Tokamak4: high quality pulse

February 25, 2010 at 4:40 pm 5 comments

In monday after getting bored of being a long time without programming (I told in my previous post that I was in vacation, even hitting the personal record of 2 weeks without programming!), I was talking with Nuno Pinheiro a.k.a ‘da design guy’ of KDE. When he asked me if there was a way to make the KDE 4.4. SC pulse effect with really bigger scaled factor, I was thrilled.

After considering some different approaches and thinking about the limitations, it got to be fast, got to look pixel perfect to please the UI designer and *can’t* break the so loved or hated BC (Binary Compatibility), I got this results: at left there is the new pulse optimization and at right the normal pulse (you can also download the file in ogg format).

The code has still a bug that the pulsed shadow is not centered in the new code but it is looking promising specially for high DPI screens. Another remark is that the animation was set to have a long duration to make it easier to notice the pixels in the outer limits of pulsed shadow.

      Heh! Actually it was a strategy to see if people can say which one is smoother. 😉

    does it mean, this effect will be part of kde sc 4.4.1?

      The pulse is already part of SC 4.4. The ‘improved’ one has to be tested and *will not* work in every case.
