VLRadius4P
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Analytical Geometry
Introduced first in SolidGeometry 1.0, Creation date: 2012-12-10, Last change: 2025-09-14
returns a contour based on 4 points similar to VLBezier4P
Will be removed (2025-09-21): Use 'VLradialEdges' instead
Description
Generates from 3 segments, defined by 4 points a curved 2nd segment, that uses a radial curve to transfer the first segment as tangent into the 2nd segment and the tangent of the 2nd segment is the 3rd segment. The procedure can be used to defined curves between an even number of points. (4:6:8:&). The second delivered vertex list has more supporting point on long straight lines.
