Point Cloud Visualizer

The Ouster visualization toolkit is written in C++ with Python bindings for Python functionality. It consists of the following:

• simple-viz (viz.SimpleViz): the default Python application visualizer, which can also be used as an entrypoint for more sophisticated custom point cloud visualizations

• ouster_viz: the core C++ library

• ouster.viz: the Python module for the bindings

Using ouster-cli is a fastest way to visualize data from a connected sensor, recorded pcap or OSF files with SLAM poses:

Ouster SDK CLI ouster-cli source OS-1-128.pcap viz visualization of OS1 128 sample data

How to use ouster-cli for visualizations you can learn in Running the Ouster visualizer

For custom visualizations you can explore a programmatically accessible viz.PointViz API below:
