The ToWorld method of the Transform struct is used to convert a local transform into a world transform. This method takes a Transform object representing the local transform of a child and returns a new Transform object that represents the equivalent world transform.
Use the ToWorld method when you need to convert a local transform to its corresponding world transform. This is particularly useful when dealing with hierarchical transformations where a child object's transform is defined relative to its parent, and you need to determine its absolute position, rotation, and scale in the world space.
// Example usage of Transform.ToWorld
Transform parentTransform = new Transform
{
Position = new Vector3(10, 0, 0),
Rotation = Rotation.FromAxis(Vector3.Up, 45),
Scale = new Vector3(1, 1, 1)
};
Transform childLocalTransform = new Transform
{
Position = new Vector3(2, 0, 0),
Rotation = Rotation.FromAxis(Vector3.Up, 30),
Scale = new Vector3(1, 1, 1)
};
Transform childWorldTransform = parentTransform.ToWorld(childLocalTransform);
// childWorldTransform now contains the world position, rotation, and scale of the child object.
