I have already created road parts in Dev Vlog 2. These are based on a single Cubic Bezier Curve. But since I also want to include intersections, I have to come up with a technique for this. Extruding along a curve is relatively easy. It becomes more difficult when the curve splits. How should the mesh know which vertices form the triangles? Based on these thoughts, I first wanted to better understand the Beziers and link them together to find possible techniques.

Im Dev Vlog 2 habe ich bereits Straßenteile erzeugt. Diese basieren auf einem einzigen Cubic Bezier Curve. Da ich aber auch Kreuzungen einbauen möchte, muss ich mir dafür eine Technik einfallen lassen. Das Extrudieren entlang einer Kurve ist relativ einfach. Schwieriger wird es, wenn dei Kurve sich aufteilt. Wie soll das Mesh wissen, welche Vertices die Triangles bilden? Auf Basis dieser Gedanken wollte ich erstmal die Beziers besser verstehen und miteinander verknüpfen um mögliche Techniken zu finden.
