-In the Spline Debug scene, there are 6 important objects:
-
-1. Spline
-- A curved spline going from (0, 0, 0) to (10, 0, -5)
-
-2. Deform
-- A curved spline used to deform Spline
-
-3. Spline Plus
-- An object with the SplinePlus component
-- This object is used to deform spline Spline along spline Deform
-- The resulting spline is rendered in green with Gizmos enabled
-
-4. Evaluate
-- Renders a cube gizmo along each of the above splines at a given distance from a given anchor point
-
-5. Nearest Point
-- Renders a cube gizmo at the nearest point along the deformed spline from the Spline Plus object
-
-6. Spline Debug
-- An instantiated Blender file including a tube warped around the deformed spline using Blender's Curve modifier
