First off a normal DDA algorithm, that's easy.. Then off to Bresenham and midpoint, but almost all sources I have found says that Bresenham and midpoint is the same one.

Hi, I am looking for something like Xiaolin Wu's line algorithm except with 3D input and 3D output. The output would not be projected onto a 2D surface; it would be a 3rd order tensor. Might ...

And no, this isn’t the more famous Bresenham’s line algorithm you may be more familiar with, it’s much simpler, but does work on the same principle of replacing expensive arithmetic division ...
