OBJ to 3D Tiles Converter

Easily convert your 3D models from the OBJ (Wavefront) format into 3D Tiles, an efficient, open specification designed for streaming and visualizing massive 3D geospatial datasets on the web using platforms like CesiumJS or other WebGL-based viewers.

Supported Input Format

This converter accepts a ZIP archive containing the components of your 3D model in Wavefront OBJ format, including:

.obj file

This is the primary file that stores your 3D model's geometry data, including:

  • Vertices
  • Faces (polygons or triangles)
  • Normals (optional)
  • Texture coordinates (UV mapping)
  • References to materials (defined in the .mtl file)

.mtl file

The Material Template Library file defines the materials used in your OBJ model, including:

  • Surface color (diffuse)
  • Specularity
  • Transparency
  • Shininess
  • Links to external texture files

Texture Images

These are external image files referenced in the .mtl file that are used for texturing the 3D model:

  • Common formats: .jpg, .jpeg, .png
  • Can include diffuse, normal, bump, or specular maps

ZIP Archive Requirements

To ensure proper conversion, your ZIP archive must contain all related files:

  • model.obj
  • model.mtl (must be referenced correctly in the .obj file)
  • All texture images used by the .mtl file (diffuse.jpg, normal.png, etc.)

Important Tips

  • All files should be in the root of the ZIP (no nested folders unless supported)
  • The .obj file must correctly reference the .mtl file using the mtllib directive (e.g., mtllib model.mtl)
  • The .mtl file must reference texture images using map_Kd or similar tags (e.g., map_Kd diffuse.jpg)

Output Format: 3D Tiles (glTF-based)

After conversion, your model will be available in 3D Tiles format, which:

  • Contains a tileset.json along with LOD of b3dm files
  • Supports efficient streaming and rendering of large-scale 3D data
  • Is ideal for web-based 3D applications (e.g., digital twins, GIS, smart cities)

Free Tier Limitations

  • Maximum ZIP size: 250 MB
  • For larger datasets or enterprise features, consider premium options or local CLI tools
