So I'm taking a computer graphics course in openGL right now, and for the first lab we are to among other things implement three line drawing routines. First off a normal DDA algorithm, that's easy..

New Year postcard. Implements custom 2D rendering algorithms including Bresenham's line drawing, Bézier curves, and flood-fill from scratch. Built with Java Swing for Computer Graphics class.

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 someone be ...
