I actually went through all my blog entries and removed spam. That means that you won't be able to find anymore links to stuff that can enlarge your penis. I hope this action will not shatter your lives and you'll find consolation in all the spam that you're getting via email anyway. And if not I saved some of the links. You never know, I say.
I also changed the template, I'd slap something ninja related on it, but I don't have anything that fits. Besides nowadays everyone is a graphics ninja. I'm counting hours until the term will be added to the dictionary. So my new nickname will be "The Lost Son of Norway, Duke of Poland and King of England". Aim high is my motto.

As a proud owner of exactly zero babies I got lots of time to think about stuff. Mostly about squirrels, goats and the letter q. So I wanted to talk about some of the things I've been thinking about lately.

Our friend ("our" as in the KDE communities, if you're not a part of it, then obviously not your friend, in fact he told me he doesn't like you at all) Ignacio Castaño has a very nice blog entry about 10 things one might do with tessellation.
The graphics pipeline continues evolving and while reading Ignacio's entry I realized that we haven't been that good about communicating the evolution of Gallium3D.
So here we go.

I've been slowly working towards support for geometry shaders in Gallium3D. Interface wise the changes are quite trivial, but a little bigger issue is that some (quite modern) hardware, while perfectly capable of emitting geometry in the pipeline is not quite capable of actually supporting all of the features of geometry shader extension. The question of how to handle that is an interesting one, because just simple emission of geometry via a shader is a very desirable feature (for example path rendering in OpenVG would profit from that).

I've been doing some small API cleanups lately. Jose made some great changes to the concept of surfaces, which became pure views on textures. As a follow up, over the last few days we have disassociated buffers from them, to make it really explicit. It gives drivers the opportunity to optimize a few things and with some changes Michel is working on avoid some redundant copies.

A lot of work went into winsys. Winsys, which is a little misnomer, was a part of Gallium that did too much. It was supposed to be a resource manager, handle command submission and handle integration with windowing systems and OS'es. We've been slowly chopping parts of it away. Making it a lot smaller and over the weekend managed to hide it completely from the state tracker side.

Keith extracted the Xlib and DRI code from winsys and put it into separate state trackers. Meaning that just like WGL state tracker, the code is actually sharable between all the drivers. That is great news.

Brian has been fixing and implementing so many bugs/features that people should start writing folk songs about him. Just the fact that we now support GL_ARB_framebuffer_object deserves at least a poem (not a big one, but certainly none of that white, non-rhyming stuff, we're talking full fledged rhymes and everything... You can tell that I know a lot about poetry can't you)

One thing that never got a lot of attention is that Thomas (who did get one of them baby thingies lately) released his window systems buffer manager code.

Another thing that didn't get a lot of attention is Alan's xf86-video-modesetting driver. It's a dummy X11 driver that uses DRM for modesetting and Gallium3D for graphics acceleration. Because of that it's hardware independent, meaning that all hardware that has a DRM driver and Gallium3D driver automatically works and is accelerated under X11. Very neat stuff.

Alright, I feel like I'm cutting into your youtube/facebook time and like all "Lost Sons of Norway, Dukes of Poland and Kings of England" I know my place, so that's it.
