It’s like digital archaeology– understanding the ancient (by internet time) workings of less advanced engineering efforts. Pop culture depictions of archaeology would have us believe that those who toil in the field are searching for that one artifact that would neatly solve the entire puzzle at hand. Historically, perhaps the artifact that came closest to fitting this archetype was the Rosetta Stone, and even that was incomplete (if I’m observing the pictures correctly).
So it is with my current investigation. Much like Sean Connery playing Indiana Jones’ dad searching for the Holy Grail in The Last Crusade, I run the risk of making the Duck TrueMotion 1 algorithm my lifelong obsession. I got that Duck TM1 source code into a state where I could compile it against a standalone program. It only required 38 C source files from the original vpvision source tree and a mess of attendant header files to boot.
