| Summary: | The article considers two graph-analytical algorithms.
The first algorithm makes it possible to form a spatial
curve passing through given nodal points with
direction vectors specified at these points. The second
algorithm allows you to generate a flat compound curve
passing through the given nodal points with direction
vectors and curvature radii specified at these points.
The constructed curves are formed by cubic Bezier
segments. Direction vectors are treated as a control for
the shape of the curve being constructed. At the nodal
points, second-order geometric smoothness is ensured,
due to the continuity of the slope and curvature. A
distinctive feature of the proposed algorithms is the
significant use of constructive means of computer
graphics. |
