there are three lightening talk sessions scheduled for this week: one during the odf day, one today and one tomorrow. i chaired the one today and it was about kde in general. unfortunately they weren't taped (only the contrib conference was).
the presenters were:
Torsten Rahn on Marble, a 3D geography planner
Stephan Binner on Kerry, a KDE frontend to beagle
Thomas Zander on Flake, the new document component model in koffice2
Alfredo Beaumont on KFormula, the amazingly complete mathml component he wrote as part of a summer of code project
Kevin Krammer on QtCenter.org, a community forum for people writing software with qt
Nadeem Hassan on his kde4 SIP library
Junkyu Park on KLDraw, a 3D opengl lego designer
Jos van den Oever on Strigi, his really cool indexing engine (he also did a BoF on it earlier in the week)
i was particularly impressed with the mathml app which renders some 70-80% of mathml properly and supporters even more than that with various rendering glitches, whereas the open office mathml tool only does some 20-30% of the mathml standard.
Junkyu's (segfault on irc) app was similarly impressive. he claimed it to be "unfinished" and then loaded up a very complex lego model with hundreds of pieces in three dimensions, moved pieces around, built sub models interactively and then rendered it to a high quality via povray. he has plans for blender as well and already supports the full ldraw standard in all 2500 pieces glory. amazing. he promises to release it soon for all of us lego addicts to play with. it's also the only ldraw app for linux/unix.
looking forward to tomorrow's lightening session.
