- **Category:** 3D Models

- **Supported formats:** .obj

## Overview

This OBJ viewer renders Wavefront OBJ 3D models directly in your browser using WebGL. OBJ (.obj) is one of the oldest and most widely supported 3D geometry formats, used across virtually all 3D software. Pick a sample model or choose your own .obj file to preview it in an interactive 3D viewport, with no upload.

## When to use

- You received an .obj file and want to view it without 3D modeling software.
- You need a quick, private preview of a 3D mesh before importing.
- You want to inspect an OBJ model's geometry on any device.

## How it works

- Select a built-in sample model or choose your own .obj file.
- The viewer loads the model with WebGL (three.js) in your browser — nothing is uploaded.
- Rotate, zoom and pan to inspect the 3D mesh.

## Use cases

- Previewing 3D scan data and meshes.
- Inspecting OBJ exports from CAD and modeling tools.
- Checking 3D print models.

## Samples

- **Sample OBJ Model**: A OBJ 3D model sample for in-browser preview

## Frequently asked questions

### What is an OBJ file?

OBJ (.obj) is a geometry definition file format developed by Wavefront Technologies in 1990. It stores 3D mesh data — vertices, UV coordinates, normals, faces and material references — as plain text, making it one of the most universal 3D formats.

### Are my OBJ files uploaded?

No. Models you open from your device stay on your device and are rendered locally with WebGL. Only the public sample model is requested from the server.

### Does OBJ include materials and textures?

OBJ stores geometry only. Materials are defined in a separate .mtl (material template library) file that references texture images. The viewer loads the geometry; material files are loaded when available alongside the .obj.
