Wheel Rotation

This node computes the rotation of a wheel if travelling along a distance. The distance is based on the movement of an item.

Controls

Wheel Radius

Use this control to enter the radius of the wheel to rotate. This value can currently not be enveloped because that would require evaluating the whole envelope up to the current frame every time the node is evaluated.

Movement Reference

The reference item to use to compute a travelled distance. This may be the wheel itself if “Use World Distance” is used.

Use World Distance

Use the world coordinates of the Movement Reference item to compute the travelled distance. If disabled, the local movement of the item is used.

Use X/Y/Z Distance

Toggle which axis positions are used to compute the travelled distance.

Samples per Frame

If the movement has intricate turns, increasing the number of samples will increase the accuracy of the computed distance - but will also slow down evaluating it.

First Frame / Override

Last Frame / Override

These two settings determine the first and last frame of the scene used to calculate the travelled distance. The Override toggles need to be activated to change the first and last frame respectively.

Rotation Channel

This determines the rotation channel the wheel rotation will be copied to if the Rotation Vector output is used.

Node Connections

Rotation

The rotation of a wheel travelling the path of the Movement Reference item up to the current frame.

Distance

The distance travelled by the Movement Reference item up to the current frame.

Rotation (Input) / Rotation Vector (output)

The Rotation input is passed through to the Rotation output. Any computed wheel rotation will replace the rotation channel selected by the Rotation Channel Control
