interface nape.geom.IsoFunction
Available on all platforms
For 'flash' targets only.
*
* Iso-functions for MarchingSquares must be given
* as an object implementing this IsoFunction interface. This is for
* reasons of avoiding excessive memory allocations that occur through
* automatic boxing of arguments/return values when using function values.
*
* Since iso-functions may be called 10,000's of times per-invocation of
* marching-squares, this can quickly accumulate into a lot of GC activity.
