Open Any Model.
Inspect Every Angle.
A private, high-performance 3D GLB viewer for Android. Inspect 3D models with real-time HDR lighting, smooth 60 FPS touch gestures, and instant folder scanning.
Built for Precision 3D Inspection
Experience fluid GLB rendering powered by Google Filament with responsive touch controls and folder management.
Real-Time Filament Engine
Physical-based rendering (PBR) computes realistic reflections, surface roughness, and metallic highlights at a locked 60 FPS.
Natural Orbital Touch
Rotate with a single finger, pan with two-finger drags, and pinch or use HUD sliders to zoom into fine mesh details.
Dynamic Scene Lighting
Tune environmental illumination on the fly and switch between adaptive theme, pure black OLED, and white studio backdrops.
SAF Folder Discovery
Choose folders via Android Storage Access Framework. Filion scans them recursively and lists all GLB models with persistent grants.
Direct Android Open With
Tap any `.glb` model in your browser, file manager, or chat app to immediately open and view it inside Filion.
100% Offline by Design
Filion declares zero network permissions. Your proprietary 3D models and device metadata never leave your local storage.
Intuitive Controls Over Scene & Camera
