A couple of readers have asked about the diagrams in this series of Special Relativity posts. I created them with the freeware 3D ray tracing application, POV-Ray. The diagrams are actually three-dimensional “scenes” designed to be viewed as flat pieces. If some of the “dots” look more like little spheres, that’s because they are!
I wrote some introductory posts a while ago (here, here, and here). You can read those if you want more details about the application.
For a little (optional!) Friday fun, I thought I’d share some POV-Ray images that have a bit more “dimension” to them.
As reported earlier, this week got off to a rough start. I let my guard down (foolishly) and got nabbed by the greedy PC rapists. All I wanted was to find a particular font for a project. The next day a more careful search turned up exactly what I needed, the fonts and just the fonts (ma’am).
Monday I mentioned that I planned to share my font-needing project with you. It’s not finished (many of my projects live a long time as I tweak them — some are living things that grow and improve forever). But it turned out so much better than I expected, I just had to share it with you this Science Fiction Saturday.
I’m also going to boldly try a new WordPress blogging trick!
Back on my first Sideband post, I wrote that, “Sideband posts are miscellaneous thoughts that accompany the main thread of posts. Think of them as small paths that meander off the main road. Some branch off, go a short ways and die after a short while. Others are scenic trails that follow along the main road.”
They never quite achieved that vision, so this year one goal is getting Sidebands back on track with that original “mission statement.”
And I’m going to start with fun topic: computer-generated 3D images!
