DPlex support, including parallel rendering video

27. October 2008

The Equalizer source tree now contains support for DPlex decompositions. This was the last scalable rendering feature missing, which means that the client library is now 1.0-ready. Yeah!

But fear not, we’ve got plenty in store for the following Equalizer releases leading to the 1.0. And even after version 1.0 we have plenty of features and optimizations in store to push the boundaries of scalable rendering performance.

I’ll now test and fix some corner cases of DPlex, like multi-level decompositions, before the 0.6 release. For normal DPlex mode, the feature is already working well, see for yourself:

Equalizer in Action

15. October 2008

In the near future there are two events where you can get a live Equalizer demonstration.

The first one is IEEE Vis next week in Columbus, OHIO. Max from the University of Zurich will give demonstrations in the Interactive Demonstrations Lab.

The second one is Siggraph Asia in December, where Renato Pajarola is contributing to the Interactive Massive Model Rendering course.

Feel free to pass by and talk to us!

OpenGL Window System APIs – Ease of Use

14. October 2008


I’ve just gathered a quick statistic on the lines of code for the Equalizer sample implementations for GLX, WGL and AGL. All implementations do approximately the same thing.

There is very little difference between the window systems. Surprisingly, GLX ‘wins’ even though it is the oldest API of the three.
