3D Viewer — 3D & CAD Viewer / Augmented Reality

3D Viewer is a professional Android application built with Kotlin and Jetpack Compose that combines a high-performance 3D rendering engine, native CAD/3D file conversion, non-destructive PBR material editing, media capture tools, and Augmented Reality (AR) visualization.

Key Features
1. Multi-Format 3D & CAD Support
Supported and Convertible Formats: .glb, .obj, and .stl.

2. Deep Android Integration: Open 3D models directly from WhatsApp, File Managers, web browsers, or via the system Share sheet (ACTION_SEND).

3. PBR Rendering & Material Editing
Adjustable PBR Properties: Real-time control over Base Color, Metallic, Roughness, Normal/Bump maps, and Ambient Occlusion (AO).

Texture Management: Instantly revert to the model's original textures at any time.

4. Advanced Graphics Settings & Environments
Visual Optimizations: Anti-Aliasing (edge smoothing), Dynamic Resolution (auto-adjusts to maintain target FPS), Dithering (reduces color banding), and Frame Rate Limiter (30 / 60 FPS).

-Background Environments: Night Black, Studio Gray, Dark Gray, and Clean White presets.

5. Transformation Controls & 3D Gizmo
Precise Manipulation (3D Gizmos):

Translation: X, Y, Z axis movement with custom sensitivity and metric steps.

Rotation: Pitch, Yaw, and Roll control with customizable angular increments (e.g., 45°).

Scaling: Uniform (1.0x) or independent per-axis (X, Y, Z) scaling.

Auto Center & Scale (ModelNodeExtensions): Instantly snaps models to the center of the scene using accurate 3D Bounding Box calculations.

6. HD Media Capture & Local MP4 Video Recording
GPU-Powered HD Screenshots (ScreenshotUtils): Direct GPU frame-capture exported as JPG or PNG without UI freeze.

Local MP4 Video Recorder (30 / 60 FPS): Internal video recording pipeline operating entirely without invasive system screen-capture dialogs or permissions (MediaProjection). 100% private, zero data usage, and rock-solid stability.

Alternative Screen Recording Service: Fallback recording option for full system workflows.

7. Augmented Reality (AR) Mode
Google ARCore Integration (ArViewerScreen): Project, anchor, and interact with 3D models at true 1:1 real-world scale on physical surfaces using the device camera.

8. Monetization & Virtual Economy
Coin Balance System: Built-in credit management for importing and processing high-fidelity 3D assets.

In-App Store (CoinsShopScreen.kt): Google Play Billing integration supporting one-time unlocks for the PRO Unlimited tier (lifetime ad-free access with unlimited conversions/imports).

AdMob Rewarded Ads (RewardedAdManager): Option to earn free credits by watching 30-second rewarded video ads.

9. Internationalization & Customization (i18n)
Multilingual Support (LocaleHelper): Seamless, in-app language switching across English, Spanish, French, Portuguese, and German.

Scoped Storage (SAF): Full user control over export destinations for renders, captured images, and recorded videos.

Ergonomic HUD Customization: Toggle on-screen camera and gizmo controls between left-handed and right-handed layouts.
