When I did the SVG images for illustrating the website, I created a tiny drawing program to facilitate drawing Bézier curves. Why not just use an existing drawing program? Because I’m not too fond of the drawing programs I’ve tried: they’re too complicated and too influenced by the WYSIWYG (“what you see is what you get”) idea of user interaction, which means that they hide the actual code from you, making things difficult to automate and integrate with other software. My ideal is WYSIATI, “what you see is all there is”, which for instance can mean writing SVG code in a text editor. And that was how I started before realizing that defining curve segments was tedious to do by hand and, so I wrote some interactive code to do that.
It all runs in a web browser and can be used without installing anything, starting from the Bezd web page. Instead of writing a manual, I thought it was easier to make a little video that demonstrates it, so here’s that:
