## What it is
nvblox is a GPU-accelerated C++/Python library for real-time 3D reconstruction using TSDF and ESDF volumetric mapping, designed for robots with RGB-D cameras. It leverages CUDA and NVIDIA hardware to build, manipulate, and query 3D reconstructions at high runtime performance.

## Use cases
- reconstruct 3D scenes in real time from RGB-D camera data
- compute Euclidean signed distance fields for robot path planning
- build TSDF maps on the GPU for robotic navigation
- fuse depth camera streams into a 3D occupancy reconstruction
- query distance fields for collision avoidance on a robot
- integrate 3D scene reconstruction into a ROS2 robotics stack

## When to choose
- you need real-time TSDF/ESDF reconstruction on NVIDIA GPUs
- your robot uses RGB-D cameras and needs 3D mapping for navigation
- you want a C++, Python, or ROS2 interface for volumetric reconstruction
- runtime performance of 3D reconstruction is critical

## When to avoid
- you don't have an NVIDIA GPU with CUDA support
- you need CPU-only 3D reconstruction
- your project requires a permissive open-source license (license is custom/NVIDIA)
- you need reconstruction from LiDAR rather than RGB-D cameras without extra work
