 # BezierSpline
+
+[Smooth Bézier Spline Through Prescribed Points](https://www.particleincell.com/2012/bezier-splines/) for Android Platform.
+
+Helps to simulate curves such as `Sine Curve`, `Wave` etc...
+
+![Wave](docs/wave.gif)
+
+
+## Usage
+
+Copy [BezierSpline.java](bezier-spline/src/main/java/com/xujiaao/android/bezier/spline/BezierSpline.java) to your project.
+
+````java
+private final Path mPath = new Path();
+private final Paint mPaint = new Paint();
+private final BezierSpline mBezierSpline = new BezierSpline(20);
+...
+
+@Override
+protected void onDraw(Canvas canvas) {
+    final float width = getWidth();
+    final float density = getResources().getDisplayMetrics().density;
+    for (int knot = 0, knots = mBezierSpline.knots(); knot < knots; knot++) {
+        final float x = knot * (width / (knots - 1F));
+        final float y = (float) (Math.toDegrees(Math.sin(Math.toRadians(x / density))) * density);
+        mBezierSpline.set(knot, x, y);
+    }
+
+    mBezierSpline.applyToPath(mPath);
+    canvas.drawPath(mPath, mPaint);
+}
