Vector path trajectory imitation

A system comprising:

• a processing device;
• and
• a computer-readable storage medium storing instructions that, responsive to execution by the processing device, causes the processing device to perform operations including:
• identifying a path as a freeform line in a user interface having a first anchor point and a second anchor point;
• selecting reference points along one or more vector paths of a reference curve offset from the path based on the first and second anchor points;
• calculating a resultant curve offset from the reference curve based on the path, the first and second anchor points, and the selected reference points of the reference curve;
• and
• outputting the resultant curve in the user interface as offset from the reference curve.

One or more computer-readable storage media storing instructions that, responsive to execution by a processing device, causes the processing device to perform operations comprising:

• selecting a reference curve having a first reference point and a second reference point from one or more vector paths displayed in a user interface;
• identifying a path having a first anchor point and a second anchor point as input via the user interface at a location offset from the reference curve;
• calculating a resultant curve based on the location of the path in the user interface and a trajectory of the reference curve in the user interface based at least in part on:
• determining a length of the reference curve between the first reference point and the second reference point;
• determining a first distance between the first anchor point and the first reference point,
• determining a second distance between the second anchor point and the second reference point;
• and
• executing a vector path trajectory imitation algorithm based on the length of the reference curve, the first distance, and the second distance;
• and
• outputting the resultant curve in the user interface with the resultant curve as offset from the reference curve based on the location.
