This 3D model viewer supports multiple 3D model formats and can rotate, zoom, and pan to view 3D models in the browser.

What are 3D Model Formats?

3D model formats are used to store three-dimensional geometric data. Common formats include:

• STL (Stereolithography)：Triangle mesh format widely used for 3D printing
• OBJ (Wavefront OBJ)：Universal 3D model format supporting vertices, faces, and texture coordinates
• GLTF (GL Transmission Format)：Web-optimized 3D model format supporting materials and animations
• GLB：Binary version of GLTF
