v0.18 release
Happy new year to all! The Open3D team and many amazing community members bring to you the latest and best Open3D with many new features and bug fixes. Here are the highlights of this release:
- Support for Python 3.11. (Python 3.7 is no longer officially supported.)
- Support for PyTorch 2.0 and TensorFlow 2.14!
cxx11_abi
on Linux between PyTorch and TensorFlow, official Python wheels on Linux only support PyTorch, not TensorFlow. [See #6288] for details. If you'd like to use Open3D with TensorFlow on Linux, you can build Open3D wheel from source in docker with support for Tensorflow (but not PyTorch) as:
cd docker
# Build open3d and open3d-cpu wheels for Python 3.10 with Tensorflow support
export BUILD_PYTORCH_OPS=OFF BUILD_TENSORFLOW_OPS=ON
./docker_build.sh cuda_wheel_py310

v0.17 release
Open3D 0.17 Release Notes
We are happy to bring you the best Open3D yet! This is a "tick" release focused on resolving existing issues and eliminating bugs. We resolved over 150 issues for Open3D and Open3D-ML since the last release.
Here are the main highlights of this release:
- Open3D now has support for differentiable rendering with Mitsuba.
raven_demo2.mp4 |
---|
Here we use Mitsuba to recover the albedo map from an input image for an object in Open3D. Example. |
- New lighter wheel (~105MB) for x86_64 Linux, which is suitable for systems without CUDA. Try it out with:
pip install open3d-cpu
. - The Open3D viewer app is now available for Windows. This version is unsigned, so expect Windows warnings.
- Apple Silicon wheels now come with 3DML support.
- Preview of distributed training with PyTorch for PointPillars on the Waymo dataset.
- PointCloud partitioning with PCA.
Visualization and GUI
[New] Integration with Mitsuba.
- Open3D geometries and materials seamlessly convert to Mitsuba's Principled BSDF:
dataset = o3d.data.MonkeyModel()
mesh = o3d.t.io.read_triangle_mesh(dataset.path)
mesh_center = mesh.get_axis_aligned_bounding_box().get_center()
mesh.material.set_default_properties()
mesh.material.material_name = 'defaultLit'
mesh.material.scalar_properties['metallic'] = 1.0
mesh.material.texture_maps['albedo'] = o3d.t.io.read_image(dataset.path_map['albedo'])
mesh.material.texture_maps['roughness'] = o3d.t.io.read_image(dataset.path_map['roughness'])
mesh.material.texture_maps['metallic'] = o3d.t.io.read_image(dataset.path_map['metallic'])
mi_mesh = mesh.to_mitsuba('monkey')
img = render_mesh(mi_mesh, mesh_center.numpy())
mi.Bitmap(img).write('test.exr')
- Also supports applying other Mitsuba BSDFs to Open3D geometries:
bsdf_rough_plastic = mi.load_dict({
'type': 'roughplastic',
'diffuse_reflectance': {
'type': 'rgb',
'value': [0.1, 0.1, 0.1]
},
'alpha': 0.1,
'int_ior': 'bk7',
'ext_ior': 'air',
})
mi_mesh = mesh.to_mitsuba('monkey', bsdf=bsdf_rough_plastic)
img = render_mesh(mi_mesh, mesh_center.numpy())
mi.Bitmap(img).write('test3.exr')
See examples/python/visualization/to_mitsuba.py
for more details.

0.15 Release
Open3D 0.15 Release Notes
We are excited to bring you the best Open3D yet - version 0.15. Watch the release video here.
Starting from this release, we adopt a "tick-tock" model for balancing resolving issues vs. adding new features. In a nutshell, the "tick" releases are focused on resolving existing issues and eliminating bugs, while the "tock" releases mainly focus on developing new features. Open3D 0.15 is a "tick" release. We resolved over 500 issues for Open3D and Open3D-ML, as the infographic below illustrates.
Google Summer of Code 2022
Open3D has applied for the Google Summer of Code 2022 to increase community participation. Check out details and our project ideas here. Please help in making Open3D better for all.
Build System
- [New] We now provide Open3D binary packages for C++ users. No need to “Build from Source” - just download a binary package for your Operating System and use it “out of the box”. See GitHub releases for v0.15 and getting started guides for the latest development package.
- [New] Docker build tools to build ARM64 Linux wheels and multiple Python versions. See ARM64 build guide for more details.
- [New] Pre-compiled Open3D wheel for ARM64 Linux and macOS. Improved Apple Silicon support. Install Open3D on ARM64 Linux and macOS with
pip install open3d
. - [Update] Open3D now builds with the new CXX11 ABI by default on Linux. Set
-DGLIBCXX_USE_CXX11_ABI=OFF
incmake
if you need the old ABI, e.g. to work with PyTorch / TensorFlow libraries. - [Update] Starting with version 0.15, Open3D Conda packages are no longer supported. Install Open3D with
pip install open3d
inside a Conda virtual environment.
Core
Datasets
- [New] Dataset module for automatically downloading and managing example data. The following example demonstrates how to create a
Dataset
object, extract its path, and display it in the Open3D Visualizer:
import open3d as o3d if __name__ == "__main__": dataset = o3d.data.EaglePointCloud() pcd = o3d.io.read_point_cloud(dataset.path) o3d.visualization.draw(pcd)
#include <string> #include <memory> #include "open3d/Open3D.h" int main() { using namespace open3d; data::EaglePointCloud dataset; auto pcd = io::CreatePointCloudFromFile(dataset.GetPath()); visualization::Draw({pcd}); return 0; }

is no longer required for building Open3D for C++ users. - Open3D-ML is now recommended to be used along with PyTorch 1.8.2 and/or Tensorflow 2.5.2. Checkout Open3D-ML for more information.
Tensorboard Integration
Now you can use Open3D within Tensorboard for interactive 3D visualization! At a glance, you can:
- Save and visualize geometry sequences and their properties. This enables interactive visualization and debugging of 3D data and 3DML model training.
- Visualize 3D semantic segmentation and object detection with input data, ground truth, and predictions. In addition, any custom properties for a
PointCloud
, from scalar to vector, can be easily visualized. - Synchronize time steps and viewpoints during different runs. This helps debug and monitor the effect of parameter tuning.
Rich PBR materials
Object detection
Semantic segmentation
To get started, write some sample geometry data to a TensorBoard summary with this snippet:
from torch.utils.tensorboard import SummaryWriter # TensorFlow also works, see docs.
import open3d as o3d
from open3d.visualization.tensorboard_plugin import summary
from open3d.visualization.tensorboard_plugin.util import to_dict_batch
writer = SummaryWriter("demo_logs/")
cube = o3d.geometry.TriangleMesh.create_box(1, 2, 4)
cube.compute_vertex_normals()
colors = [(1.0, 0.0, 0.0), (0.0, 1.0, 0.0), (0.0, 0.0, 1.0)]
for step in range(3):
cube.paint_uniform_color(colors[step])
writer.add_3d('cube', to_dict_batch([cube]), step=step)
Now you can visualize this in TensorBoard with tensorboard --logdir demo_logs
. For more details on how to use TensorBoard with Open3D, check out this tutorial.
Visualizer
Further enhancements have been added to the GUI viewer. Now you can:
-
Directly visualize tensor-based geometry classes including
PointCloud
,TriangleMesh
, andLineSet
. -
Use physically based rendering (PBR) materials that deliver appealing appearance.

New default lighting environment and skybox improves visual appeal
-
Use all the functionality in Tensorboard!
import open3d as o3d
import open3d.visualization as vis
a_sphere = o3d.geometry.TriangleMesh.create_sphere(2.5, create_uv_map=True)
a_sphere.compute_vertex_normals()
a_sphere = o3d.t.geometry.TriangleMesh.from_legacy(a_sphere)
# Compare this...
vis.draw(a_sphere)
a_sphere.material = vis.Material('defaultLit')
a_sphere.material.texture_maps['albedo'] =
o3d.t.io.read_image('examples/test_data/demo_scene_assets/Tiles074_Color.jpg')
a_sphere.material.texture_maps['roughness'] =
o3d.t.io.read_image('examples/test_data/demo_scene_assets/Tiles074_Roughness.jpg')
a_sphere.material.texture_maps['normal'] =
o3d.t.io.read_image('examples/test_data/demo_scene_assets/Tiles074_NormalDX.jpg')
# With this!
vis.draw(a_sphere)
A complete, complex demo scene can be found at examples/python/gui/demo-scene.py
Core
-
The Open3D
Tensor
class received a major performance boost with the help of Intel ISPC compiler and optimization for the contiguous code path.
(See
python/benchmarks/core
for the benchmark scripts. For each operation, the geometric mean of run times with different data types is reported. The time is measured with an Intel i9-10980XE CPU.) -
A major upgrade of Parallel
HashMap
is done. Now you can choose from multi-valuedHashMap
andHashSet
depending your value types. A comprehensive tutorial is also available. -
Linear Algebra performance have been optimized for small matrices, especially on 4x4 transformations.
-
Semantics for tensor and tensor-based geometry have been improved, especially on device selection.
-
Functions expecting a Tensor now accept Numpy arrays and Python lists. For example:
import open3d as o3d import numpy as np mesh = o3d.t.geometry.TriangleMesh() mesh.vertex['positions'] = np.array([[0, 0, 0], [1, 0, 0], [1, 1, 0]], dtype=np.float32) mesh.vertex['colors'] = np.array([[1, 0, 0], [0, 1, 0], [0, 0, 1]], dtype=np.float32) mesh.triangle['indices'] = [[0, 1, 2]] o3d.visualization.draw(mesh)
I/O
- We now support I/O from/to Numpy compatible
.npz
.npy
formats for Open3D tensors and tensor maps. It is now easier to convert between Open3D geometry classes and Numpy properties. - We have improved I/O performance for tensor-based point cloud and triangle-mesh file-formats, including
.ply
,.pcd
,.pts
. Geometry loading time is hence improved for the stand-alone visualizer app. - We added support for material data to the MessagePack serialization format of the RPC module.
Geometry
-
We introduce a new class
RaycastingScene
with basic ray intersections functions and distance transform for meshes, utilizing the award-winning Intel Embree library.Example code for rendering a depth map:
import open3d as o3d import matplotlib.pyplot as plt # Create scene and add a cube cube = o3d.t.geometry.TriangleMesh.from_legacy(o3d.geometry.TriangleMesh.create_box()) scene = o3d.t.geometry.RaycastingScene() scene.add_triangles(cube) # Use a helper function to create rays for a pinhole camera. rays = scene.create_rays_pinhole(fov_deg=60, center=[0.5,0.5,0.5], eye=[-1,-1,-1], up=[0,0,1], width_px=320, height_px=240) # Compute the ray intersections and visualize the hit distance (depth) ans = scene.cast_rays(rays) plt.imshow(ans['t_hit'].numpy())
Distance transform generated with
RaycastingScene
:See the tutorials for more information (Ray casting, Distance queries).
-
Normal estimation for tensor
PointCloud
is supported with the tensor-compatible nearest neighbor search modules. -
Customizable tensor-based
TriangleMesh
,VoxelBlockGrid
, andLineSet
are implemented that allow user-defined properties. For example:import open3d as o3d import open3d.core as o3c mesh = o3d.t.geometry.TriangleMesh() mesh.vertex["positions"] = o3c.Tensor([[0.0, 0.0, 1.0], [0.0, 1.0, 0.0], [1.0, 0.0, 0.0], [1.0, 1.0, 1.0]], dtype=o3c.float32) mesh.vertex["my_custom_labels"] = o3c.Tensor([0, 1, 2, 4], dtype=o3c.int32) mesh.triangle["indices"] = o3c.Tensor([[0, 1, 2], [1, 2, 3]], dtype=o3c.int32)
Pipelines
- We have enhanced point cloud registration (ICP) with a tensor interface:
- Float64 (double) precision point cloud is supported for a higher numerical stability
- Robust Kernels, including Huber, Tukey, and GM losses are supported for robust registration.
- Colored-ICP is now supported in the unified tensor-based API.
- See this tutorial for more details.

Real-time 3D reconstruction
We introduce a new CUDA accelerated pipeline including RGBD odometry, frame-to-model tracking, and volumetric integration.
Figure 1. Example of 3D reconstruction from an RGB-D sensor.
Odometry
We introduce the tensor based real-time RGBD Odometry pipeline. In addition to the legacy Hybrid and Intensity based methods, we support the popular point-to-plane method.
TSDFVoxelGrid
We further accelerate volumetric integration and introduce fast ray casting for rendering.
VoxelHashing
Based on the accelerated RGBD odometry and raycasting, we present the fully functional VoxelHashing system. It performs dense volumetric reconstruction with fast frame-to-model tracking. We present an easy-to-use GUI that also shows real-time interactable surface reconstruction.
SLAC
We have further enhanced our legacy offline reconstruction system by introducing the Simultaneous Localization and Calibration (SLAC) algorithm. This algorithm applies advanced dense multi-way registration along with non-rigid deformation to create highly-accurate reconstructions.
Real-time point cloud registration
We present a high-performance implementation of ICP using Open3D’ Tensor library. This module is one of the first on leveraging the new Neighbor search module and the newly crafted parallel kernels. This implementation brings support for multi-scale ICP, which allows us to do iterations on different resolutions in order to accelerate convergence while keeping computation low.
Figure 2. ICP registration of multiple point clouds from a driving dataset.
New Neighbor Search module
Neighbor search is at the core of many 3D algorithms. Therefore, it is critical to have access to a fast implementation able to execute a large number of queries in a fraction of a second. After months of development, the Open3D team is proud to present the new Neighbor Search module!
This module brings support for core search algorithms, such as KNN, Radius search, and Hybrid search. All these algorithms are provided with support for both CPU and GPU, through a common and easy-to-use interface. Write your code once and support multiple devices! Moreover, we have not sacrificed a single flop of computation, making this module one of the fastest neighbor search libraries ever created.
Web visualizer
The need for visualizing complex 3D data in web environments has surged considerably in the past few years, in part thanks to the proliferation of sensors like LIDAR and RGBD cameras. New use cases, such as online dataset inspection and remote visualization are now an integral part of many tasks, requiring the crafting of ad-hoc tools, which often are cumbersome to use.
Figure 3. Standalone visualization of a semantic segmentation model in a browser.
In order to improve this situation, we introduce our new web-based visualization module, which enables 3D visualization from any browsers and any location. This module lets users run advanced rendering and visualization pipelines, both remote and locally through your web browser. All the power of Open3D’ rendering engine --including support for PBR materials, multiple lighting systems, 3D ML visualization, and many other features--, are now supported in your browser. This module also includes a Jupyter extension for interactive web-based visualization! This new feature allows you to run compute-intensive 3D processing in a dedicated server while visualizing the results remotely on any device through your browser.

3D Machine Learning
Architectures
In this release, we introduce a new point cloud semantic segmentation architecture based on a Sparse Convolution-based UNet model. This architecture leverages the new sparse convolution operators provided by Open3D, and achieves state of art performance for Semantic Segmentation on the ScanNet dataset. We have also added support for PointRCNN for the task of 3D object detection. To enable PointRCNN we have added new operators like furthest_point_sampling, three_interpolate, ball_query, which are available through Open3D for TensorFlow and Pytorch.
Figure 5. Example of 3D semantic segmentation using a SparseConvUNet model on ScanNet.

Extensions to the Open3D-ML module
The previous release of Open3D introduced an exciting new module dedicated to 3D Machine Learning Open3D-ML, featuring support for 3D semantic segmentation workflows. In this release, we have extended Open3D-ML with the task of 3D object detection. This extension introduces support for new datasets, such as the Waymo Open dataset, Lyft level 5 open data, Argoverse, nuScenes, and KITTI. As always, all these datasets can be visualized out-of-the-box using our visualization tool, from Python or C++. The visualization tool is now equipped with the capability to render 3D bounding boxes along with all the previously existing modalities, e.g. semantic labels, XYZRGB, depth, normals, etc.
Open3D-ML features
PointPillars, the first of the many object detection models to come in the near future. To enable the implementation of PointPillars, we have added a set of new ML operators in Open3D, such as: grid_sampling, NMS, and IOU. These operators are available to the community and can be used to build new models, using our Python and C++ APIs.
import os
import open3d.ml as _ml3d
import open3d.ml.torch as ml3d
cfg_file = "ml3d/configs/pointpillars_kitti.yml"
cfg = _ml3d.utils.Config.load_from_file(cfg_file)
model = ml3d.models.PointPillars(**cfg.model)
cfg.dataset['dataset_path'] = "/path/to/your/dataset"
dataset = ml3d.datasets.KITTI(cfg.dataset.pop('dataset_path', None), **cfg.dataset)
pipeline = ml3d.pipelines.ObjectDetection(model, dataset=dataset, device="gpu", **cfg.pipeline)
...
# run inference on a single example.
result = pipeline.run_inference(data)
We have also updated our model zoo, providing new pretrained models on KITTI for the task of 3D object detection, and new semantic segmentation models on Paris-Lille3D and Semantic3D.
Remember that all the tools provided in Open3D-ML are compatible with PyTorch and TensorFlow!
Support for RealSense SDK v2
RealSense sensors’ support has been upgraded to leverage the RealSense SDK v2. Users can now capture crisp 3D data from L515 devices. As part of this upgrade, we include support for Bag files format (RSBagReader), and direct streaming from sensors. These operations can now be done through a new sensor class: RealSenseSensor, offering a simple and intuitive way to control your sensors.
import open3d as o3d
bag_reader = o3d.t.io.RSBagReader()
bag_reader.open(bag_filename)
while not bag_reader.is_eof():
im_rgbd = bag_reader.next_frame()
# process im_rgbd.depth and im_rgbd.color
bag_reader.close()
import json
import open3d as o3d
with open(config_filename) as cf:
rs_cfg = o3d.t.io.RealSenseSensorConfig(json.load(cf))
rs = o3d.t.io.RealSenseSensor()
rs.init_sensor(rs_cfg, 0, bag_filename)
rs.start_capture(True) # true: start recording with capture
for fid in range(150):
im_rgbd = rs.capture_frame(True, True) # wait for frames and align them
# process im_rgbd.depth and im_rgbd.color
rs.stop_capture()
For further information, check this tutorial.
CORE and 3D reconstruction
Open3D 0.12 brings exciting CORE upgrades, including a new Neighbor Search module. This module supports typical neighbor search methods, such as KNN, radius search, and hybrid search, on both CPUs and GPUs, under a common interface!
Furthermore, we have created a new version of the TSDF integration algorithm accelerated on GPU. This version is able to achieve outstanding computational performance, requiring between 2 and 4 ms to integrate a pair of frames.
New rendering functionalities
We have done an important effort over the last months to put out a modern, real-time, rendering API. This effort is still ongoing, and we are committed to bringing top-tier rendering capabilities with a strong emphasis in performance, versatility, ease of use, and beauty. As part of our commitment, in this release we have added relevant extensions to this API:
- Support for Screen-space reflections
- Full programmatic support for headless rendering in Filament (for real)
box = o3d.geometry.TriangleMesh.create_box(2, 2, 1)
render = rendering.OffscreenRenderer(640, 480)
render.scene.add_geometry("box", box, grey)
render.scene.camera.look_at([0, 0, 0], [0, 10, 0], [0, 0, 1])
img = render.render_to_image()
- Support for arbitrary camera intrinsic matrices: A small step for the Camera class; a very anticipated step by the Open3D community
