ANNOUNCING ThreeJS Support: Expanding Bitbybit.dev's CAD Capabilities

· 5 min read

A muscle car with two powerful engines under its hood - one representing BabylonJS and the other ThreeJS, both driven by the Bitbybit.dev platform.

We are thrilled to announce the release of two new open-source NPM packages designed to advance our core mission: making 3D CAD (Computer-Aided Design) accessible and adaptable for a broader community of developers. These packages, @bitbybit-dev/threejs and @bitbybit-dev/babylonjs, are critical steps toward our strategic goal of democratizing access to 3D CAD technologies, and they offer significantly greater flexibility for our users.

INTRODUCING BITBYBIT-RUNNER.JS

· 11 min read

Runner is on the loose. A free and powerful tiger in the jungle playing with soap bubbles, symbolizing the freedom to run scripts anywhere.

Update - January 2026

Since this post was originally published, Bitbybit Runner has significantly evolved. What started as a single Babylon.js-based runner has now expanded to support multiple game engines:

  • Babylon.js Runner - The original implementation (full and lite variants)
  • Three.js Runner - Support for the popular Three.js library (full and lite variants)
  • PlayCanvas Runner - Integration with the PlayCanvas game engine (full and lite variants)

Each runner comes in two variants:

  • Full Runner - Includes the game engine in the bundle for quick setup
  • Lite Runner - Excludes the game engine, allowing you to load it separately for better flexibility and smaller bundle sizes

Learn more about using runners with different engines in our comprehensive runner documentation.

In the last couple of weeks, we've been discussing and experimenting with a new way to run and embed Bitbybit.dev scripts. The result of these experiments is a new tool called BITBYBIT-RUNNER.JS. You can now run your scripts on your own websites, blogs, webshops, or third-party coding sites!

RELEASE NOTES 0.15.7: Constraint-Based Circle Creation and Fixes

· 2 min read

A visual representation of new features in Bitbybit.dev v0.15.7, possibly showing circles created through tangential constraints.

This release, version 0.15.7, continues to build upon the geometric capabilities introduced in recent updates. This time, we've implemented a couple of powerful new open-source methods for creating circular edges based on tangential constraints involving other circles or points. Additionally, this release includes some important bug fixes and improvements to our OCCT input classes.

RELEASE NOTES 0.15.6: Advanced Face and Wire Creation from Circles

· 3 min read

A visual representation of new features in Bitbybit.dev v0.15.6, showcasing complex geometries created from circular elements.

This release, version 0.15.6, builds upon the enhancements introduced in our previous update. This time, we've implemented a few powerful new open-source methods focused on creating complex wires and faces from two or more circles. These additions are particularly useful when designing intricate mechanical parts and other geometries involving circular features.
