I’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 have a Mac App Store “page” for the Linkage app. “Linkage” was a taken name so I opted for “Linkage CAD”. let me know if that’s a bad name. You can’t see the app yet because it needs to be releasable before I can submit to Apple…
Continue readingI think I have an installable version of the 3D Lander game: https://www.rectorsquid.com/Lander/Lander.msi This is a Windows installer file that is digitally signed by me with my code signing certificate. If You encounter this Linage.msi file and installing it doesn’t show my name as the publisher, run away….
Continue readingYou can download a copy here: https://www.rectorsquid.com/Lander/Lander.zip It’s not code-signed so you might get warnings. I’ll work on code-signing it later. You would need to connected a game controller your computer to have it work well.
Continue readingToday, I worked on the Linkage for Mac app. I had been running into an issue where changing a setting to track the open sidebar panel triggered a callback in the editor, notifying it of the setting change. This caused a crash when the editor view called a…
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,…
Continue readingI work in Java and Swift very often. Swift lends itself to writing fewer lines of code, which appeals to me because maintaining fewer lines of code always seems easier. But more importantly, fewer lines of code to do the same thing is more elegant, in my humble…
