Waimea Developer Returns From Beyond 37

Posted by timothy from the prettiness dept.
An anonymous reader writes "Waimea 0.5.0 was released after about a year from the developer disappearing. It turns out he was just working on getting the OpenGL backend for Cairo completed. Waimea is the first window manager that uses Cairo for rendering."

    This is a good example of a submission that cries out for a little "Here's what the hell this article is talking about..." trailer. That's the place to add your two cents, not Michael-ish "Here's the acceptable position to take on this controversial subject." comments.

    "Waimea is the first window manager that uses Cairo for rendering."? To me, "Cairo" is Windows 95.

    • Indeed. WTF is Cairo other than Windows 95?

        Cairo: Cross-device Rendering for Vector Graphics [keithp.com]
        • Cairo provides a vector-based rendering API with output support for the X Window System and local image buffers. PostScript and PDF file output is planned. Cairo is designed to produce identical output on all output media while taking advantage of display hardware acceleration through the X Render Extension.


        • Cairo provides a stateful user-level API with support for the PDF 1.4 imaging model. Cairo provides operations including stroking and filling Bézier cubic splines, transforming and compositing translucent images, and antialiased text rendering. The PostScript drawing model has been adapted for use within C applications. Extensions needed to support much of the PDF 1.4 imaging operations have been included. This integration of the familiar PostScript operational model within the native application language environment provides a simple and powerful new tool for graphics application development.

            OpenGL is a stateful programming language, in that you can call glColor3f(1,0,0) and then everything will be painted red until you select another color.

            Although they're not a programming language, the command-line tools are a good example of statelessness...you call ls or dir and it performs its function, and then it's done.

          "New tool"? Credit where credit is due: Sun created the NeWS windowing system (Gosling's project prior to doing Java); and NeXT (Jobs' project before Pixar and rescuing Apple) used Adobe's Display PostScript. Note that none of these exist anymore, but maybe the time has come for this idea to really work. MacOS 10 has Quartz, and that seems to be working out, unlike those earlier attempts.

      Sorry to nitpick, but Cairo was what Win2000 became, without a lot of the advanced features that are giving the Longhorn developers fits. The Win95 codename was Chicago.

    You know all that Next generation Windows Avalon stuff?

    Cairo is linux's answer.

    It's vector graphics that now uses an OpenGL backend. As soon as glitz is complete (another component of the NG linux desktop) Keith Packard (that guy that got kicked out of XFree86 and then utterly destroyed XF86) will be doing a quick OpenGL based X server.

    At this point, The only driver that graphics card companies need to produce is an OpenGL one. That's really simple.

    And the desktop is 3d accelerated. Mmmm....

        Vector graphics is where is going to be, screen size won't matter with vector graphics, as icons with stay in proportion with your resolution(such as svg which is a part of Cairo).

        Once these technologies mature a bit, it will give Microsoft a run for their money. Xorg should have compositing by the summer(so I read), Xfixes and Xdamage are already part of it. Good bye David Dawes and your old XFree86.

        I've since lost the link, but I once saw a video demonstrating some of the capabilities of Avalon. It's a fully vector-based graphics rendering system. The video started with simple things like rotating buttons and text at angles.

      Cairo: Vector graphics rendering library that can take advantage of XRender and other such extensions, especially those supplied by:

      Keith's X Server: A redesign of X Servers, focussing on "Modern" design and features used by modern X Software. (Client side fonts, composing offscreen.)

      Wiemea: X Window manager that uses Ciaro for output and rendering.

      The theory is that Ciaro will become the standard way of drawing graphics, and since everything is vector based, it becomes resoultion independent. (Increasing the resolution doesn't make things smaller unless you want it to - it simply makes things smoother.)
    • window applications, much like web pages, use bitmap graphics for things which really should be vectors : simple, scalable, size-of-image independent from size-of-file graphics.

    So this is a submission about three screenshots showing a GNOME desktop - oops, I mean waimea. Seriously, even though 3 screenshots might be interesting, but can someone point out something waimeaish on those screenshots (aside from that 16x16 pager like thing on the right bottom corner)?

    A link would have been helpful to the source of the info. (Unless the developer whispered it in the submitter's ear).

      There's maybe something wrong with your compilation

      Actually its faster cos dragging windows around doesn't bump up the cpu load to 100%.
