JSegmenten
JSegmenten is a family of geometric primitives used in computer-aided design and geographic information systems to represent smooth curve sections between waypoints. The term is used primarily in Dutch- and German-speaking CAD contexts. Each JSegment connects two fixed points while enforcing a controlled bend described by a joint parameter J, which governs the initial curvature and overall bending behavior.
An instance is defined by endpoints P0 and P1, a unit tangent direction at P0, and a
Mathematical properties include a parameterization on the interval [0,1], a finite length, and the ability to
Applications and usage span road and rail design, highway alignment, and general CAD modeling where smooth
