chandlerprall/Physijs
Mar 2012 - Jul 2022
Physics plugin for Three.js
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 review, 191 commits, 4 PRs in 10 years 5 months
Contributions summary:Chandler primarily focused on implementing new shape primitives, including ConeMesh, TriangleMesh, and ConvexMesh, along with methods like setAngularVelocity, applyImpulse, setLinearVelocity, and setDamping, which extend the functionality of the Physijs library. These additions enable more complex physics simulations and interaction with Three.js objects. They also integrated a collision reporting system for better object interactions, which improves overall system performance and debugging capabilities. In addition to the new features, they also fixed various bugs.

chandlerprall/ThreeCSG
Apr 2012 - Oct 2022
CSG plugin for Three.js
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:1 review, 39 commits, 12 PRs in 10 years 8 months
Contributions summary:Chandler primarily contributed to the `ThreeCSG` library by implementing features and optimizations related to geometry manipulation and the conversion of geometry to meshes. They refactored code to improve vertex handling, including optimizations like vertex sharing and the addition of normal and UV support. Their work involved adapting the library to newer versions of Three.js and enhancing the functionality of the CSG operations.
