- com.badlogic.gdx.graphics.g3d.particles.ParticleSorter

Direct Known Subclasses:

ParticleSorter.Distance, ParticleSorter.None
```
public abstract class ParticleSorter
extends java.lang.Object

- Method Detail
  - sort
```
public abstract <T extends ParticleControllerRenderData> int[] sort(Array<T> renderData)
```
    Returns:
    
    an array of offsets where each particle should be put in the resulting mesh (also if more than one mesh will be generated, this is an absolute offset considering a BIG output array).
  - setCamera
```
public void setCamera(Camera camera)
```
  - ensureCapacity
```
public void ensureCapacity(int capacity)
```
    This method is called when the batch has increased the underlying particle buffer. In this way the sorter can increase the data structures used to sort the particles (i.e increase backing array size)
