====== Glossary ======

=== Spline ===
GameObject with the CurvySpline component attached
=== Control Point ===
A point controlling a spline's curvation (sometimes called "Node" by others). Control Points are regular GameObjects with the CurvySplineSegment component attached, always child objects of a spline and automatically managed.
=== CG ===
Abbreviation for [[.generator:]]
=== CP ===
See [[#Control Point]]
=== Tangent ===
The Tangent vector is the (normalized) direction of a spline point
=== Up ===
The Orientation- or Up-Vector defines the Upside of a spline point. Together with the Tangent it forms the rotation used by controllers for a given spline point
=== Total Fragment ===
Also known as TF. A relative position on the spline, ranging from 0 (start) to 1 (end)

The TF of a control point is shown in it's inspector.

This is the "time" parameter used in the splines' formulas. A point's TF is not proportional to its distance from the spline's start. Depending on the spline, a value of 0.5 does not always mean the middle, distance wise, of the spline.
=== TF ===
See [[#Total Fragment]]
=== F ===
A relative position on a spline segment, ranging from 0 (start of segment) to 1 (end of segment)

The F of a control point is shown in it's inspector.

F is not proportional to its distance from the segment's start. Depending on the spline, a value of 0.5 does not always mean the middle, distance wise, of the segment.
=== Distance ===
A distance on the spline, ranging from 0 (start) to spline's length (end)

The Distance of a control point is shown in it's inspector.
=== Relative Distance ===
A normalized distance on the spline, ranging from 0 (start) to 1 (end)

It is defined as: Distance / Spline_length

The Relative Distance of a control point is shown in it's inspector.
=== Orientation Anchor ===
Used by dynamic Orientation mode, this [[#Control Point]] option tells Curvy Splines to use the transform rotation of the [[#Control Point]] as an orientation target. Think of "orientation" waypoints.
