Accelarated OpenGL-based transition effects for KPresenter

I don't think only Krita may get some OpenGL love. So I started to hack together a couple of transition effects for KPresenter, based on OpenGL:


Later on when I'm finished I'll prepare a patch set for KOffice 1.5, of course if there is demand for it. Otherwise, just wait for 1.6 or 2.0 then.

See you tomorrow in LinuxTag !

Just because opengl _can_ do 3d, doesn't mean it has to. A simple smooth fade can look nicer than any windows flying around everywhere.

But still, very nice.

Very nice :-)

It would be also very nice if kpresenter had modern shadow effects (similar to KeyNote) as well as great placement helper (similar to KeyNote again).

Thanks for this great work. I hope one day KDE would have a vectorial support (copy/pasting, apps interoperability) as good as OS X.

That's pretty nice.

Imagine you in a presentation and show stuff using these effects and no one knowning how you did in a simple and quick way :)

Nice oportunity to show KDE to the world.

Nice work!

As some other anonymous person said, transitions do not have to be 3d to look nice - in fact they are often quite distracting (although I would adore water ripples or perhaps even a big wave that washes away the old slide :-) ). I would love to see smooth overlay fading or blurring transitions. Also page zooming would be very very nice - imagine having a highres picture (of say, an insect) that you zoom in a lot (from full body to a single complex eye) using a smooth OpenGL zoom function. Have a look at the OpenGL pdf presentation tool KeyJNote over at http://keyjnote.sourceforge.net/ which has some of this stuff implemented in python.

Keep the good code coming! :-)

Do you know fiesta Gold? I like it.
My brother often go to the internet bar to buy fiesta money and play it.
After school, He likes playing games using these fiesta online gold with his friend.
I do not like to play it. Because I think that it not only costs much money but also spend much time. One day, he give me many buy fiesta Gold and play the game with me.
I came to the bar following him and found fiesta online money was so cheap. After that, I also go to play game with him.

Since long it was known that WebGL is coming to Firefox, but we never knew it would come as a surprise out of the wild. sportsbookFirefox’s latest nightly builds now include an implementation of WebGL. Here is some background: WebGL is an emerging standard that promises to bring Hardware accelerated 3D graphics to the browser. Mozilla’s WebGL project gives web developers a way to connect the HTML 5 Canvas tool, which can be used to display complex graphics in the browser without plug-ins like Flash, to the OS’s native, hardware accelerated graphics engine, OpenGL.
