LowPoly

LowPoly on Android. Convert a picture into LowPoly style. It has two steps to finish this process. First use Sobel operator to get the edge on image, then use Delaunay Triangulation to generate triangles from these edge points and some random points. Finally fill color on these triangles, we will get the LowPoly style picture.

Download

dependencies {
    compile 'me.fichardu.lowpoly:lowpoly:1.0.1'
}

Usage

Two ways:

LowPoly.getLowPolyBitmap(Bitmap bitmap, int accuracy, int randomPointCount);

This will Convert a bitmap into LowPoly style bitmap directly.
LowPoly.lowPoly(int[] pixels, int width, int height, int accuracy, int pointCount);

This will generate Delaunay Triangles from the given bitmap`s pixels. Then you can use these triangles to draw on canvas.
