ANDROID Perlin Noise clouds & CPU-Usage & Bitmaps

Hi there,

I know there are probably millions of topics out there about this, but I can’t seem to find a good tutorial on how to do it. The problem is that the FPS drops… Are there any CPU-friendly ways to do it? Or shall I just have a noise tileset. I’ve already implemented a Perlin Noise gen. If there is any article about it, let me know.

As you probably know it needs an alpha level, yet I don’t know how to accomplish it, because the bitmap is like only changing the alpha-level of all the pixels… The clouds only have 1 color and 3 alpha levels(AL). the first AL is like 0% transperant, the second AL is like 33% Transperant etc…

So basically, how to make clouds and changing alpha levels of them. Only use words if you can, I need to write my own program and learn from it ^w^!
