Technical Specification: Free Online 3D Model Viewer
Overview
This application is a high-performance, client-side 3D model viewing tool. It allows users to drag and drop common 3D formats (.gltf, .glb, .obj) into the browser to render them in a clean, professional, and interactive workspace.
Core Features
- Drag-and-Drop Interface: Intuitive file loading zone.
- Universal Format Support: Support for GLTF/GLB and OBJ/MTL formats using Three.js.
- Interactive Camera: Smooth orbit controls for zooming, panning, and rotating (Left-click rotate, right-click pan, scroll zoom).
- Display Controls:
- Wireframe toggle mode.
- Background color picker (focus on neutral grays and whites).
- Lighting intensity slider.
- Scene Information: Display of model statistics (vertex count, face count) to help verify model quality.
- Privacy-First Design: Zero backend processing. All rendering happens via local GPU acceleration.
UI/UX Design
- Aesthetic: Clean, professional "SaaS" aesthetic. Light background (#F8FAFC), crisp shadows, and a blue primary action color (#2563EB) for buttons.
- Layout:
- Header: Clean title and brief helper text.
- Viewport: The main area is a full-bleed
<canvas>element container. - Control Sidebar: A floating sidebar on the right (desktop) or bottom (mobile) containing all toggles and inputs.
- Animations: Subtle fade-in animations for the UI panels upon file load. Smooth camera interpolation when centering the model.
Technical Implementation Directives
- Architecture: Everything must reside in a single HTML file using CDN links for Three.js (r150+).
- State Management: Use in-memory variables only. Do NOT use localStorage or any browser storage mechanisms.
- Compatibility:
- Ensure the application is safe for sandboxed iframes (avoid accessing parent frame).
- Replace any browser alerts with custom floating DOM notification elements.
- Performance: Implement lazy loading for the Three.js library assets if possible, though CDN links are required.
- Responsive Handling: Use CSS Grid/Flexbox to adjust the canvas aspect ratio based on device orientation (landscape vs. portrait).
