Nikolaos Kousis developed a 3D text annotation feature for the gtiosclub/ARchitect repository, focusing on enhancing AR user experience and rendering fidelity. He replaced the previous SwiftUI Text info box with a 3D text entity generated using MeshResource.generateText, attaching it directly to the top of AR cubes. This approach ensured that text annotations maintained stable, cube-relative positioning during AR interactions, improving integration within the AR session. Working exclusively in Swift and leveraging ARKit, RealityKit, and SwiftUI, Nikolaos validated the implementation across multiple commits, emphasizing code quality and robust 3D rendering. No major bugs were reported during this development period.
