3D View

This article was written for version 2.0.9 of Core. Click here for the most recent version of the help center.

3D View is a Studio plugin designed to visualize and explore data from various sensing modalities. It can be used to visualize most types of both live and recorded sensor data.

By default sensor data is visualized in the vehicle centred coordinate frame, with origin at the center of the rear axle on the ground.

Studio 3D View

The 3D View plugin can be loaded from the plugin selector on the right-hand sidebar in Studio.

The perspective in 3D View is initialized to the origin of the coordinate frame in perspective mode. Tilt and pan the perspective by clicking and dragging in the plugin window. There are preset perspective views that can be toggled from the control panel─or right-clicking in the 3D View plugin─such as “Birds Eye” and “Perspective”.

There are a few keyboard commands that offer control over the perspective of the camera.

1. Drawable primitive types

The left-hand sidebar has settings for controlling how data is drawn in the 3D View plugin.

1.1 Lane model

The ps_lane_model_msg is always drawn as yellow lines with the curvature and distance-from-origin as defined in the incoming message.

1.2 LiDAR points

LiDAR points are represented as the small dots, and come from the ps_lidar_points_msg.

1.3 Objects

Drawn as rectangles with the width, height and length as defined in the ps_objects_msg.

Objects have many classification types, which can be toggled from the left-hand control panel.

1.4 RADAR targets

RADAR targets are drawn as spheres or orbs within 3D View. By default each RADAR source (sensor) produces different color spheres.

ps_radar_targets_msg with the following range type, status, and quality are not drawn in 3D View.

    target.getRangeType() == RANGE_INVALID or
    trackStatus == TRACK_STATUS_INVALID or
    trackStatus == TRACK_STATUS_NO_TRACK or
    target.getQuality() == QUALITY_INVALID

By default the RADAR target sizes within 3D view are scaled by their amplitude. The larger amplitude returned, the larger the spheres are drawn.
