Official Announcing: the Unity Robotics Visualizations Package

We have a new release!

With the new Visualization package, our existing ROS connection package can now display visualizations of most of the common ROS message types. Use the predefined visualizers or write your own: draw 3d lines, shapes, labels, point clouds, and meshes, or 2d GUI elements such as text and images, however you see fit.

You can read more in our release blog:

Or dive right in with our Nav2-SLAM example, which demonstrates navigation with visualizations.

Sure! If your lidar is sending ROS LaserScan messages it should Just Work™.

If you're not using ROS, you can write your own code to instantiate a PointCloudDrawing yourself, and draw points on it manually - just place the Drawing3dManager prefab in your scene and write something like:

Code (CSharp):

1. Drawing3d drawing = Drawing3dManager.CreateDrawing();
2. PointCloudDrawing pointCloud = drawing.AddPointCloud(numPoints);
3. foreach(...)
4. {
5.     pointCloud.AddPoint(position, color, radius);
6. }

For efficiency, rather than making a new PointCloudDrawing each time, you should keep a reference to the same one, and call Clear() before you redraw it.
