The Problem

Waymo Open Dataset is one of the richest public self-driving datasets out there, but actually looking at the data is painful. The official tools need Python + TensorFlow. Jupyter gives you static plots. Foxglove is paid. And you can't even use the raw Parquet files without preprocessing scripts.

You just want to drop in the files and see what's inside.

What's Inside

• See what the car sees: explore real self-driving scenes in 3D with LiDAR point clouds and 5 synchronized camera views
• 3D object models: vehicles, pedestrians, and cyclists rendered as 3D models with color-coded tracking
• Camera POV mode: click a camera to jump into its viewpoint in 3D, compare what the sensor sees side by side
• Cross-modal linking: hover over a camera detection and its 3D counterpart lights up, and vice versa
