Worked on the gtiosclub/ARchitect repository to deliver a 3D text annotation feature for augmented reality experiences. Using Swift, ARKit, and RealityKit, replaced the previous SwiftUI Text info box with a 3D text entity generated via MeshResource.generateText, attaching it directly to the top of AR cubes. This approach improved rendering fidelity and ensured that text annotations maintained stable, cube-relative positioning during AR interactions. The implementation focused on seamless integration within the AR session, emphasizing code quality and user experience stability. No major bugs were reported, and the work was validated through multiple commits to ensure consistent and reliable behavior.
