- com.metsci.glimpse.core.support.selection.QuadTreeFloatBuffer

```
public class QuadTreeFloatBuffer
extends Object
```
A QuadTree backed by a FloatBuffer containing x/y coordinates of points stored in tree. Points are references by the QuadTree using their index into the FloatBuffer. Points are assumed to be packed into the FloatBuffer like: [ x0, y0, x1, y1, ... ]
