A CUDA-accelerated library for rapid 3D data processing in robotics, enabling GPU-powered SLAM, collision avoidance, and path planning.
Cupoch is a CUDA-accelerated library for rapid 3D data processing in robotics. It provides GPU-powered implementations of algorithms for tasks like point cloud registration, visual odometry, collision checking, and path planning, significantly speeding up computations compared to CPU-based approaches. The library is based on Open3D but extends it with robotics-specific features and GPU optimization.
Robotics researchers and engineers working on SLAM, autonomous navigation, and 3D perception who need real-time performance for processing large 3D datasets, such as point clouds and RGB-D images.
Developers choose Cupoch for its GPU acceleration, which offers substantial speedups in 3D data processing, its comprehensive set of robotics algorithms, and its interoperability with popular frameworks like PyTorch via DLPack.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarks in the README show significant speedups over CPU-based Open3D, with up to 100x faster point cloud processing for tasks like registration and filtering, enabling real-time robotics applications.
Provides a comprehensive suite of algorithms for SLAM, visual odometry, collision detection, and path planning, as listed in the core features, tailored specifically for robotic systems.
Supports DLPack for seamless data exchange with PyTorch and CuPy, allowing easy integration with machine learning pipelines for tasks like 3D perception and deep learning.
Includes an interactive GUI with OpenGL CUDA interop and ImGui, demonstrated in examples, for immediate 3D data rendering and debugging during development.
Exclusively relies on NVIDIA GPUs and CUDA, making it incompatible with AMD GPUs or CPU-only systems, which restricts deployment flexibility and adds vendor dependency.
Installation from source requires specific CUDA versions, dependencies, and workarounds, as shown in the Jetson Nano setup, which can be error-prone and time-consuming.
Some algorithms, like KNN optimization, are marked as work in progress (WIP) in the README, indicating that the library is still evolving and may lack full robustness or documentation.
The README notes GL driver errors requiring environment variable workarounds, suggesting potential stability problems on non-standard or older systems.
