getSegmentendD

getSegmentendD is a function used in computational geometry, computer-aided design, and path representations to obtain the end distance associated with a segment. In many contexts, end distance (D) refers to the value that marks the segment’s end within a parametric or cumulative system, such as the distance from a defined origin to the segment’s termination along the segment’s local axis. The exact interpretation of D can vary by library or application, but it generally serves as a scalar that identifies the segment’s endpoint along a specified reference.

Typical behavior and interpretation

getSegmentendD accepts a representation of a segment and returns a numeric value representing the end distance. If the call provides an origin or reference frame, the function measures from that origin to the segment’s end; otherwise, it is commonly equal to the segment’s length when the segment is defined by a start point, a direction, and a length. The function is usually read-only and pure, with no side effects.

Parameters and return

Common parameters include a segment object (defining start point, direction, and length), and optionally an origin point or coordinate frame and a set of options (such as units or measurement mode). The return value is a numeric distance D. If inputs are invalid, implementations may throw an error or return a sentinel value such as NaN, depending on the API.

Usage considerations

Because the exact meaning of end distance depends on the surrounding data structure, users should consult the specific library’s documentation for getSegmentendD to understand its parameter conventions, unit handling, and error behavior. It is often used alongside related functions such as getSegmentLength, getSegmentStartPoint, and getPointOnSegment in workflows involving path planning, stitching of segment sequences, and geometric querying.
