Voxelization
During my work on my thesis, I have needed a way to detect edges in a point cloud. The classic way to find edges is with a Hough transform. In a point cloud, that quite work. The next point is an arbitrary distance away that we can’t know a priori. To solve both of these, we need to regularize the spacing. This is called “voxelization,” a portmanteau of “volume” and “pixel.” For this case, I was working with a three dimensional cloud onto a two dimensional space first, which luckily makes this process a bit simpler.
Trying out RCS Version Control
For managing my thesis documents, git was not quite the right solution. I didn't need the fancy distributed development features, since (sadly) nobody was interesting in contributing paragraph commits. What I did need was the easiest way to save revisions of my writing and view old versions
