# Open3D: A Modern Library for 3D Data Processing
Open3D is an open-source library that supports rapid development of software
that deals with 3D data. The Open3D frontend exposes a set of carefully selected
data structures and algorithms in both C++ and Python. The backend is highly
optimized and is set up for parallelization. We welcome contributions from
the open-source community.
**Core features of Open3D include:**
- 3D data structures
- 3D data processing algorithms
- Scene reconstruction
- Surface alignment
- 3D visualization
- Physically based rendering (PBR)
- 3D machine learning support with PyTorch and TensorFlow
- GPU acceleration for core 3D operations
- Available in C++ and Python
Here's a brief overview of the different components of Open3D and how they fit
together to enable full end to end pipelines:

From the author:
> Throughout the book, I showcase how Open3D enables efficient point cloud
> processing, mesh manipulation, and 3D visualization through practical examples
> and code samples. Readers learn to leverage Open3D's powerful capabilities for
> registration, segmentation, and feature extraction in real-world 3D data
> science workflows.
## Python quick start
Pre-built pip packages support Ubuntu 20.04+, macOS 10.15+ and Windows 10+
(64-bit) with Python 3.10-3.14.
```bash
# Install
pip install open3d # or
pip install open3d-cpu # Smaller CPU only wheel on x86_64 Linux (v0.17+)
# Verify installation
python -c "import open3d as o3d; print(o3d.__version__)"
# Python API
python -c "import open3d as o3d; \
mesh = o3d.geometry.TriangleMesh.create_sphere(); \
mesh.compute_vertex_normals(); \
o3d.visualization.draw(mesh, raw_mode=True)"
# Open3D CLI
open3d example visualization/draw
```
To get the latest features in Open3D, install the
[development pip package](https://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
To compile Open3D from source, refer to
[compiling from source](https://www.open3d.org/docs/release/compilation.html).
Release artifacts (Python wheels and C++ binaries) include signed
[SLSA](https://slsa.dev) build-provenance attestations (GitHub Artifact
Attestations), aligned with [OpenSSF](https://openssf.org) supply-chain
guidance. See
[Getting started — supply chain attestations](https://www.open3d.org/docs/latest/getting_started.html#supply-chain-attestations)
for verification with the GitHub CLI.
## C++ quick start
Checkout the following links to get started with Open3D C++ API
- Download Open3D binary package: [Release](https://github.com/isl-org/Open3D/releases) or [latest development version](https://www.open3d.org/docs/latest/getting_started.html#c)
- [Compiling Open3D from source](https://www.open3d.org/docs/release/compilation.html)
- [Open3D C++ API](https://www.open3d.org/docs/release/cpp_api.html)
To use Open3D in your C++ project, checkout the following examples
- [Find Pre-Installed Open3D Package in CMake](https://github.com/isl-org/open3d-cmake-find-package)
- [Use Open3D as a CMake External Project](https://github.com/isl-org/open3d-cmake-external-project)
## Open3D-Viewer app
Open3D-Viewer is a standalone 3D viewer app available on Debian (Ubuntu), macOS
and Windows. Download Open3D Viewer from the
[release page](https://github.com/isl-org/Open3D/releases).
## Open3D-ML
Open3D-ML is an extension of Open3D for 3D machine learning tasks. It builds on
top of the Open3D core library and extends it with machine learning tools for
3D data processing. To try it out, install Open3D with PyTorch or TensorFlow and check out
[Open3D-ML](https://github.com/isl-org/Open3D-ML).
