In this tutorial, you’ll learn how to create a procedural animation using Geometry Nodes in Blender, guided by Johnny Matthews from the Blender Secrets channel. This video focuses on building a distance-based constraint within a simulation zone to achieve a dynamic animation.

Key Steps:

• Setup and Initial Movement:

• Create a line of vertices to represent the spine.

• Add Geometry Nodes to the mesh.

• Ensure vertices are ordered correctly for animation.

• Vector Math and Constraints:

• Convert the mesh to a curve for ordered points.

• Use an empty object to control the first point’s movement.

• Implement a distance-based constraint using vector math.

• Building the Animation:

• Set up a simulation zone.

• Use vector math to maintain constant distances between points.

• Iterate through points to apply the constraint.

• Adding Details:

• Add a body to the animation using a curve to mesh node.

• Include fins that follow the curve’s movement.

• Adjust the body shape with a vertex group for varied radius.

By following these steps, you’ll gain insights into procedural animation techniques and vector math applications in Blender.
