See slideshow/source/engine/OGLTrans/unx/OGLTrans_TransitionImpl.cxx - have a look at all those makeOutsideCubeFaceToLeft(), makeFallLeaving() methods - it's really just a few (albeit cleverly thought-out) lines of code you need.

Deteted "Easyhack" from summary
adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility. see e.g. http://nabble.documentfoundation.org/minutes-of-ESC-call-td4076214.html for details
Are very grateful to have more transition effects to LibreOffice. As a user I wonder if these will be compatible (per style or category) with those used in Keynote or MS PowerPoint, so in this case besides mantenet the content and format, the display will be similar to the built in software different from LibreOffice. Here is the link for some videos showing the transitions found in Keynote or MS PowerPoint. http://m.youtube.com/watch?v=1fLQg5hFQQg http://m.youtube.com/watch?v=vSCydTaOdC8
I also think it would be great to add Powerpoint 2010 and 2013 3D transition effects and even Keynote equivalents.. Not really because of the cool 3D effects, but because of portability. I can't really ask a presenter. Could you please make or adjust your Presentation in Libreoffice Presenter so it will work exactly as you want in the next conference?. You see, we don't have Powerpoint. I think that if they bring their PPT presentations and see Libreoffice Presenter shows their presentations exactly the same as in PowerPoint, they would be encouraged to use Presenter insted of powerpoint or even Keynote. In the company that I work, our IT Department tested OpenOffice 3 and where thinking of moving everyone to OpenOffice, they installed Open Office to 1000 PCS.. The problem was that documents didn't open or show correctly... I know that LibreOffice developers have done a GREAT Job in making Libreoffice more compatible with MSOffice Docs, but 3D Transtitions are also great to have.

Andrzej: A polite ping are you still working on this ?
Note that in the meantime, we *did* get new 3D slideshow transitions: Vortex, Honeycomb, Glitter and Ripple. Nobody bothered or remembered to update this bug, though. Anyway, one thing the experience in imlementing those shows is that it definitely is not an Easy Hack. And C++ skill is not enough, as they are implemented mostly in GLSL, and that is what we want for further ones, too. We should probably drop the Easy Hack keywords?

Removing easyHack status as per comment#8, and since the code pointers are no longer valid. Please feel free to update the code pointers properly, and re-add the easyHack keywords. :)
