This package contains a framework and tools for working with curves and splines.
Splines are defined as implementing the ISpline interface. There are two default implementations, a mutable Spline class, and an immutable NativeSpline.
Splines are represented in the scene using the SplineContainer MonoBehaviour. Multiple splines can be stored in a single container.
Use SplineUtility to extract information from ISpline objects (ex, get a position at some interpolation).
Use Splines.cginc to import curve data data types and HLSL functions for working with Splines.
The default method of creating a Spline is the draw spline tool, which is accessed through the menu GameObject/Spline/Draw Splines Tool. This instantiates a new SplineContainer in the active scene, and enters the tool.
With the Draw Splines tool active, add points to the spline by clicking in the Scene View. Press the Enter/Return to end the point placement on the current spline and add points to a new spline of the same container. Press the Escape key to finish placing points.
To edit a Spline, open the Spline Tool Context by selecting a SplineContainer and toggling the Tool Context (in the Scene View Tools Toolbar) to Spline. Then, use the Move, Rotate, Scale tools to modify spline knots and tangents.
Splines can be extended through inheritance, or with SplineData<T>. The SplineData class is a key value pair collection type where key corresponds to an interpolation value relative to a spline. See the API documentation for more information on working with SplineData.
Import the Spline Examples scripts and scenes from the Package Manager Samples page.
