Hey everyone,

I'm currently in Salt Lake City for the annual Brianshare conference.
Nat Friedman and Guy Lunardi will be demoing compiz during their Monday
(today) and Friday keynotes. I've been helping out with getting the
demos set up and they'll be showing a bunch of new cool compiz features,
especially on Friday.

Here's the link to the page where the live/recorded keynote webcasts
will be located:

If you wanna see David presenting the latest stuff @Brainshare, watch the friday session over at http://www.novell.com/brainshare/general_sessions07.html and slide to minute 25 :)

Is it just me, or is there no sound?

[rememo]

Hmm, strange using Ubuntu 7.10 (feisty fawn) I've got sound playing. Maybe you'll need a newer flash-plugin? Feisty ships with 9.0.31.02 flashplugin-nonfree and it works for me.

[imnotpc]

Yeah, I've got proxy/firewall issues. :(

Edit: Use the test link to troubleshoot connection problems. It works fine now.

I hope they provide a version with AVI or Ogg.

[karmapolice]

Wow, he is doing an awesome job.

[ioannis]

very exciting stuff indeed

are input transformations now upstream (xorg)? Should we expect inclusion in Xorg 7.3?

[ioannis]

to answer my own question, it seems 'input transformations' are indeed planned for Xorg 7.3 release:

from http://wiki.x.org/wiki/XDC2007Notes

The planned features for 7.3 katamari (1.4+ xserver, ~May 2007)

* XACE merged (almost done)
* Apple's OSX support (pended for 7.2 release to not disturb it)
* lobotomized generic DGA (will be done, straightforward)
* input hotplug (ready)
* GPU -> CRTC mapping property for randr.
* input transformation
* active module deprecation
* PCI rework


so that's good news!

Really, really impressive...
- input transformations of course, with the ability to zoom a cloned region and continue working on either zoomed or not region,
- zoom on "resized" windows, I had never seen that before,
- window on top of the cube, I want it ! :)
- different wallpapers and xwinwrap, pretty funny ;)

Cool presentation

(and cool jeans too, I did not imagine David like that at all ;))

I thought I might comment on one of the things I noticed:

The way David scales all windows and then zooms in on them one by one/ chooses just the ones he wants to work on seems a pretty different model for using/organising windows to the one we have now...right?
It looks really cool - you can see all things laid out in front of you - MUCH more like when you put books on a desk - we can really only work on/look at/read from one thing at a time, so this kind of model would seem to be 'better' for a desktop

I think it would be cool for Compiz to supprt this kind of usage more easily - like creating a mode where MOST windows are scaled at any time and you can select ones to be large (+shift click to select many)

It makes me hungry for miniwin! SURELY now it is time ;P

How far is this kind of thing from 'true resolution independence', is that even similar?

[ioannis]

ah! "resolution independence" the Holy Grail of DEs :)

I thought 'input transformations', as the name implies, allow windows to have any shape and still be able to interact with them, where 'active' regions (regions you can interact with your mouse for instance) are transformed accordingly to match the visual representation of the window/object/widget. Or other manipulations of the 'inputs' that allow redirection (i.e. cloned regions), etc.

In David's presentation we see I high resolution image that he zooms in and is not pixelised (i.e. 'resolution independent'). I think this is some kind of interaction between the application and Compiz, in a similar way it's done now for video (newly added interface). I think this is not covered by 'input transformations'.

I guess, in whatever way this is done, one peace that's still missing for a nicely drawn 'resolution independent' DE, is an svg decorator. I noticed on the presentation, the window borders were pixelised when zoomed in.

does anyone have more concrete info on these matters?

[delphinen]

Awesome presentation, I cant wait for the next release of Xorg!

I personally think this was actually a demo of input transformation. Imagine you have a big window with the full-resolution image and resize it, but only visually, I mean, drawing its contents smaller. Of course, you have the original texture at its full size at your disposal, why scaling it down? This effect is possible even now, or it was half a year ago when I last tried :), but the window does not interact correctly then, that is where the input trf-s come into play.
