 Posted: Tue Dec 11, 2007 6:41 pm Post subject: First triangle rendered by Gallium3D Cell/PS3 driver |
 |
|
Brian and the guys of tungsten graphics have release the first screenshot of Gallium3D for Cell. There is a lot of work to do.
Brian:

The Gallium/Cell driver is drawing its first triangle.
This is by no means "real" code but it exercises sending a drawing
command to the SPUs, get/putting framebuffer tiles and displaying the
results.
In the attachment, the background and triangle colors are tweaked a bit
per-SPU so you can see which SPU drew which tile.

Hhm, my email is public. There are no mails with hiring offers :).
My point is very simple. It is easy to prototype spu based rasterizer. Two-days work, no more.
It is hard to write good spu code in large software project. Refactoring is myth on spu. Bad design means re-engineering.
Good luck for Tungsten guys. |

seems it is a resolution issue, im running on a standard def telly at the moment, and the only way this would run is setting
#define WIDTH 400
#define HEIGHT 300
but it just renders a corrupt display |

| It's an SDL app, so it will work on X or directfb or whatever you have SDL compiled to support. |

i just compiled SDL in the standard way, didnt realise there was any options for alternate configurations. im having the same problem with the ppc version of mesa3d as well, it says to run it without X compile it as linux-solo but i dont thik this is a ppc version, and it certainly doesnt want to build
whats this directfb, had a quick look at the site and couldnt work out what im supposed to do with it |
