Linkage Program

I had some C++ code that would determine if any element in a list was selected. A “selected” element is one that has a boolean variable “isSelected” set to be true: bool bLinkSelected = false; POSITION Position = pConnector->GetLinkList()->GetHeadPosition(); while( Position != 0 ) { CLink* pLink =…

A Linkage document file contains coordinates based on there being 96.0 pixels per inch. If the software is rendering onto an old monitor then the document units are scaled based on the amount of zoom in effect and then they are translated to different coordinates if the document…

I am porting the Linkage program to the Mac in Swift, as I’ve mentioned in other posts. I’m trying to be “Swifty” because a language should be taken advantage of and because I like to learn new programming paradigms (or simply styles since this might not be a…

In the image above, there is a complexity that cannot be handled by the Linkage simulator. Although it might not look complicated, the lack of kinematic chain simulation in the software makes this impossible to simulate. The Linkage software, as I have written about on numerous occasions, uses…

I’ve started porting the Linkage software to the Macintosh (“Mac” for those of you who have never heard it called by its “real” name). So far, the only problems I’ve had are those related to the design being done wrong; The language changes are insignificant since I program…

Since cam simulation involves finding the “best” place on a spline to place a sliding connector, there are bound to be small problems caused by the cam shape. I realized that this can actually cause terrible problems when a cam is using an open spline. The simulation difficulties…

I have been dumbfounded for years. I want to maybe write the Linkage program in Swift for the Mac. I absolutely need GPU acceleration to get good performance and that has eluded me for quite some time. I was unable to find any article, until now, that told…

I just made a new beta Linkage app available. And yes, I did just call it an “app” because “program” sounds too old-school. The beta is here: http://www.rectorsquid.com/beta/linkage.msi. The video above shows one of the newest simulation improvements. The little triangle link with two sliding connectors was not…

The data in the Linkage program is set up in what seemed like the best way possible when I first wrote it. There is an overall document object and in that object is a list of links, a list of connectors, and a list of splines. Within a…
