I got my new code singing certificate and I fixed a few minor bugs. Super short dimension lines were becoming infinite due to the space calculated for the arrow heads. There was also a problem with gear and link rotation angles that went wrong after about two rotations…
Continue readingI have a plan. It’s not a very good plan, but it is a plan. The mechanism above presents a problem that I have written about a few times in the past. The EGJ triangle is what I call a “link triangle.” It is a set of links…
Continue readingFYI, I was able to easily install Windows 10 running in a virtual machine on my MacBook Pro. I got a trial copy of Parallels and it handled the Windows 10 installation seamlessly. I already had a Windows 10 product key so it was free (so far). And…
Continue readingSomehow, I missed that my code signing certificate was about to expire. And Symantec needs me to do the whole notarized identification thing to renew it. This means that I can’t produce a new Linkage program with a bug fix that I wanted to distribute, at least not…
Continue readingThis is the last Beta version of Linkage 3.3. Get this Beta version here: http://www.rectorsquid.com/temp/linkage.msi The video seems to be working properly and so does the image export. It’s almost time to release the new Direct2D version of the Linkage program. And wow do those smooth lines look…
Continue readingI am mostly done with the smooth drawing version of the Linkage program. I am using it on a high-DPI screen so more testing is needed to make sure everything works right for everyone else. But since it is close, I have a Beta version available for anyone…
Continue readingI have a lot of the GDI functions converted to Direct2D functions. I am still using the GDI pens and brushes, so I just create Direct2D equivalent objects at the time the Direct2D functions are called to draw stuff. Old GDI Drawing New Direct2D Drawing I have arcs,…
Continue readingI wanted to let everyone know to try GeoGebra. It is a software package that is a math program that can be used to design mechanisms. The Linkage software is great for many people trying to throw together a quick prototype mechanism but for some people, it may…
Continue readingI decided to spend a few minutes tonight implementing a Direct2D renderer for the Linkage program. After a few failed attempts a year ago, I finally got it right and am able to draw lines. Just lines. Nothing more – no circles or text or anything else. And…
Continue readingI had a user send me a mechanism that they thought should work. It turns out that none of the connectors were forming connections between links. I plan on making a tutorial about common problems like this and I’m writing this post in order to help those who…
