MoveG

A modern C++ library for 3D rotations, poses, and trajectories with comprehensive tooling. MoveG is designed for robotics and computer vision applications, providing a robust foundation for spatial transformations with strong type safety and error checking.

Features

• Robust 3D transformation handling (quaternions, rotation matrices, Euler angles)
• Coordinate frame transformations with error checking
• Modern C++20 implementation
• Comprehensive unit tests with Catch2
• Automated code quality checks
• Memory safety with sanitizers
• High-performance optimizations (LTO, parallel builds)

Key Components

Rotation Library

Provides representation and operations for 3D rotations using quaternions, rotation matrices, Euler angles, and axis-angle representations. Supports conversion between formats, composition of rotations, and angular velocity transformations.

Pose Library

Builds on the rotation library to represent 6-DOF poses (position and orientation). Supports transformation composition, inverse operations, and coordinate frame conversions with proper error handling.

Trajectory Library (Coming Soon)

Will provide capabilities for motion planning and trajectory generation.

Development Tools

• CPM: Package manager for dependency handling
• Catch2: Unit testing framework
• fmt: Modern string formatting library
• Eigen: Linear algebra library
• Clang Tools: Format and static analysis
• Sanitizers: Address, undefined behavior, and leak detection
• Doxygen: Documentation generation
• pre-commit: Git hooks for code quality checks
