Old but popular video that I removed from YouTube now made available here on PeerTube.
In a previous OpenSCAD video I demonstrated the line and polyline module. As promised I will expand on this by creating Bezier curves with it. A Bézier curve is a parametric curve that is often used in computer graphics. Bézier curves are used to model smooth curves that can be scaled indefinitely. The name comes from the French engineer Pierre Bézier who used them to design automobile bodies in the 1960’s.
Examples of programs with Bézier curve functionality are Inkscape and Solvespace, a 3D CAD program. In a recent video I used the Bézier curve in Solvespace to create a 3D printable Vase. OpenSCAD doesn’t have built-in Bézier functionality but due to the nature of OpenSCAD we can add it.
Earlier I uploaded a video that demonstrated line and polyline modules as a replacement for the built-in polygon in OpenSCAD. Today we expand the use polyline together with the Bézier function to create a Vase.
