PROFILE
Dylan Turpin
Worked on the newton-physics/newton repository, delivering core enhancements to its physics engine and developer tooling over three months. Developed and integrated advanced solvers for articulated rigid body dynamics and semi-implicit integration, aligning APIs for maintainability. Improved collision detection by refining geometric calculations and visualization using OpenGL, enabling clearer diagnostics. Expanded inverse kinematics capabilities with a velocity-space solver and floating-base support, while introducing an interactive 3D gizmo toolkit for real-time manipulation. Modernized the codebase by raising the minimum Python version and adopting new type-checking syntax. Utilized C++, Python, and CUDA, emphasizing code organization, refactoring, and robust simulation fidelity.

Aug 1, 20252025-08 monthly summary for newton-physics/newton. Key accomplishments include delivering expanded inverse kinematics capabilities and platform modernization. Specifically, switched IK solver to velocity-space formulation to support all joint types, added a floating-base option for robot models, and performed extensive refactoring and testing. Upgraded platform compatibility by removing Python 3.9 support and raising the minimum Python to 3.10 across pyproject.toml and uv.lock, while adopting a pipe operator for type checks. These changes improve hardware compatibility, code quality, and future maintainability. Overall impact: broader hardware support, improved stability, easier onboarding for contributors, and a leaner, type-safe codebase.

Jul 1, 2025July 2025 performance highlights for newton-physics/newton: Delivered two major features enhancing physics realism, tooling, and developer productivity. IK Module with Benchmarking and Interactive Playground provides a robust inverse kinematics solver with multiple Jacobian methods, integrated performance analysis, and a real-time playground for experimentation and benchmarking. Interactive 3D Manipulation Gizmo Toolkit adds a comprehensive gizmo.py with helper classes for 3D arrows/arcs, including collision detection, rendering, and intuitive drag/rotate interactions to improve visualization and manipulation workflows within the engine. A follow-up fix ensures gizmo.py helper availability to maintain tooling reliability.

May 1, 2025May 2025 performance summary for newton-physics/newton: Delivered key physics engine enhancements, visualization improvements, and robust collision detection, driving higher fidelity simulations and faster debugging. Implemented FeatherstoneSolver and SemiImplicitSolver with API alignment across the engine, migrated relevant helpers to the euler_solver module, and updated licensing and usage notes to reflect the changes. Enhanced OpenGL cloth self-contact visualization by hiding the ground plane and rendering in wireframe by default for clearer inspection. Fixed collision detection accuracy by incorporating radii for shapes (sphere, capsule, cylinder, cone) and accounting for thickness in penetration depth and total separation calculations. These efforts collectively improve simulation fidelity, developer productivity, and maintainability, delivering tangible business value.
