Simple Bounce Curve is a Blender add-on from Polyfjord that generates a bounce curve connecting selected objects based on their origin. Working with at least two objects, it produces a single curve you can shape to taste, making it a compact addition to the Blender extensions library.
To use it, select two or more objects in the 3D viewport and run Object > Create Bounce Curve. The Curve Height can be set with the slider in the redo panel that appears in the lower-left corner, and in Edit Mode you can tweak the curve's control point handles directly.
Version 1.1.0 added Dynamic Curve Height, which scales the height based on the distance between selected objects, and changed the default height factor to 0.1 meters. It also improved handle types, giving sharp control points zero-length handles for more realistic curvature. The add-on requires no special permissions, is compatible with Blender 4.2 LTS and newer, and is released under the GNU General Public License v3.0 or later.
