Common APIs to segment types.

Associated Types

Required Methods

Start of the curve.

End of the curve.

Sample the curve at t (expecting t between 0 and 1).

Sample the derivative at t (expecting t between 0 and 1).

Split this curve into two sub-curves.

Return the curve before the split point.

Return the curve after the split point.

Return the curve inside a given range of t.

This is equivalent splitting at the range's end points.

Swap the direction of the segment.

Compute the length of the segment using a flattened approximation.

Provided Methods

Sample x at t (expecting t between 0 and 1).

Sample y at t (expecting t between 0 and 1).

Sample x derivative at t (expecting t between 0 and 1).

Sample y derivative at t (expecting t between 0 and 1).
