Class InterpolationDto

Points through which the BSpline will be created

Indicates wether BSpline will be periodic (closed, tangent-continuous at the seam)

tolerance

Parametrization controlling point spacing along the curve. When omitted, chord-length is used (backward-compatible). Centripetal is recommended for uneven spacing as it resists cusps and overshoot.

Optional tangent direction enforced at the start (non-periodic only).

Optional tangent direction enforced at the end (non-periodic only).

Optional per-point tangent directions (one per point); entries that are undefined are left free. When provided, takes precedence over startTangent/endTangent.
