

http://gametomorrow.com/blog/ind ... -power-at-gdc-2007/

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.




本周在游戏开发者论坛上IBM将展示一个LINUX基于PS3实时绘制一个复杂的城市景观(3000000多边形)， 使用1080P协议，只使用软件描绘报文交换集中技术

PS3 在LINUX下，RSX不用，用CELL软RENDERING

1080p，300万TRIANGLE



CELL的潜力渐渐明朗！！

不用显卡?好厉害

看图片没有什么光源特效，很一般
GPU还是不可缺少的

Achievement Unlocked~

看完了。

这是分到其他blade处理的，不是一台PS3单独处理。
就是IBM宣传cell的分散处理--cell的最大卖点。

祝PS3早日降价
降到RMB千元以内
