ObjectTransform

class · immutable data

public class ObjectTransform

Namespace: AR51.Unity.SDK

A plain, immutable data class describing a single object's pose. Construct one and hand it to ObjectTransformConsumer.OnObject; the consumer creates (if new) or updates a prefab GameObject keyed by Id, selecting the prefab by Type. All properties are get-only — there is no way to mutate a pose after construction.

Units

Position is in Unity world-space meters. Scale is a local scale (unitless multiplier). Use a Quaternion for Rotation, not Euler degrees.

Properties

All get-only.

Property	Type	Description
Id	string	object identifier — the key the consumer tracks GameObjects by
Type	string	object type — selects which prefab the consumer instantiates
Position	Vector3	world-space position, in meters
Rotation	Quaternion	world-space rotation
Scale	Vector3	local scale

Constructors

public ObjectTransform(string id, string type, Vector3 position);
public ObjectTransform(string id, string type, Vector3 position, Quaternion rotation);
public ObjectTransform(string id, string type, Vector3 position, Quaternion rotation, Vector3 scale);

Three overloads, from minimal to full pose. Omitted arguments take Unity defaults:

Constructor	Rotation	Scale
(id, type, position)	Quaternion.identity	Vector3.one
(id, type, position, rotation)	supplied	Vector3.one
(id, type, position, rotation, scale)	supplied	supplied

Exampleinferred

// Place an object 2 m forward, 1 m up — meters, Unity world space.
var pose = new ObjectTransform(
    id: "crate-7",
    type: "crate",
    position: new Vector3(0f, 1f, 2f));

ObjectTransformConsumer.Instance.OnObject(pose);
