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
x' -> rn*Cos[a] + .5
y' -> rn*Sin[a] + .5
where
a = ArcTan[x - .5, y - .5]
rn = r^2.5/.5
r = Sqrt[(x - .5)^2 + (y - .5)^2]
Here is API Demo example how we can use it.
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/BitmapMesh.html
But somehow when I use it, I do not get the desired output.
Can anyone please help?
