6.20.1 A Sphere Tube

This is perhaps the simplest possible example of using the CREATION method: a sphere which follows a path leaving copies of itself behind.

1. Create a CREATION method.

2. Create a sphere under it.

3. Add the following tag to the sphere:

                   SCRE l=1

4. Create a PATH method to the same level with the sphere (under the CREATION method) and a B-Spline curve under the PATH method.

Play the animation and the PATH method moves the "sample" object along the path while the CREATION method creates one new sphere in each animation frame. The target objects created by the method have all the properties of the sample object.
