Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`delete()`
`static long`	`getCPtr(ConvexHull2D obj)`
`double`	`getMinDist(Vector2D vertex)`	if the vertex is inside the convex hull the minimum distance to any of the half-spaces of the hull is returned.
`boolean`	`isInside(Vector2D vertex)`	test if the given vertex is inside the convex hull
`void`	`rebuild(SWIGTYPE_p_std__vectorT_rw__math__Vector2DT_double_t_t vertices)`	rebuilts the hull
`SWIGTYPE_p_std__vectorT_rw__math__Vector2DT_double_t_t`	`toContour()`	create a plain trimesh from the hull facets

    rebuilts the hull
    
    Parameters:
    
    vertices -
  - isInside
```
public boolean isInside(Vector2D vertex)
```
    test if the given vertex is inside the convex hull
  - getMinDist
```
public double getMinDist(Vector2D vertex)
```
    if the vertex is inside the convex hull the minimum distance
    to any of the half-spaces of the hull is returned. If its not inside
    0 is returned.
    
    Parameters:
    
    vertex -
    
    Returns:
    
    minimum distance to vertex

public SWIGTYPE_p_std__vectorT_rw__math__Vector2DT_double_t_t toContour()
```
    create a plain trimesh from the hull facets
    
    Returns:
    
    the hull facets as a plain triangle mesh with normal information
