SplinePoint

Remarks

Two tangents rather than one, so a corner is expressible. A single tangent forces the curve to be smooth everywhere, and the thing a road and a camera track both need is the occasional hard corner — which is TangentIn ≠ −TangentOut. Mirroring them is what SmoothTangents does, and it is a choice the author makes per point.

Offsets, not directions. Their length is the curve's speed leaving the point, which is what a Hermite segment is parameterised by. Normalising them here would make every segment take the same shape regardless of how far apart its ends are.

Fields and properties (4)

• public Vector3 Position

  Where it is.

• public Vector3 TangentIn

  The tangent the curve arrives on, as an offset from .

• public Vector3 TangentOut

  The tangent the curve leaves on, as an offset from .

• public float Roll

  How far the frame is twisted about the tangent at this point, in radians.

Methods (3)

• public SplinePoint(Vector3 Position, Vector3 TangentIn, Vector3 TangentOut, float Roll = 0)

  One control point of a Spline.

• public static SplinePoint At(Vector3 position)

  A point with no tangents, which makes the segments through it straight.

• public static SplinePoint Smooth(Vector3 position, Vector3 tangent, float roll = 0)

  A point whose two tangents mirror one another, so the curve is smooth through it.
