The position, orientation, and scale of a 3D object within a virtual environment, represented as a combined transform: translation (X, Y, Z world coordinates), rotation (quaternion or Euler angles), and scale factors. Accurate pose determination underpins AR object anchoring, motion capture replay, physics simulation, and hand-object interaction in XR systems.

Overview
- Virtual object pose defines how 3D objects are positioned and oriented within virtual environments. Precise pose tracking enables realistic object manipulation, physics simulation, and AR/VR interactions. Pose estimation algorithms detect real-world object positions for digital overlay applications.
