Marching Squares
What's a good way to deal with inner contours when using marching squares?
Right now for my first point, I scan through the nrrd data until I hit a value that falls below the cutoff point. Once I hit this value I call my marching squares function at that point. Afterwords, I scan again until I hit a value above cutoff value. Once this value is hit, marching squares is called on this edge and I continue scanning until I hit another value below then cutoff value, repeating the process over and over again until I reach the end of the data. This seems to yield pretty good results, but is extremely slow and inefficient.

Results can be seen here. (Isovalue is 50% of maximum.)
