An immersive Augmented Reality Car Showcase platform that enables users to browse, customize, and visualize vehicles in their real-world environment using mobile Augmented Reality.

Built with React Native, Spring Boot, Blender, and Oracle Cloud Infrastructure to deliver real-time 3D customization and AR experiences.

AR Car Showcase (ARCS) combines mobile AR technology, cloud-based 3D processing, intelligent recommendations, and scalable cloud infrastructure to create an interactive vehicle exploration experience.

Users can:

• Browse a comprehensive vehicle catalog
• Customize vehicle colors and materials
• Generate personalized 3D models
• Experience vehicles through Augmented Reality
• Receive AI-powered vehicle recommendations
• Save and manage customized designs

When a user customizes a vehicle:

1. Customization request is submitted from the mobile application.
2. Spring Boot validates and processes the request.
3. Blender Service receives generation instructions.
4. Base vehicle model is downloaded from OCI Object Storage.
5. Materials and colors are applied dynamically.
6. A customized GLB model is generated.
7. Generated model is uploaded back to OCI Object Storage.
8. Model URL is returned to the application.
9. User can instantly view the customized vehicle in AR.

AR Car Showcase is deployed entirely on Oracle Cloud Infrastructure.

Deployment stack:

• Cloudflare
• Nginx
• Spring Boot
• PostgreSQL
• Redis
• Recommendation Service
• Blender Service
• Oracle Object Storage

The platform uses private VM-to-VM communication through Oracle VCN networking while exposing only the public API endpoint.

Blender Service

The Blender Service uses Oracle Cloud Instance Principals for secure access to Object Storage.

Benefits:

• No API keys stored in containers
• No OCI credentials mounted into Docker
• IAM-managed permissions
• Secure upload/download operations

This follows a production-grade cloud security approach for service authentication.
