AS3 Flash: Low CPU Clouds Animation – Perfect for Mobile
In our our recent tutorial on clouds effect via BitmapData.perlinNoise and ColorMatrixFilter, we presented a nice clouds animation but very CPU intensive and not suitable for larger images or for mobile devices. Here we present a version that is extremely CPU efficient, runs very well on Android 2.2, and can be used to generate large images. In the two examples linked below we generate 500 by 380 animations.
