This node computes the rotation of a wheel if travelling along a distance. The distance is based on the movement of an item.
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.
The reference item to use to compute a travelled distance. This may be the wheel itself if “Use World Distance” is used.
The direction (in local coordinates) on the Movement Reference that will be designated as forward in the direction of travel.
Use the world coordinates of the Movement Reference item to compute the travelled distance. If disabled, the local movement of the item is used.
Toggle which axis positions are used to compute the travelled distance.
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.
These envelope is evaluated as the travelled distance for the wheel is computed. A value of less than 100% will slow down the wheel rotation (0% is a complete standstill), a value higher than 100% speed up the rotation. This can be used to lock wheels or overcrank them.
This determines the rotation channel the wheel rotation will be copied to if the Rotation Vector output is used.
If a Rotation vector is connected to the input, this control defines how the Rotation Channel will modify the respective rotation channel on the input vector. This allows for the daisy chaining of multiple wheel nodes.
The rotation of a wheel travelling the path of the Movement Reference item up to the current frame.
The total distance travelled by the Movement Reference item up to the current frame.
The distance travelled by the Movement Reference item up to the current frame taking the Rotation Multiplier into account.
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
