Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Gravity Sketch

  • Free plan limited to 150MB cloud storage and 3 simultaneous users per room
  • File format support limited to OBJ and STL on free plan; other formats require paid plan
  • Evaluation tools (surface contours, viewpoints, section tool) not available on free tier
  • VR access requires Meta Quest, Steam, or web app; limited to specific platforms
  • Data localisation only available on Enterprise plan

Three.js

  • Forward rendering pipeline only, no deferred rendering support
  • No built-in collision detection or spatial indexing, requiring external physics libraries
  • WebGL dependency means no support for non-WebGL environments

Answered from the vendors’ own pages

Three.js: Is Three.js free to use?

Yes. Three.js is released under the MIT license, an open-source license that permits unlimited commercial and personal use with no licensing fees.

Source
Three.js: Does Three.js include physics simulation?

No. Three.js is a rendering library only. Physics, collision detection, and spatial indexing must be implemented with external libraries like Rapier, Ammo, or JoltPhysics.

Source
Three.js: Can I use Three.js for offline development?

Yes. Local development requires a local web server for CORS compliance. You can use npm with a build tool like Vite, or run a local Python server for development.

Source
Three.js: Does Three.js support WebXR for VR/AR?

Yes. Three.js documentation includes WebXR APIs for building VR and AR experiences in web browsers.
