* This class provides a default implementation of a controller for the MarchingCubesSurfaceExtractor. It controls the behaviour of the

* MarchingCubesSurfaceExtractor and provides the required properties from the underlying voxel type.

*
|
||||
* PolyVox does not enforce any requirements regarding what data must be present in a voxel, and instead allows any primitive or user-defined
|
||||
* type to be used. However, the Marching Cubes algorithm does have some requirents about the underlying data in that conceptually it operates
|

* on a <i>density field</i>. In addition, the PolyVox implementation of the Marching Cubes algorithm also understands the idea of each voxel
|
||||
* having a material which is copied into the vertex data.
|
||||
*
|

* Because we want the MarchingCubesSurfaceExtractor to work on <i>any</i> voxel type, we use a <i>Marching Cubes controller</i> (passed as
|
||||
* a parameter of the MarchingCubesSurfaceExtractor) to expose the required properties. This parameter defaults to the DefaultMarchingCubesController.
|
||||
* The main implementation of this class is designed to work with primitives data types, and the class is also specialised for the Material,

* Density and MaterialdensityPair classes.

|

*
|
||||
* For primitive types, the DefaultMarchingCubesController considers the value of the voxel to represent it's density and just returns a constant

* for the material. So you can, for example, run the MarchingCubesSurfaceExtractor on a volume of floats or ints.
