[Insight-users] Bresenham Line Iterator

[Benjamin King]

Hello,

I needed to trace bresenham lines in an image and combined a 
PolyLineParametricPath and a PathIterator to do this. Worked, but was a 
little slow, so I took the PathIterator code and implemented a LineIterator 
based on it that only iterates ND bresenham lines. A test program is about 
4000 times faster on my machine, but your mileage may vary.
Feel free to use the code/integrate it in ITK or whatever.

Cheers,
	Benjamin
