In about 1994, I wrote software for Windows 3.1 that let me add icons over an image in the app window and then create timed sounds and effects using these icons to represent the locations of the outputs. I built a crude timeline editor that triggered items only…
Continue readingI’ve been posting videos on YouTube () showing some working features and some failing features of the Linkage app for the Mac. Here is one of the latest: Even though this looks like a simple mechanism with a sliding quick-return that makes a link oscillate, thus moving a…
Continue readingWith the mechanism in the image, there are three sliding connectors affecting link 1 (on the left). This is an interesting mechanism to simulate. In this situations, the calculations are easy because D and E both have the same slide radius. With the same slide radius, we can…

Continue readingI managed to write a lowpoly shader for the built-in Unity terrain. The shadows were troublesome because I’m not using the URP (Universal render Pipeline) and I was writing the code and using macros that work with that renderer. Here’s the shader code: This is what I just…
Continue readingThe Windows Linkage app has a feature where you can control the position of inputs manually. I added this a long time ago and I just implemented the first thing that came to mind. What I did was add sliding controls, sort of like scroll bars, to pick…
Continue readingI am currently porting the Linkage app from Windows to the Mac. It’s a fun project with many challenges and many annoyances. Designing a Mac-style sidebar to show the properties of selected items was fun. Trying to use a Mac-centric help system is terribly tricky. For many years,…
