This tool provides a way to convert 3D models (in the .ply format) into a more human-readable format (.json, which can be conveniently read using Firefox, for example). This is mainly for personal interest and trying to better understand how 3D model data is represented.
Models can be exported to the ply format from Blender or other 3D modeling software. Alternatively, free model downloads (in ply format) are available from sites such as Artec3D and Sketchfab.
Note that ply file formatting can vary between implementations, so some models may not render correctly. The JSON conversion should work regardless. The source code for this tool is available on github.
