UxtManipulationMoveLogic

Implements a move logic that will move an object based on the initial position of the grab point relative to the pointer and relative to the object, and subsequent changes to the pointer and the object's rotation

Usage: When a manipulation starts, call Setup. Call Update for querying a new position for the object.

function Setup

void Setup(
    const FTransform & PointerCentroidPose,
    const FVector & GrabCentroid,
    const FTransform & ObjectTransform,
    const FVector & HeadPosition
)

Setup move logic by caching initial input values

function Update

FVector Update(
    const FTransform & PointerCentroidPose,
    const FQuat & ObjectRotation,
    const FVector & ObjectScale,
    bool UsePointerRotation,
    const FVector & HeadPosition
) const

Provide updated input and head/camera position to retrieve new object position
