Convert to X3D from any model format supported by Castle Game Engine (glTF, X3D, VRML, Wavefront OBJ, STL, Collada, 3DS, MD3, Spine JSON and others).
Convert between X3D encodings and pretty-print X3D (when both the input and output is X3D).
This tool is completely free (for any usage, commercial or not). If you find it useful please support me on Patreon.
Advanced usage notes:
You can upload multiple files (select them with Ctrl key in the open dialog) if it makes sense for the given model format. E.g. upload glTF JSON + optional binary data, or Wavefront OBJ + optional MTL file.
This online converter has some limits on the uploaded file size and conversion time. If needed you can just download view3dscene (and tovrmlx3d) and perform the same conversion on your own computer, without any limits. You can also generate screenshots or perform mass conversion from your scripts this way.
The models you upload here, and the resulting output, are not stored on the server longer than absolutely necessary (to perform the conversion, and then the output is kept for 15 minutes to allow you download it). Your models remain yours, we don't keep them.
