Bézier curves make lots of curve operations/calculations easier, so they’re very important. (Like a toolkit with a Swiss army knife where one of the layers is a Go-Gadget.) You can see using my PathParser from last time that the two shapes below have the same absolute points and appear identical: const sameShape = PathParser.parse( sameShape ) ->, ,, , ] PathParser.parse( sameShape ) ->, ,, , ]Ĭ / c commands are called bézier (bezYAY) curves, created/formalized by and named for two French engineers, de Casteljau and Bézier, pioneers of computer-aided design (CAD). Remember in my last post on SVG paths I explained the tag can replace every other shape tag? As it turns out, within descriptors, the C and c commands can replace every other command except the initial M / m. Today we’ll be covering one particular very important command: the C / c cubic bézier curve command.
I explained last time that paths have commands with parameters, expressed in either absolute (viewbox coordinates) or relative (distance from previous coordinate) terms. To recap: we’re focusing again on s (sequences of lines and curves), which form 90% of most vector graphics. And SVGs are light, fast and a natural fit for manipulation and animation. A talented vector artist can please nearly any taste: minimalism to realism and nearly everything in between. Today I’m following up on a previous blog post about one of my favorite subjects: vector graphics - just about the easiest way to make your web app stand out in a crowd. Their work has been incredibly helpful in my personal projects! This blog post wouldn’t have been possible without it! The code is now a bit out of date so I’ve taken the liberty of updating/adapting it. Humble thanks to Particle in Cell, a California-based tech consultancy, and this fantastic article on their blog.
