fractionOfProjectionToVector Method
Return fractional length of the projection of the instance onto the target vector.
- To find the projection vector, scale the target vector by the return value.

fractionOfProjectionToVector(target: Vector3d, defaultFraction: number0): number
@returns the signed length of the projection divided by the length of target
| Parameter | Type | Description |
|---|---|---|
| target | Vector3d | the target vector |
| defaultFraction | number | the returned value in case the magnitude of target is too small |
Returns - number
the signed length of the projection divided by the length of target
