Discover how to create accurately spinning wheels in Blender using Geometry Nodes with Johnny Matthews. This tutorial walks you through setting up a wheel model, calculating its circumference, and using simulation nodes to ensure the wheel spins accurately based on its movement. You’ll learn how to convert global to local space and utilize the transform matrix sockets effectively.

Main Steps:

• Connecting the Wheel Model:

• Import and connect the wheel model using the Object Info node.

• Finding the Wheel Circumference:

• Use the Bounding Box node to calculate the wheel’s dimensions.

• Determine the circumference using basic geometry principles.

• Setting Up the Simulation:

• Implement the simulation nodes to track the wheel’s movement.

• Use the Self Object node to access the host object’s information.

• Global & Local Space – The Transform Matrix:

• Understand the difference between global and local space.

• Convert global movements to local space using transform matrices.

• Getting the Local Transform of the Wheel:

• Calculate the local transform to determine the wheel’s movement direction.

• Cleanup – Materials:

• Assign materials to the wheel for better visualization.

• Using the Menu Switch Node for More Options:

• Add flexibility by allowing the selection of different axes for diameter, direction, and rotation.

• Moving Up an Incline:

• Adjust the wheel’s orientation to ensure accurate tracking on inclined planes.

Johnny provides clear, step-by-step instructions, making it easy to follow along and implement these techniques in your own projects. For more exclusive content, visit Johnny’s Patreon. You can also find free assets on his Gumroad.
