This is a quick video to show the simulator controls working in the Linkage Mac application that I'm working on. The start, stop, pause, etc., menu items and buttons all work as planned. The code even calls into the simulator code and then updates the window. The frame rate is 60 FPS, give or take a few frames, except when I drag the entire view. This isn't using the fanciest streaming timers to ensure exact framerates, but it's probably as accurate as needed. I plan to drop the frame rate to 30 FPS just because it's unnecessary to see the animation any smoother than that. I'll still be able to do 60 steps per second in the simulator to get better accuracy than in the Windows app. The only time the simulation needs this better accuracy is when there is some oscillating motion so fast that the simulator moves a link past a limit instead of having it reach the limit and head back in the opposite direction. Other than the issue with that sort of glitch, the accuracy is still as accurate as IEEE 64-bit floating point math.
