Did any one know about Renderscript in android 3.0
Also I want to know the difference between OpenGL and RenderScript
If you know provide me some good example or demo link
There isn't a great deal of information. I assume better documentation is forthcoming at some point. But for the moment I think this is the bulk of it:
http://developer.android.com/guide/topics/graphics/renderscript.html
I think the docs explain how OpenGL and Renderscript work together.
And definitely check out the samples.
