GLB Free Online 3D File Viewer and Inspector

To open a GLB file, drop it on this page. The GLB Viewer reads it in your browser and draws the mesh so you can orbit, zoom, and check the shape. Nothing is uploaded. A preview shows the geometry you can see. It does not slice a print, and it does not decide that the file is finished.

Professional GLB 3D File Viewer for TRELLIS.2 Outputs

Our free online GLB Viewer is the perfect companion for viewing 3D models created with TRELLIS.2 and other 3D generation tools. Whether you're a game developer, 3D artist, product designer, or 3D printing enthusiast, this browser-based viewer lets you inspect your 3D assets without installing any software. Experience professional-grade 3D visualization directly in your web browser with full support for PBR materials and real-time rendering.

Why Use Our Online 3D Viewer?

When working with TRELLIS.2's AI-generated 3D models, you need a reliable way to preview your creations before committing to your production pipeline. This page opens GLB, GLTF, OBJ, STL, FBX, PLY, VOX, and 3MF files in the browser. The intuitive orbit controls let you rotate, zoom, and pan around your model to examine every detail from any angle. Unlike desktop software that requires installation and system resources, our web-based solution works instantly on any device with a modern browser.

Perfect for TRELLIS.2 Workflow

TRELLIS.2 generates high-quality 3D models with PBR textures that export perfectly to GLB format. Our viewer renders these textures accurately using WebGL technology, showing you exactly how your model will appear in game engines like Unity and Unreal Engine. The real-time rendering ensures smooth performance even with complex meshes containing hundreds of thousands of polygons. Verify your TRELLIS.2 outputs instantly without waiting for heavy software to load.

Key Features

• Intuitive Controls - Orbit, pan, and zoom with mouse or touch gestures on any device
• Privacy First - All processing happens locally in your browser, files never leave your device
• Mobile Responsive - Full functionality on tablets and smartphones with touch controls
• Instant Loading - WebAssembly-powered parsing for fast model loading up to 50MB

Supported 3D Formats Explained

Our viewer handles the most widely-used 3D file formats in the industry. GLB and GLTF files from TRELLIS.2 display with full material and texture support - these are the recommended formats for web and game development. OBJ files work great for simple geometry inspection and are widely supported across all 3D software. STL files are perfect for 3D printing verification, showing mesh integrity before sending to your printer. FBX format provides compatibility with Autodesk products and animation workflows. PLY format supports point cloud data and vertex colors from 3D scanning. VOX files let you preview voxel models. 3MF packages open as a mesh you can orbit before a separate slicing step.

How to Use the 3D Viewer

Getting started is simple. Drag and drop your 3D file onto the viewer area, or click to browse your files. The model loads instantly using our optimized WebGL renderer, and you can start inspecting it right away. Use your mouse to orbit around the model by clicking and dragging. Scroll to zoom in and out for detailed inspection. Right-click and drag to pan the view. On mobile devices, single finger drag to orbit, pinch to zoom, and two-finger drag to pan. The viewer automatically centers and scales your model for optimal viewing.

Integrate with Your 3D Pipeline

After generating 3D models with TRELLIS.2, use this viewer to quickly verify the output before importing into your game engine or 3D software. Check mesh quality by examining polygon distribution and surface smoothness. Verify texture alignment to ensure UV mapping is correct. Inspect material properties to confirm PBR values look accurate. All without the overhead of launching heavy applications like Blender, Maya, or 3ds Max. This rapid iteration workflow helps you identify issues early and refine your TRELLIS.2 prompts for better results.

Common Use Cases

Game Developers: Preview assets before importing to Unity or Unreal Engine. Verify LOD levels and texture resolution meet your performance targets. 3D Artists: Quick inspection of exported models from any 3D software. Check normals, UV seams, and material assignments. Product Designers: Review prototypes and visualizations without specialized CAD software. Share models with clients who don't have 3D software installed. 3D Printing: Verify STL mesh integrity before slicing. Check for non-manifold geometry and inverted normals that could cause print failures. Architects: Preview building models and interior designs. Share walkthroughs with clients via web links.

Technical Specifications

Maximum file size: 50MB. Supported browsers: Chrome, Firefox, Safari, Edge (WebGL 2.0 required). The viewer uses Three.js with custom optimizations for smooth performance. Models are processed entirely client-side using WebAssembly for format parsing. No server upload means your intellectual property stays protected.
