This branch introduces a C++ backend. This backend is designed to provide better C++ plugin features for handling block-memory.

Summary of Key Changes

  • New C++ backend

    • A new C++ backend has been added in the backend directory.
    • Includes:
      • CMake build system
      • Source code for block-memory Cosserat rods
      • Concurrent Collision detection and its optimization.

  • Pybind11 bindings

    • Pybind11 is used to create Python bindings for the C++ code.
    • Enables seamless integration with the existing Python codebase.

  • Python modules

    • Python modules have been added to interface with the C++ backend.

  • Unit tests

    • The C++ code
    • Python–C++ integration

  • GitHub Actions

    • Build the C++ backend
    • Run tests
