Bezier Cam Designer Experiment The experiment is working. The JavaScript code allows a fixed number of points to be manipulated to create a poly-Bezier shape. The Bezier curve is drawn “by hand” for both the normal version and for the version that uses polar coordinates. The interesting thing…
Continue readingI am playing around with some code related to Bezier curves. Although many programming languages provide a Bezier curve drawing function, I need my own. I need it so that I can translate a string of Bezier curves into polar coordinates for drawing a cam. See my older…
Continue readingI have started work on adding cams to the Linkage program. It has taken me a while to add this feature because of the complex nature of cams. For instance, cams can be used to control valves in an engine or they can be used to control the…
Continue readingI made a minor change to add keyboard commands to the Linkage program. It already supported the typical Control-C, Control-S, etc., keyboard shortcuts for operations like Copy and Save. It now support single key operations like C or J for Connect and Join, as well as a few…
Continue readingI have been experimenting with overlaying a div on top of the iframe used for the YouTube video player. So far, I have come up with a method of showing a high quality preview instead of the crappy thumbnail preview image that YouTube generates for my videos. There…
Continue readingI made another improvements to the Linkage video code. It now gives 1080p HD video in the High Quality mode. It also generates the HD video using the full video area regardless of the size of the window on screen. Better Quality Video If the video doesn’t look…
Continue readingI made this alternative to the traditional watt linkage for a beam engine. This changes the location of the pivot that controls the parallel motion. You can look at a few older posts to find the original design. Alternative Watt Linkage
Continue readingI have a Windows program written in C++ using MFC. MFC handles some things very well but there are some oddities in it that are a bit painful to handle. Using the document/view architecture is a good idea if the document can be separated from the actual view…
Continue readingI changed the Linkage program so that a click anywhere within a link will select it. This is in addition to the already existing code that would detect a click anywhere within about 8 pixels of the edge of a link. That selection distance was also increased for…
Continue readingHigher Quality Video Higher Quality Rendering The video creation feature now supports the standard quality and a higher quality setting. The standard quality is not very fast because of the time that is spent rendering the video frame. The higher quality rendering uses some anti-alias techniques to get…
