Hi
I'm working on a drawing app and using openGL to draw the bitmaps on
all touch points. So far I'm successful in drawing bitmaps on all
touch points I get (including touch points in historical data) and the

There is bug reported in the android bug base:
http://code.google.com/p/android/issues/detail?id=1740
Could it be because of the same reason?
Is there a better way of doing it? Is it possible to improve
performance using a canvas?

Hello All,
Can anyone point to good tutorials which describe how I can smoothly
scroll a background on a glSurfaceView?
I need to have a horizontally scrolling background with various
objects that auto-scrolls as your character/player moves just like
various car/motorbikes games.

Hi,
I need to apply mesh warping on an image in android. Method
drawBitmapMesh can be used to define a mesh and apply the bulge warp
effect on an image.
This is the algorithm that can be used:
Remap pixels according to:
For each x, y

y' -> rn*Sin[a] + .5
where
a = ArcTan[x
