So, I didn't find an easy way to use openGL rending with Plasma::Wallpaper.
For example, if I want to make some openGL desktop animation like screensaver, or interactiv animation like phyiscs desktop.

here some example :

So , I have no idea how to do that.. Need Kwin ?It will be very nice , if we can use a QGLRender as wallpaper.

I tried doing opengl rendering with my starfield wallpaper but it didn't work out so well. Firstly I had to make an invisble QGLWidget then do my GL drawing there. Then I called QGLWidget::renderPixmap or QGLWidget::grabFrameBuffer, I can't remember. After that I got less than 20 FPS which is slower than normal rendering. And also it draws over everything if you actually set it as your wallpaper.

I hope someone can make it easy to use openGL for plasma wallpapers. Perhaps someone who is interested in a GSOC project

You may wish to ask on the Plasma development list as there may be other methods in which to accomplish it, which would not paint over everything.

I posted a request to the plasma mailing list.

You can already use plasmo??ds over your screensaver.
I don't think anything is needed actually but a plugin for Plasma::Wallpaper so you can use a screensaver as a wallpaper.

A long-date proposal, but we're still waiting for a concretisation.

Is there some news about it?

The only hope seems to be QML2 - as long as it is another solution, but unfortunately it requires a lot of resources.
