Detailed Description

Visualize gz::msgs::PointCloudPacked messages in a 3D scene.

By default, the whole cloud is displayed using a single color. Users can optionally choose a topic publishing gz::msgs::FloatV messages which will be used to color all points with a color gradient according to their values. The float message must have the same number of elements as the point cloud and be indexed the same way. NaN values on the FloatV message aren't displayed.

Requirements:

Parameters:

  • <point_cloud_topic>: Topic to receive gz::msgs::PointCloudPacked messages.
  • <float_v_topic>: Topic to receive gz::msgs::FloatV messages.
