Renovix

Renovix is an AR-first iOS application focused on real‑world spatial visualization of furniture and interior elements. The project explores how modern iOS AR stacks can be composed into a production‑grade interaction pipeline, balancing real‑time rendering, spatial accuracy, and extensible architecture.

Rather than positioning itself as a polished consumer product, Renovix is intentionally built as a systems-oriented AR application — prioritizing correctness, performance, and long‑term scalability over surface‑level features.

What Renovix Is About

Renovix allows users to:

• Browse interior and furniture products through a lightweight SwiftUI interface
• Preview 3D assets using system‑level Quick Look
• Place and inspect objects in real‑world environments using AR
• Evaluate scale, lighting, and spatial fit before decision‑making

The core emphasis is on how AR systems are structured, not just how they look.

Technical Focus

Renovix is designed to mirror real production ARKit workflows, with attention to the same constraints faced by shipping AR applications:

• End‑to‑end AR interaction pipeline

  • AR session setup with coaching overlay
  • Horizontal/vertical plane detection with visualization
  • Raycasting‑based object placement with floor snapping
  • Ghost preview with real-time gesture manipulation

• Interactive AR Controls

  • Tap to place ghost preview
  • Pan to slide object on detected surfaces
  • Pinch to scale objects
  • Rotate to adjust orientation
  • Two-finger vertical pan to adjust height

• Persistence & Data

  • CoreData-backed storage for placed items
  • Repository pattern with dependency injection
  • Position, rotation, and scale persistence across sessions

• Rendering performance

  • Centralized ModelLoader service with caching
  • SceneKit-based AR rendering with ARSCNView
  • Efficient ghost node management during placement

• Testability

  • Unit tests for ViewModels (ARViewModelTests, ProductViewModelTests)
  • Mock repositories for isolated testing
  • Swift Testing framework integration

Architecture Overview

Renovix follows a layered architecture intended to scale beyond a prototype:

• UI Layer

  • SwiftUI‑driven views
  • Declarative state management
  • UIKit bridges where system frameworks require delegation

• AR & Rendering Layer

  • ARKit for spatial tracking and environment understanding
  • SceneKit (ARSCNView) for 3D rendering and object placement
  • ModelLoader service for centralized USDZ asset loading

• Interaction Layer

  • Raycasting‑based placement
  • Modular gesture handling
  • Scene‑safe update logic

• Data & Domain Layer

  • CoreData for persistence (PlacedItem)
  • Repository pattern (ARItemRepository, ProductRepository)
  • AppContainer for dependency injection
  • Mock-friendly data sources for testability

This structure ensures that UI changes, data sources, and AR behavior can evolve independently.

Implementation Progress

Renovix has evolved through incremental, intentional phases, each reinforcing architectural stability rather than feature count.

Current development emphasizes:

• Architectural stabilization
• Clean separation of responsibilities
• UI restructuring aligned with AR‑first interaction models
• Robust handling of real‑world AR constraints

The project is actively structured to support:

• Future networking integration
• Persistent scene storage
• Expanded interaction models
• Advanced AR features without rework

---

Assets & Models

This repository intentionally excludes heavy 3D assets (.usdz, .reality) due to size and licensing considerations.

The AR pipeline is designed to:

• Load models dynamically
• Fail gracefully when assets are unavailable
• Use placeholder geometry to preserve behavior and demonstrate system flow

This keeps the repository lightweight while preserving architectural integrity.

Why Renovix

Renovix is not a UI experiment or a one‑off demo.

It is a technical exploration of AR system design on iOS, demonstrating:

• Practical use of ARKit and RealityKit in non‑trivial flows
• Performance‑aware rendering strategies
• Modular, extensible code organization
• Real‑world engineering tradeoffs faced in production AR apps

The project is intentionally positioned to reflect how AR features are engineered, not merely showcased.
