Enclosing class:

MedialAxis
```
public class MedialAxis.MedialDisk
extends java.lang.Object
```
Voronoi Disk. medial disk? maximal disk? Also inscribed disks.
A voronoi disk represents each node in the medial axis and has a corresponding triangle in the underlying Delaunay triangulation. A disk is the shape's maximal-inscribed circle located at the disk's center point -- a disk's radius is the distance to the nearest point on the shape edge from the disk center point.

- Field Detail
  - t
```
public SimpleTriangle t
```
    The underlying delaunay triangle associated with this disk
  - parent
```
public MedialAxis.MedialDisk parent
```
    This disk's parent node. Null if root node
  - children
```
public java.util.List<MedialAxis.MedialDisk> children
```
    This disk's children nodes. Nodes have upto 3 children. Leaf nodes have 0 children.
  - depthBF
```
public final int depthBF
```
  - depthDF
```
public int depthDF
```
  - degree
```
public int degree
```
    The number of children / outdegree
  - featureArea
```
public double featureArea
```
    The sum of triangle areas of this disk and all its descendants
  - distance
```
public double distance
```
    euclidean shortest path distance from root node circumcircle
  - axialGradient
```
public final double axialGradient
```
    Measures the change in the width of the shape per unit length of the axis (edge segment). When positive, this part of the object widens as we progress along the axis branch; if it?s negative the part narrows. The gradient for a given disk is measured using its parent node (i.e. how the gradient changes as we move towards this disk), rather than child (how gradient changes as we move away from this disk).
  - position
```
public final Coordinate position
```
    Centerpoint of this disk
  - radius
```
public final double radius
```
    The radius of the circumcircle of the disk's underlying triangle. Also equivalent to the distance between the disk center and the closest point on the shape
