Online 3D Model Viewer (Free Inspection Tool)

Why Use an Online 3D Model Viewer?

 

For 3D developers, designers, and content creators, model preview and inspection are indispensable parts of the daily workflow. The traditional approach often involves opening heavy professional software (like Blender, Maya, or Unity) and enduring lengthy loading times.

A professional online 3D model viewer solves this problem. It offers a lightweight, installation-free, cross-platform solution, allowing you to instantly perform the following tasks via a browser on any device:

1. Quick Inspection: Swiftly check for common issues like missing textures, inverted normals, or incorrect axis orientation before uploading models to your project.

2. Instant Sharing: Easily share model links within your team or with clients, without worrying about whether the recipient has specific 3D software installed.

3. Format Compatibility: View all major formats in one unified interface, avoiding viewing failures caused by software compatibility issues.

 

Which Mainstream 3D Formats Does the Yang3D Viewer Support?

 

As a viewer optimized for the Web 3D workflow, Yang3D is designed to offer extensive format compatibility, allowing you to preview the vast majority of commonly used 3D files within a single interface:

• Web Optimized Formats: glTF (.gltf) and GLB (.glb). We encourage you to use these formats as they are built for WebGL performance.

• Common Exchange Formats: OBJ (.obj), FBX (.fbx). Even traditional model files can be quickly loaded for preview.

• Other Formats: Support for common PLY and STL file formats (STL, in particular, is crucial for 3D printing users).

 

Core Features: More Than Just "Viewing"—In-Depth Model Inspection and Debugging

 

The design philosophy of the Yang3D viewer is to provide powerful Inspection capabilities, helping you to identify and resolve potential issues before deploying your model to a production environment.

 

H3: PBR Material Visualization

 

We fully support the PBR (Physically Based Rendering) standard. You can manually adjust the scene's lighting environment to check the model's key maps:

• Base Color

• Metallic

• Roughness

• Normal Map This is essential for ensuring the model renders with the expected lighting and shading effects in Three.js or Babylon.js.

 

H3: Wireframe Mode & Geometry Information

 

By switching to Wireframe Mode, you can visually inspect the model's topology and structure. At the same time, the viewer displays critical geometry data in real-time, such as:

• Vertices Count

• Face Count

• Triangle Count

 

H3: Scene Hierarchy and Animation Debugging

 

For complex glTF/FBX models, you can view the complete Scene Hierarchy to examine the relationship between bones and nodes. If the model includes animation, you can pause, play, and inspect the animation frame by frame to quickly locate animation errors or glitches.

 

Yang3D's Guarantee of Security and High Performance

 

When dealing with sensitive 3D model files, privacy and performance are what users care about most.

• Absolute Privacy, Local Processing: Like our format converter tool, the Yang3D 3D Model Viewer uses pure client-side processing technology. The files you select are read and rendered locally in your browser and are not uploaded to our servers. Use it with confidence, knowing your model assets remain completely under your control.

• WebGPU/WebGL Acceleration: We leverage the latest WebGPU or WebGL technology stack to ensure that even large models containing millions of polygons maintain a smooth frame rate (FPS) in modern browsers.
